Flutter Run not working, Error launching application on iPhone

Question

I have updated the flutter version recently. after that flutter run is not working on iPhone. I am using android studio. run button on the android studio also not working for iPhone but simulators are working fine.

I am getting the following error. I have set the runner schema to release. still no luck.

"Error launching application on Raj iPhone."

Flutter version.

Flutter (Channel master, 1.24.0-8.0.pre.374, on Mac OS X 10.15.7 19H2 darwin-x64, locale en-GB)

I am not getting any additional errors. so i run flutter run -verbose i got the following info

#0 throwToolExit (package:flutter_tools/src/base/common.dart:10:3) #1 RunCommand.runCommand (package:flutter_tools/src/commands/run.dart:618:7) #2 FlutterCommand.verifyThenRunCommand (package:flutter_tools/src/runner/flutter_command.dart:1119:12) #3 FlutterCommand.run.

I have done flutter clean and checked again. still same issue.

Thanks

Have you opened the project through xcode and registered your iphone? Try to compile at least once directly from xcode to the iphone. — Luiz Filipe Medeira

In flutter/packages/flutter_tools/lib/src/ios/devices.dart, find the following code block:

_logger.printTrace('Application launched on the device. Waiting for observatory port.');
Uri localUri;
try {
  localUri = await observatoryDiscovery.uri.timeout(const Duration(seconds: 30));
} on TimeoutException {
  await observatoryDiscovery.cancel();
}

Increase the timeout to a bigger number, for example, 60 seconds fixed it for me:

localUri = await observatoryDiscovery.uri.timeout(const Duration(seconds: 60));

Also, remove the cached binaries to force snapshot regeneration:

rm /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.stamp /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.snapshot

In addition to this, you'll also need to force snapshot regeneration of flutter_tools, otherwise the changes you make to the dart code won't be applied. To do this you can run

rm /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.stamp /{$PATH_TO_FLUTTER_DIRECTORY}/bin/cache/flutter_tools.snapshot

. Source: github.com/flutter/flutter/tree/master/packages/…

Delete or Clear directory `~/Library/Develope/Xcode/iOS\ DeviceSupport/` is not recommended.

In my case, that is the flutter sdk bundled command ios-deploy (version 1.11.2-beta.1) issue. It find the wrong path of ~/Library/Developer/Xcode/iOS\ DeviceSupport/[iOS_Version_ARCH]/Symbols.

First check your ios-deploy version: __PATH_TO_YOUR_Flutter_SDK_/bin/cache/artifacts/ios-deploy/ios-deploy --version

Replace it with to current newest version 1.12.1.

git clone https://github.com/ios-control/ios-deploy.git
cd ios-deploy/ 
git checkout 1.12.1

## build it 
xcodebuild -project ios-deploy.xcodeproj -list
xcodebuild -project ios-deploy.xcodeproj -scheme ios-deploy

## get the built output path
xcodebuild -project ios-deploy.xcodeproj -scheme ios-deploy -showBuildSettings | grep BUILD_DIR  

## or use Xcode to build
open ios-deploy.xcodeproj  ## Build project with key: ⌘ + B

## check the output file
~/Library/Developer/Xcode/DerivedData/ios-deploy-[xxxxx]/Build/Products/Debug/ios-deploy  --version 

## replace the one in flutter sdk
cp ~/Library/Developer/Xcode/DerivedData/ios-deploy-[xxxxx]/Build/Products/Debug/ios-deploy __PATH_TO_YOUR_Flutter_SDK_/bin/cache/artifacts/ios-deploy/

Run your flutter project again with Android studio or Visual Studio Code or flutter run again. Finally succeeded.
