After upgrading to macOS Catalina with latest Xcode 11, I am not able to read files directly from user path when doing unit testing, example:
PROJECT_DIR + "/FolderX/myFile.json",
I keep getting error Thread 1: EXC_BAD_ACCESS (code=1, address=0x8)
This is also happened when I am trying to open a couchbase lite database with custom path.
Error:
error opening!: 14
Cannot open database, Error : Error Domain=SQLite Code=14 "unable to open database file" UserInfo={NSLocalizedDescription=unable to open database file}
I believe this is an issue due to the read write access between my simulator and the latest Catalina.
My current workaround is to add my files and database to target membership and read the files directly from [NSBundle bundleForClass:[self class]].bundlePath.
Is there any better fix to this? Like tweaking any setting to allow it to read files from custom path like in older versions?
You might try looking in SystemPreferences > Security&Privacy > Privacy tab. From there, scroll down to "Files and Folders" <-- There's where you can see programs and the folders they have been granted access to in Catalina.
Personally, I didn't have time to waste figuring out how the new file permissions are supposed to work, so I let Xcode have full disk permission. (Right above the "files and folders" is "Full Disk Access".
Of course, that solved all my issues... after I get a chance to play with the new file permissions, I may revoke that access and give it explicit folder access.
Well if anyone is still struggling with this, I've moved all my projects outside of ~/Documents/
it is strange that projects under ~/Documents/ doesnt get asked for read permission, other paths do!
I end up putting all my projects under ~/workspace/
** for those who doesnt know, ~/ means /Users/{your username}/
Check your File Access settings in the App Sandbox in your project's settings, under Signing and Capabilities. For example, I couldn't access files in /Users/Bert/Downloads, even after turning on Full Disk Access in Security and Privacy in System Preferences. I had to grant read access to the Downloads Folder in App Sandbox settings.
I have a list view in my app, some data is saving to the database before populating list view.
My problem is that can't see the data, and how to verify the data is stored in the database.
I am giving the solution for Visual Studio 2015 (worked for Xamarin).
Locate the database file mentioned in above image, and click on Pull button as it shown in image 2.
Save the file in your desired location.
You can open that file using SQLite Studio or DB Browser for SQLite to verify your data is saved.
You can use use a SQLite browser, such as the open-source multi-platform DB Browser for SQLite, or another tool of your choice.
Getting access to the sqlite file is the next thing:
iOS Simulator:
/Users/administrator/Library/Application Support/iPhone Simulator
You can browse simulator files from that directory in Mac OS X.
Android Emulator:
You can use the command line via adb shell command for browsing file system:
ls - list current directory
cd - change current directory
Once you find the Sqlite file for your app, you can use the pull cmd for copying the file from device (or emulator image):
adb pull /sdcard/file.txt file.txt
I solved this problem in a few steps:
On Windows:
Download a SQLite viewer, for example SQLiteStudio.
Find where the .db or .db3 file is stored, i did it this way:
var databasePath = Path.Combine(FileSystem.AppDataDirectory, "localDB.db3");
Console.WriteLine(databasePath);
For me the path was: /data/user/0/com.companyname.[name]/files/localDB.db3
Find where the Android Debug Bridge (adb) .exe is stored. For me it was stored at: C:\Users[user]\AppData\Local\Android\Sdk\platform-tools. (AppData is a hidden folder, so make sure that hidden folders are visible.
Open a command prompt at this folder.
Try to copy the database file to a local folder on your machine by entering the following line into the command prompt:
adb pull [path to database] [path to local folder]
results in:
adb pull /data/user/0/com.companyname.[name]/files/localDB.db3 C:\Users\[user]\Desktop
If you get an error "Failed to stat remote object ... Permission denied", you have to make sure you have root permission. To do this, enter the following line in the command prompt:
adb root
Try to copy the file again.
If the file is succesfully copied, open it with SQLiteStudio.
et voila
Here is how you can access the sqlite database file in xamarin forms using Rider IDE:
Set your db path
private string GetDatabasePath()
{
return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "db.db");
}
Logging Environment.GetFolderPath(Environment.SpecialFolder.Personal) prints this path on my device
/data/user/0/com.companyname.landpriceexplorer/files
Click the Device File Explorer tab on the right side.
Search for the database file in the device file explorer.
Double click the file to add to the data source.
Open the Database tab and browse your data there.
I have created a DB by realm and I am not able to find the file as my OS (Yosemite) dont have a mobile folder in the /private/var/mobile.
How should I access my realm to run in the browser?

Finding a Realm File
For Android
How to view my Realm file in the Realm Browser?
For iOS
If your App is on Device
Make sure that your device is connected and go to the devices window in the Xcode menu Window > Devices (⌘⇧2). There you will be able to choose your device and your app from a list of installed apps with debugging permissions.
After selecting your app, go to the cog in the toolbar at the bottom of the table view and select “Download Container…“. There you will be able to pull the file from the documents location to your Mac. It will be saved as an xcappdata bundle.
When you open the local path in Finder, where you saved it, you can tap into that by selecting “Show Package Contents” in the context menu of the finder, when you select the file. A new finder window will open, where you find your Realm inside in the following path (e.g.): AppData/Documents/default.realm (The directory '/private/var/mobile' is the path, which is used by iOS on the device filesystem.
If your App is on the Simulator
Go to your user’s directory:
/Users/<username>/Library/Developer/CoreSimulator/Devices/<simulator-uuid>/data/Containers/Data/Application/<application-uuid>/Documents/default.realm
Probably the easiest way to get the current path of the default realm is to pause the simulator and enter the following into the LLDB console:
Objective-C:
(lldb) po [RLMRealmConfiguration defaultConfiguration].fileURL
Swift using Realm Objective-C:
(lldb) po RLMRealmConfiguration.defaultConfiguration().fileURL
Swift using Realm Swift:
(lldb) po Realm.Configuration.defaultConfiguration.fileURL
Or if you have an RLMRealm instance at hand, you can use:
(lldb) po myRealm.configuration.fileURL
Then just copy this path, open your terminal, and type open [Pasted path here]
NOTE: Some paths have a space in them so be sure to use "\" before the space to escape it
Helper Tool SimPholders
This is probably the fastest way to find the file of an app in the simulator. Install SimPholders. This will allow you to access your app’s documents directory directly from your menu bar.
Note Some people have mentioned that SimPholders has taken them to the wrong simulator app folder, if that's the case for you, print out your realm path by following the steps above, printing out your realm.path
I found most simplest way for iOS/macOS
(for swift 3 Xcode 8.3)
override func viewDidLoad() {
// for swift 2.0 Xcode 7
print(Realm.Configuration.defaultConfiguration.fileURL!)
}
Then x code will log the correct path, check the screen below.
Now open your Finder and press ⌘ + ⇧ + G (command+shift+G) and paste the path that logs on your Xcode
One Easy Alternative For Simulator Apps
Create a smart folder/search in Finder. Gives quick and easy clickable access to all your realm files.
Open the folder /Users/$USER/Library/Developer/CoreSimulator/Devices in Finder.
With terminal open /Users/$USER/Library/Developer/CoreSimulator/Devices
Search for .realm
Change the search to look in the "Devices" folder only.
Save the search to your sidebar (e.g. as Realms)
When sorted by date this will give you a quick and easy clickable list of the latest modified Simulator .realm files.
Here is an easy solution.. I messed with this for awhile. I should point out, this is a specific set of instructions using Android Studio and the AVD Emulator.
1) Start the Emulator and run your app.
2) While the app is still running, open the Android Device Monitor. (its in the toolbar next to the AVD and SDK manager icons)
3) Click the File Explorer tab in the Device Monitor. There should be a lot of folders.
4) Navigate the following path: Data > Data > Your Package Name > files > Default.Realm (or whatever you named it)
Ex. If you are using one of the realm example projects, the path would be something like Data>Data>io.realm.examples.realmgridview>files>default.realm
5) Highlight the file, click the Floppy Disk icon in the upper right area "pull a file from the device"
6) Save it off to whereever you want and done.
What I did was to use
let realm = Realm(path: "/Users/me/Desktop/TestRealm.realm")
and then it gets created in full view on my desktop and I can double-click to launch the Realm Browser on it. Later, I can remove the parameter and let it use the default location when I'm satisfied that all is working as expected.
The above answers missing a way to find the realm file in Android platform and believe me this way will save your lot's of time which we generally waste in other approaches to get the realm file. So let's start...
First open "Device File Explorer" in android studio(View -> Tools Windows
-> Device File Explorer.
This will open your device explorer.
now open data -> data -> (your_app_package_name) -> files -> default.realm
default.realm is the file for which we are here. Now Save_as this file at your location and access the file from the realm_browser and you will get your database.
NOTE: Mentioned approach is tested on non-rooted phone(one+3).
Objective-C - [RLMRealmConfiguration defaultConfiguration].fileURL
NSLog(#"%#",[RLMRealmConfiguration defaultConfiguration].fileURL);
Eg-/Users/"Your-user-name"/Library/Developer/CoreSimulator/Devices/E58645FF-90DE-434D-B2EB-FA145EB6F2EA/data/Containers/Data/Application/E427BD21-2CB1-4F64-9ADF-8742FF731209/Documents/
This is the simplest command you can run to get your path to .realm file. You will see the .realm file after all your read and write operations are completed.
Or
You can you open source openSim, alternative of simpholders to access your app’s documents directory directly from your menu bar
If you are using the default Realm DB in simulator:
po Realm().configuration.fileURL
Updated answer to the newest Realm:
For Android:
checkout stetho and https://github.com/uPhyca/stetho-realm
Video tutorial here: https://www.youtube.com/watch?v=9pFJz5VexRw
For IOS (Swift)
Either:
debugPrint("Path to realm file: " + realm.configuration.fileURL!.absoluteString)
or
Step 1: Have a constant called dev somewhere. Let's say Constant file
public class Constants {
public static var dev: Bool = true
}
Step 2: Create another class called RealmFunctions.swift
import RealmSwift
func realmAndPath() -> Realm {
if Constants.dev {
// location of my desktop
let testRealmURL = NSURL(fileURLWithPath: "/Users/#####/Desktop/TestRealm.realm")
return try! Realm(fileURL: testRealmURL)
} else {
return try! Realm()
}
}
Step 3: finally in your view controller:
let realm = realmAndPath()

If you are getting 'Enter Encryption Key' dialog box error:
I am using Swift 2.1 with Realm 0.96.2 and was getting this error when trying to open the database file:
'default' could not be opened. It may be encrypted, or it isn't in a
compatible file format. If you know the file is encrypted, you can
manually enter its encryption key to open it.
Found that using the pre-release version of the Realm Browser 0.96 fixed the issue:

2020: Realm file on iOS Real device (Not simulator)
Starts from the menu bar at the top then follow the sequence below: -
Window
Devices and Simulators
Select Device
At the bottom find the title (INSTALLED APPS)
Note: Scroll down or enlarge the Devices and simulators pop up window to see the list of installed apps.
Select Your app.
Tap the gear button (It's located at the bottom of the apps list)
Download Container
Choose location to save it.
Right click on the downloaded file
Show Package contents
AppData
That's it from there you can access Your Realm files depending on your configuration. For example if you saved in Documents or Library folders simply open it to see your realms.
First, I acknowledge that this is an Android thread but it is the first search result for this issue in general.
To open the most recently created Xcode Simulator Realm db in Realm Browser you can use this script in Automator or type it all in at the terminal. By using Automator, I have one-click access to my current realm.
cd ~/Library/Developer/CoreSimulator/Devices/
cd `ls -t | head -n 1`/data/Containers/Data/Application
cd `ls -t | head -n 1`/Documents
open -a 'Realm Browser' ./default.realm
Install Realm Browser.
In Automator, click New, select Run Shell Script, paste in code, change Realm Db name, Click Run to test, save file somewhere convenient for quick click access.
I don't know where I found this tip the first time but this thread reminded me how I was accessing my live data in the past.
Just for your App is on the iOS Simulator
Enter
console.log (Realm.defaultPath)
in the code eg: App.js
I have taken this one step further.
I have created a swift file called RealmFunctions and in it, I have created this function
import RealmSwift
func realmAndPath() -> Realm {
if dev {
// location of my desktop
return try! Realm(path: "/Users/slynch/Desktop/TestRealm.realm")
} else {
return try! Realm()
}
}
Now in my main view controller, I have a global boolean variable called dev
var dev: Bool = true // when in development mode
var dev: Bool = false // when I want to run on my device or upload to app stor.
Now, all I have to do in my code is
let realm = realmAndPath()
So when in development mode, I can find my realm database on my desktop and can open in Realm Browser.
I found my realm file by issuing this command in Terminal:
sudo find / -name "*.realm".
Hope this helps!
For those using React Native and using the default realm:
Realm.defaultPath
In Swift
func getFilePath() -> URL? {
let realm = try! Realm()
return realm.configuration.fileURL
}
As previously was mentioned you can use next approaches to find file location
//code
Realm.Configuration.defaultConfiguration.fileURL
//lldb
(lldb) po Realm.Configuration.defaultConfiguration.fileURL
or you can manually find it:
//Simulator
/Users/<username>/Library/Developer/CoreSimulator/Devices/<simulator-uuid>/data/Containers/Data/Application/<application-uuid>/Documents/
//for example
/Users/alex/Library/Developer/CoreSimulator/Devices/E1D084B0-CD97-41B4-871F-E131CA33F635/data/Containers/Data/Application/373721C7-2381-4E3D-9ABC-2147F748322F/Documents/
//iPhone (download a copy)
Xcode -> Window -> Devices and Simulators -> Devices -> <select device and app> -> App container actions -> Download Container... -> <selectfolder and navigate to it (.xcappdata)> -> Right Click -> Show Package Consents -> AppData -> Documents
*Please note that if you set file name for realm and it has some other extension than .realm RealmStudio does not open it by default
To get the DB path for iOS, the simplest way is to:
Launch your app in a simulator
Pause it at any time in the debugger
Go to the console (where you have (lldb)) and type: po RLMRealm.defaultRealmPath
Tada...you have the path to your realm database
The correct (lldb) command is: Realm.Configuration.defaultConfiguration.path.
If you are trying to find your realm file from real iOS device
Worked for me in Xcode 12
Steps -
In Xcode, go to Window -> Devices and Simulators
Select your device from the left side list
Select your app name under the Installed apps section
Now, highlight your app name and click on the gear icon below it
from the dropdown select the Download Container option
Select the location where you want to save the file
Right-click on the file which you just saved and select Show Package Contents
Inside the App Data folder navigate to the folder where you saved your file.
Under Tools -> Android Device Monitor
And under File Explorer. Search for the apps. And the file is under data/data.
The correct lldb command for Xcode 7, Swift 2.2+ is po Realm.Configuration.defaultConfiguration.path!
Swift 2.3 solution
Easier solution that won't break with Realm updates
let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
print("App Path: \(dirPaths)")
The .realm file should be inside "Documents"
all the steps for android and ios can be found on the official realm website:
https://support.realm.io/support/solutions/articles/36000064525-how-do-i-locate-realm-files-on-a-device-or-simulator-
Although the question itself is for iOS, the title is pretty generic as such that it got me here. So, I have felt the need to share a solution for Windows here.
In dotnet C#, use realm.Config.DatabasePath to see where the realm file is located. If not set differently, then it is C:\Users\<username>\Documents\default.realm along with default.realm.management folder and default.realm.lock
To set a new path, adapt this code (folders must exists, or gives error)
var realm = Realm.GetInstance(new RealmConfiguration(optionalPath: "C:/myproject/myrealm/myproject.realm" ));
Hi I installed QLite Pro but Im unable to connect to a local SQLite file db how can I do this?
The fields to fill are:
Name:
Host: requeire
UserName:
PassWord:
Database:
Port:
At the end I solved this by using the program DB Browser for SQLite, I also tried the Firefox plugin but this one is better.
You can't! Sequel Pro is only for MySQL databases.
Same problem here, i couldn't make it work.
So I downloaded this firefox plugin: https://addons.mozilla.org/en-US/firefox/addon/sqlite-manager/ which works fine.
Here's a small guide on how to open a sqlite database from a app in the iPhone simulator
Run your application on simulator (so that the database file will be copied to your application's documents folder (don't bother if you don't know exactly what it means))
Run the SQLite Manager plugin in Firefox (Tools -> SQLite Manager)
Open the database (You can find the file by navigating: /Libraries/ApplicationSupport/iPhone Simulator/User/Applications/(*number)/Documents
*number is some sequence of hexadecimal numbers identifying current application bundle - you must just find the proper folder (it will contain .app)
It is also possible with database on device, but first you must download application's documents folder to some place on your computer. You can download the folder by going in Xcode -> Organizer, then select your Device and Summary Tab, then under the Applications list find your application, click the triangle |> to expand it, then click the arrow on the right to download the application's documents folder.

i am working on an android app which stores data in sqlite db i want to be able to access the data that is currently stored in the emulator. How do i go about connecting to it and perform sql operations.
Open a terminal window
Get a list of AVD devices by entering: adb devices
If your terminal can't find the adb command then have a look at this post for OSX or Windows.
Start a shell connection to your AVD by entering: adb -s emulator-xxxx shell
Browse to the databases location: cd data/data/your.package.name/databases
Type sqlite3 xxxxx.db
For SQLite shell instructions see Command Line Shell For SQLite
There is an example on that link about "sqlite command in adb"
In the eclipse, go in to FileExplorer, here you will find three root folders: here go in to
1.data
2.go in to data folder again
3. here you will find all the package names of the applications.
4. once you find your projects particular package, click on it.
5.you will see a folder called 'databases'
6.in that folder you will get the sqlite db file.
7.in order to pull it out of the emulator, just click on it and on the
top right corner you will find 3 icons: one to delete, one to pull a file from device and the other to push file in the device.
8. after selecting the db file, click on the icon that says 'pull a file from the device'.
Thats it mate ...cheers.
