I have used Expo a few times successfully before, but for a few days now, I am unable to get into the Expo App. Whenever I open it, I see the Expo icon for a few seconds up to even minutes, and then it redirects me to the blue "Something went wrong" screen, as if I had tried to open an app.
But I didn't! It doesn't even let me scan a QR code, it just always shows this error. If I click the back button in the app, it simply terminates. I have ensured that it is the latest version and already reinstalled it once.
It seems like it somehow had locked itself onto an old, now non-existant server, and kept at it after reinstalling the app. Here is how I solved the problem:
In the metro bundler, choose connection type "Tunnel" and copy and send the URL to your phone. If you then click on it on your phone, it should redirect to the expo app. After that it got unstuck and I could finally use it normally with the QR code again!
The tools sometimes do get locked into this state.
Close and restart all components (Expo cli, browser tabs and clients) making sure to:
Kill any stray processes on the server (you need to check Activity Monitor / Process Explorer or similar depending on your platform)
Force quit all client devices and simulators using the correct method for each platform. To verify that the client process has actually been killed, check that the app splash screen is displayed for a short while when invoking it.
Clear the Expo cache when starting again: $ expo start --clear
I ran into the same issue. Solved it by going to the left sidebar in the Metro Bundler and sending a link via email!
I've tried many of the solutions and only one worked for me (which i found trying random things). I already had 'allow display over other apps' turned on (Android/OnePlus 6t) and didn't think it had anything to do with that. But I tried this...
Close the Expo app, go the the app settings and turn off 'allow display over other apps', open the expo app and [when prompted] turn on 'allow display over other apps' again.
That seems to work in my case - at least until the next time.

My app is using Firebase Analytics and I believe starting in iOS 13.2 started getting the errors described here: Why I get the console warning: [Process] kill() returned unexpected error 1 when I load a WKWebView in iOS13.2?
I guess it wasn't a big deal
Since I planned for my app to go live in January, I began bigger tests in physical devices. I noticed after a while the app started to behave erratically, specially after receiving a [general] Connection to daemon was invalidated error. This doesn't occur in the simulator
Searching the internet I found a post that describes the same problem: https://forums.developer.apple.com/thread/124306
In my case, only Firebase seems to be calling WKWebView, but every time I open the UIMenuController I get the error described in the console and the app appears to be missing inputs. This is specially troublesome with UIScrollViews, which my app uses a lot. The pinch gesture seems to work at will. On an iPhone 6s, the issue isn't as noticeable, on an iPad, it's like a 50% chance the pinch gesture will work properly
Outside of removing Firebase, is there a way to mitigate this issue?
1 June 2020: The console message still persists, however, I have seemed to resolve the UIScrollView issue by deactivating delaysContentTouches, now the pinch gesture seems to work most of the time
23 October 2020 If anyone notices their app starting to behave erratically with no apparent reason I HIGHLY suggest to test it on an iOS 13 physical device if possible. Seems that Apple removed the warning from iOS 14, but testing it on iOS 13 you can pin point the exact reason after the warning appears in the console
Upon further testing, I've reduced the view down to a dead-simple UI view with a single SwiftUI TextField and the 'Connection to daemon was invalidated' still appears after I type the first character into the field. Soon thereafter the app crashes with a sigAbort. (So I don't think the reason is the UITextView wrapper I was using in the previous post). Once the invalidated message appears the app is doomed to crash, not right away but soon thereafter.
I have no idea what causes the 'invalidate' message and a Google search seems to imply that no-one else does either. Some folks appear to have made (experimental?) changes to their UI that stops the message but it appears to be impossible to determine a definite cause. (and like before it only occurs on a real phone)
Same issue without using Firebase at all. What I did: Delete build folder and compile again. Issue does not appears again.
On Xcode:
Clean the Build Folder
This will delete all of the products and intermediate files in the build folder. To clean the build folder you can use the shortcut Command+Option+Shift+K or Menu Bar → Product → Hold Option Key → Clean build Folder.
On Flutter:
Just delete build folder.
i installed bluestacks on my windows 10 laptop (HP elitebook ) , it worked well the first time , i installed whatsapp on it ,it worked properly for few minitues messages started flowing but i couldnt get the chance to read them because my laptop frozes for seconds so i restarded it, the next time i started bluestacks after opening the laptop i found that it went back to initializing phase, i'm forever stuck there.
i'm not sure if it needs a good internet to initialize
for the second time?
if not , why it stucks in initializing , i tried multiple suggestions i found on internet (like compatibility solution) but didnt work out.
if there is nothing to do, how can i extract whatsapp database so i can read my chats on another device.
if i installed whatsapp on another device, i won't get the messages i recieved once on bluestack again,right?
please help me whatsapp chats are so important to me.
you can't able to restore those chats again
if you are using windows 10 directly download whats app to your lap directly from store or go to link https://www.whatsapp.com/download/
It runs just fine on the iPhone. When I select the Watch App Target, however, it simply won't run on the watch.
I don't get any errors or anything. I can see the app downloading on the Watch sometimes; when it does download, it deletes itself the moment the download is complete.
I've tried uninstalling the watch app and reinstalling via the Apple Watch app on the iPhone, and the same thing happens: it downloads and deletes itself before I can run it.
I've also reset the watch, reset Xcode, deleted the iOS app, and just about everything else I could possibly think off, but I'm starting to lose my mind.
The problem started happening when I (attempted to) set up the Watch Connectivity framework. I don't know if this is related. I've been unable to verify that WC is working properly as I can't open the app.
I've been lucky enough to get it to actually load on the watch only a few times since integrating WC framework, but even when I have, all I got was the loading screen for about a minute each time.
UPDATE:
I'm now seeing some consistent behavior.
I'm now able to debug my app by launching the watch app via Xcode. The app icon does not appear at all on the watch when this happens, however. (Weirdly enough, it shows the launch screen for a different watch app when launching.) So I can't run the app at all unless it is launched from Xcode.
Also, I am not able to download the app to the watch via the phone. I want to be able to run it outside of debug mode, and I can't. When I attempt to install it from the Apple Watch iOS9 app, the install begins, I see the icon on the watch as it downloads, and just as it finishes, it deletes itself from the watch before I can run it. This just keeps happening.
Please help!
Make sure your Apple Watch device ID is in your provisioning profile.
So, this kind of sucks as an answer, but I've had enough.
I decided to copy all of my code and storyboards into a new Xcode project. The Watch App now works exactly as it should. Hopefully Apple sorts out these bugs in an update.
I believe repairing the watch would help as well. I had the same problem before and the only thing which helped was repairing the watch.
I also have other issues debugging the watch app properly - see my question here Proper way to debug watchos2 app in XCode7
So I'm working on my Meteor project and all of a sudden everything stops working and my console reports that everything is 'undefined'. See screenshot. Why does this happen? Usually things will just randomly start working again after I reboot my machine or go get lunch.
This can happen if you have a hot code reload during when the page is loading from a previous hot code reload.
Your browser will eventually reconnect to the server, reconnect & refresh the page. In the case above it looks the the bit of Js that connects to the server doesn't get loaded to begin with (the DDP bit) so it doesn't behave as normal. If it reconnects it can fix it self by refreshing.
It's very hard to tell what exactly is causing it from the information you've given. I'd look at custom packages that replace core packages or some kind of of package you have that runs early on in your code that would stop the normal loading of a project.
If you're using meteor on windows there are a couple of bugs that do this too. I'm not sure how to get past those besides doing Ctrl+C to stop and then using meteor to start the project again.
By some mysterious reasons I got myself a jailbroken iPhone 3GS from a vendor whom I am finding difficult to track.
My task is to test out in app purchase functionality on it.
Currently it has iOS 5.0.1 with cydia installed.
No, it does not have Appsync.
I am installing my build through testflightapp API which works without issues with my app so far.
However when I initiate in app purchase, I don't get anything in response.products so far.
I have added productIDs and all in itunes-connect already, checked twice that they are fine, since 48 hours.
I tried testing with iPhone simulator 5.1, but all I got was no values from storekit. I would love to hear if there is any workaround with simulator.
Worked around this finally - deleted my app from itunes connect, re-added it.
It complained about name being already used.
I changed the language of name. And it worked.
Maybe, my prior app setup was right, but I had something else messed up.
In between, I rejected my app. That maybe one of the reason behind this issue.
Lesson?
Don't developer reject your app.
