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.

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

  2. 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/

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

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
