Error launching application on iphone

iOS Observatory not discovered after 30 seconds. Error launching application on iPhone

I’m unable to debug a freshly created app on physical iOS devices when pubspec dependencies reach a certain size, because it causes the «waiting for observatory port» step to timeout after 30 seconds.

Devices tested: iPhone 12, iPhone 12 Pro

iOS versions tested: 14.7.1, 14.5

The app runs properly on emulator but not on ios real device. How do I fix this issue?

I have encountered the same issue and following this process has fixed the problem for me on 14.7.1 and 14.8:

If it still doesn’t work you could try increasing the observatory timeout (the default appears to be 30 seconds):

I’m not 100% sure why this problem appears inconsistently, but there is a lot of related discussion at the following link: https://github.com/flutter/flutter/issues/72161

Try updating your Xcode and MacOS to the latest versions.

Then upgrade your packages:

And update your podfile:

Then clean and run:

I hope this will help 🙂

My problem was solved in this way:

That deleted whatever messed up configuration was causing the problem.

If you are running the Flutter project from VS Code you may not be getting all of the error information. You get more error logs if you run Flutter from the command line:

As per the logs you are using old cloud_firestore library Please use cloud_firestore-0.13.0+1 instead of cloud_firestore-0.12.11

Needs to enable Xcode developer mode. Make sure the Xcode license agreement is signed by either opening Xcode once and confirming or running sudo xcodebuild -license from the command line. For more details refer below link

This might help you,

then try to run again

Try removing the following line from ios/Podfile , which I added by following the suggestion in https://firebase.flutter.dev/docs/overview/#improve-ios-build-times.

This solution may help you, Please check the imports, it’s an error for me I changed my import like this.

I also had this problem sometimes, It happens if u change your project in android studios and go to the next Project, I recommend u close android studio and ios simulator and start the project again.

I import package ‘package:http/http.dart’ and get this error, when I removed this package dependency, this error gone.

For beginners: (tested on XCODE 12.0.1) open Xcode—> Open a project or file —> go to the flutter app path/ios directory—> open —> Runner and follow steps in attached link

I deleted this configuration item, success!

I’ve been having this problem a lot as well on my Mac M1. Initially it builds and runs fine but as soon as you start adding packages this error starts happening. I tried Olle Kyrychenko solution above and it didn’t work until I opened the project in Xcode, went to runner -> Info -> Configurations and changed the debug from Pods.debug to Debug (the first dropdown called runner i left as none, the second dropdown with a target I changed to debug). I did the same for release.

I would follow Olle Kyrychenko’s solution above first though

Flutter : Could not build the precompiled application for the device. Error launching application on iPhone

I can’t run my flutter project on an IOS device.

This is what I got after flutter run. I can’t understand why. Please have a look at the error below and tell me how to fix this.

What can I do to fix this problem? Please give me a command line or sth. Please help me. I am looking forward to hearing from you. Thank you.

If you want to simulate it immediately rather than taking care of the IDE issue generally, go to Tools -> Flutter -> Open iOS module in Xcode. But for a further solution, do a Flutter Clean, and remove the simulator from Xcode -> Window -> Devices and Simulators -> Simulators -> right click on your iOS simulator and click delete. Then add a new simulator from the bottom left corner “+” button in the same Devices and Simulators page you are on. Re run your app in flutter and it should be working.

Yes, I also got into this after upgrading to ios 14. So, first, add this to you podfile:

and also run: flutter upgrade

For me, these 2 things fixed the problem.

I just faced the same problem. IOS logs are not correctly described like Android. So try to follow the instruction below its work for me.

1. Run current code in Android Emulator. I have found that in Android logs show some of my dependencies syntaxes were deprecated (For me is flutter_svg)
2. I have changed the version of the flutter_svg version to ^0.19.0. You need to fix all the deprecated syntax of your run log.
3. Try to run in Android Emulator now it’s work for me.
4. Try to run in IOS Emulator. (First time it’s not working so I close IDE and reopen again and run) In this case flutter clean should sort your problem.

This works for my problem.

If you previously followed the FlutterFire steps here: https://firebase.flutter.dev/docs/overview#improve-ios-build-times then it is time to disable the pre-compiled version of Firestore stuff and let Xcode compile it from scratch.

In the file ios/Podfile comment this line:

Run your app and it should work now.

What worked for me was a combination of 4 steps:

Step 1, modify Podfile

and add the following (iOS platform must match):

Step 2, switch Flutter channel to master and upgrade Flutter

Step 3, Upgrade dependencies

1. Are you on M1 mac machine ?

From your error log, I see below:

which seem to indicate it’s not an issue with Flutter, but with cocoapods. See this similar issue and a workaround to resolve this.

This issue is already fixed in Flutter and merged in master. You may switch to latest master and try again to see if it works or still get same issue.

Also a note, when you post the logs, please put in a formatted text in triple quotes as I’ve done in your original comment, for better readability.

Flutter: Try this

1. Delete the Podfile , Podfile.lock , Pods folder , Runner.xcworkspace , Flutter.framwork(in ios/Flutter folder)
2. flutter clean
3. flutter build ios

Trust me, I search for over 5 hours, tried every solution I cound find on internet. And only one work:

1. Delete the Podfile, Podfile.lock, Pods folder
2. flutter clean
3. cd ios
4. pod deintegrate ( this way pod will not reinstall the old libray )
5. cd ../
6. flutter run

Most of the solution don’t include step 4, so that why even you clean and reinstall pod, it still behave the same.

If you are using Flutter, in your pubspec.yaml file make sure that your dependencies are installed below the cupertino icons line with correct indentation or it’ll throw an error.

Make your day happy thanks buddy for the help.

MacOS catalina has permission issues on pre installed ruby and rails.

rbenv is best version control thing. You need to install this tool by using terminal:

Open your terminal and type these commands:

And then run these commands:
