Why is iOS Simulator not running? - ios-simulator

When I try to run my program, iOS Simulator goes black and displays this error:
Unable to boot the iOS Simulator.
When I click OK, Xcode shows this error:
Unable to run app in Simulator. An error was encountered while running (Domain = NSMachErrorDomain, Code = -300)
How I can I make it run again?

You probably are running two different instances of the iOS Simulator.
Clean the project. (CMD+SHIFT+K)
Quit Xcode.
Quit all instances of iOS Simulator.
Restart the computer.
Log in.
Make sure no instances of iOS Simulator are running (I had a wrong version set to Open At Login)
Run your project, and let Xcode open the right Simulator.

If you've recently updated XCODE and possibly have more than one installation you may need to specify which XCode is being used via the command line.
sudo xcode-select -s /Applications/Xcode6-Beta4.app/Contents/Developer/

Just Reset Content and Settings worked for me. Also clean the project once and build.

SpringBoard failed to launch application with error: -3

I'm getting an warning as 'SpringBoard failed to launch application with error: -3'. This happens when trying to run application in Xcode 5.
Finally...found solution!
Solution 1 : Just quit Simulator and clean Xcode. The fresh build will not show this Alert again. The possible reason for this might be switching between 64-bit simulator and 32-bit simulator.
Solution 2 : If the problem still persists then delete the App from Simulator and re-run the code. This will work since the app contents are freshly loaded.
Springboard (also known as Home Screen) is the standard application that manages the iOS home screen.
Also, these may be bug of Xcode 5.0.2. I haven't encountered any such error in Xcode 5.1 (Beta) version.
just close the simulator, clean it your project, built it again, and launch again. Its work on me.
It also works to clean your code and then go to iOS Simulator -> Reset Content and Settings. Just an alternative if you don't want to close and reopen your Simulator (mine takes forever to quit and reopen)
Just had the same problem.
After trying what evanhutomo failed for me, I tried a slight variation.
Install 6.1 simulator
Run in 6.1 simulator
When it fails you should be dropped on the spring board
Delete the application.
Try building again
Hope this helps.
Deleting the app from the simulator and then rebuilding and running helped me solve the problem.
I tried the other solutions here, but none worked. From another SO answer I tried setting App Support/iPhone Simulator directory recursively to 777 permissions.
$sudo chmod -R 777 "~/Library/Application Support/iPhone Simulator/"
I'm not recommending this, just saying it took care of the problem for me!

iOS Simulator failed to install the application

I have created a Cordova 2.1.0 app, It ran fine for the first 2-3 times. But now when I am trying to run it through terminal it is giving me the following error.I didn't change anything.

any help would be appreciated.
Thanks
Solved the problem
Deleting contents of ~/Library/Application Support/iPhone Simulator and re-run the project solved this problem.
or you can simply reset content and setting of the simulator.
Try manually launch the iOS Simulator and from the "iOS Simulator" menu, click "Reset content and settings", then close and rebuild your app.
My solution is:
From menu, iOS Simulator, Reset Content and Settings.
Close XCode 5.0: close project and close it from Dock and re-open the project and launch again, like in Windows :)
I tried everything mentioned above and nothing worked. My problem was iOS 7 specific. I was finally able to resolve the issue by assigning a non-empty value to Bundle versions string, short (CFBundleShortVersionString) in the -Info.plist file. Looks like iOS 7 doesn't like an empty value for the build number. I had a script that auto increments the bundle number by 1 every time I build the project so this field was empty. I just assigned a dummy value there to get it working.
You can also remove the app from the simulator.
This worked for me in iOS6.1

I copied a folder into XCode 4.6.2 with the name "Resources". When XCode asked, I created the folder references for any added folders.
Every time I did this, I would have to goto the Derived applications directory, and delete the build directory for my project to get it working again.
Solution: Do not copy a folder by reference into XCode with the name "Resources". Rename it to something else other than Resources.
Very annoying error.
just reset your simulator and re-run your project
Unfortunately none of these solutions solved my problem. I did everything, even restarting my mac but it was still failing. What actually did solve my problem was to go to the Organizer and delete the Derived Data and Snapshots.
Had the same problem after installing XCode 5. Had no iOS 6.1 Sim or SDK. Obtained these. Tried to run the App up under the iOS6.1 Sim and go the failed to install message. Having read through all of the above posts, I decided to simply remove the App from the Simulator and re-istall, re-run from the project window and that solved it for me.
I tried ALL these things and more including reinstalling Xcode 5 and nuking every xcode and simulator preference/application support file with no luck.
Then for the hell of it, I CHANGED my short bundle version string (it already had a value, it was not empty), and it fired right up.
3 hours gone but yeah
All the answers I looked for do not work for me!.
Finally
The only way to make it work is as follows
1.Check the version of titanium being used for the project in tiapp.xml
2.right click the prject in the project explorer window.
3.Select Properties
4.Choose project build path. Select Titanium Mobile SDk all versions of 3.* Tick all of them.
5.Now click apply and re run the project.
None of the above worked for me, I finally compared my info.plist to another project and found that I had somehow deleted the "Executable File = ${EXECUTABLE_NAME}" key/value pair, replacing it fixed the problem for me.
This error occurs on iOS 7.0 if you leave the "Build" empty.
Enter a build number!
What worked for me was to simply delete an old version of the app, which was made in a prior version of Xcode (likely 4, now running 5) from the simulator (tap-hold, jiggle, x).
I encountered this problem while trying to create a build for Facebook application approval. I found that for some reason, when I used the following command line:
xcodebuild -arch i386 -sdk iphonesimulator7.1 -scheme Mana -configuration Release
the files didn't end up in [project root]/build/... (as the instructions on Facebook suggest), but in ~/Library/Developer/Xcode/DerivedData/[app name + unique identifier]/Build/Products.
I'm not sure exactly what's going on here (anyone who knows more please enlighten me!) but I was able to run the files in the DerivedData directory on the simulator. Hopefully they'll also work for Facebook!
I tried everything mentioned above and nothing worked.
Finally the only way to make it work was unsetting DYLD_INSERT_LIBRARIES=/usr/lib/libimckit.dylib
How I did this:
Open terminal and typing "sudo vi /etc/launchd.conf"
Changing
"setenv DYLD_INSERT_LIBRARIES /usr/lib/libimckit.dylib"
to
"unsetenv DYLD_INSERT_LIBRARIES /usr/lib/libimckit.dylib"
Save changes
Reboot your system

On Mavericks 10.9.5 using Xcode Version 6.0.1 (6A317) with an iOS SDK supporting 8.0 originally had Simulators all version 8 all getting this error. All the advice above was not working for me. So went to Xcode->Preferences->Downloads and saw as installable (but not yot installed) in the Components section were iOS Simulators 7.1 and/or 7.0. Went ahead and installed the 7.1 Simulators and got extra designations on the Product->Destination list Simulators of version 8.0 and 7.1, and using the 8.0 still had the same error, but the 7.1 Simulators all worked.

App gives off __dyld_dyld_fatal_error on simulator, WORKING and FINE on device

I was scouring over stackoverflow and somehow unable to find the answer to my problem. My app builds and compiles just fine, but when i try to run it on the simulator, it throws a __dyld_dyld_fatal_error(). However, when i try to run it on an iOS device, everything is smooth. On a side note, I've have just updated my XCode version to XCode 4.2 to support iOS5
It turns out that I had to reset the settings on my simulator before having to run it without any glitches, and made sure of the correct version of iOS that the application has to run on.

Iphone simulator hangs while installing apps

I am using snow leopard, xcode 3.22, i first had this issue when i was using os 4 beta, i have removed the xcode software from my system and reinstalled. I can't get any app to load in the simulator, the app starts to install in the simulator then nothing, I can install the app to my device, but i can run anything in the simulator it just hangs, i am not sure what to do
any idea?
I had the same problem and it drove me nuts. I finally figured it out.
Make sure that "/Library/Application Support/iPhone Simulator" is owned by your user id and that it is also writable by you. All the subfolders should also be owned and be writable by you.
Once I changed ownership of "/Library/Application Support/iPhone Simulator" to me everything worked.
I've had a similar problem. The simulator launches but stays on a blank screen. Then when I press "stop" in Xcode it doesn't stop. I have to force quit Xcode. I've tried many solutions including reinstalling Xcode.
Ultimately, the only thing that worked was changing the debugger from LLDB to GDB in the scheme. I don't know why this works.

iPhone app crashes from Finder

I've written an iPhone app and only tested it with the simulator as I don't have an actual iPhone. If I Build and Go, I can see the app running. But if I go to Finder and then open it through the project's build folder, it just crashes immediately. Does anyone know the reason for this?
It crashes because double-clicking it causes Mac OS X to try and run it as a Mac app. It's got the same structure as a Mac app, and it's an x86 binary, so why not? But the iPhone app tries to dynamically link UIKit, fails to do so, and crashes. The simulator sets up the iPhone app's environment so that the linking succeeds. You could probably do this at the command line with careful use of environment variables, but the Finder doesn't do so.
Finder won't launch the simulator correctly. XCode is the only supported way to launch the simulator as far as I know.
So Tom, if I wanted to send that binary to a friend, what are the instructions for opening it?
