As requested by @jmagman, I create this separate issue from #60424.

Steps to Reproduce

  1. run app from flutter run or Xcode 12
  2. disconnect app from debug session
  3. crash when re-launch app

Note: running app in simulator does not have above issue.

Logs

As it says, codesigning issue. This may not be a flutter issue though.

===============================================================================

Summary of issue as of 2020-09-7

The current solution based on ios-deploy 1.11.2 beta 1 will most likely be the stable solution when iOS 14 comes out this month.

Affected workflows

All Flutter apps built with a Debug Flutter build cannot be launched on iOS 14 physical devices from the device itself without a host computer. This includes launching via the home screen (springboard), deep linking, notifications etc. This is a new restriction from iOS 14 on apps' ability to set itself in debug mode in order to change the execution mode of newly JIT'ed code.

Full-Flutter - Solution

If you created your Flutter project via flutter create, you have a 'full-Flutter' project. To launch a debug build Flutter app, you can either

1- Launch via flutter run on Flutter master channel.
2- If you already have your desired flutter flags set (such as --local-engine, --target, --route, etc), you can also launch via Xcode with the iOS Xcode project at <your Flutter project root>/ios/Runner.xcworkspace.
3- Build and install a Profile/Release build of your Flutter app. You can then relaunch from home screen, notification etc from the device directly without a connected host.
4- If you already build your iOS app via flutter build ios --debug, you can also launch with ios-deploy 1.11.2 beta 1 and later via ios-deploy --noinstall --justlaunch --bundle <your Flutter project root>/ios/Debug-iphoneos/Runner.app.

Add-to-app - Solution

If you created your Flutter project via flutter create -t module and embedded the Flutter module inside your own host iOS app via Cocoapods or the module framework build via flutter build ios-framework, you have an 'add-to-app' project.

Your add-to-app project will crash starting in iOS 14 when you run your FlutterEngine if your Flutter module is a debug build.

To mitigate, you can either:

1- Re-launch your host iOS app from Xcode.
2- Embed a Profile/Release build of your Flutter module instead. You can then relaunch your host app and enter the Flutter screen from the home screen, notification etc from your device directly without a connected host.
3- Re-launch your host iOS app with ios-deploy 1.11.2 beta 1 and later via ios-deploy --noinstall --justlaunch --bundle <your iOS .app which embeds a Flutter module>. (Convenience feature request to allow --bundle_id to be specified instead of --bundle in ios-deploy).

Once launched, you can then enter your Flutter module's UI and flutter attach to debug and hot-reload as usual on Flutter master channel. Not #63893. You cannot flutter attach on iOS 14 if you're not on master channel. You must accept the local network permission dialog in order to flutter attach on iOS 14.

This question is same to mine.#60522
But it does not resolved. I am waiting too. In addition, It crashed not just at iOS 14, it can also crash at other iPhones,like ,iOS 12.5,ios13.5.1, and other version, this bug happened on flutter SDK 1.17.0,1.17.1,1.17.4, Lower version is ok!

Hi @PhantomRay
Can you please provide your flutter run --verbose
while reproducing the steps you described

does this behaviour occur with an "hello world" app?
Thank you

Hi @iapicca
The app can launch with flutter run. So it is a different scenario to what #60522 has mentioned

@TahaTesser I run project at Xcode,then it crashed. Here is the log about 'flutter run --verbose -d <device_name>', it crash on launch.

It happens when the iPhone is disconnected from the debug session, and then restart the app.

I don't think flutter run --verbose will do anything unless I miss some point here?

Hi @codeliu6572
I'm please follow up on this issue for your case
I agree with @PhantomRay, this issue might be a different scenario.

@PhantomRay I apologise I misinterpreted the disconnect reconnect part
(in my head somehow sounded like "minimise resume")
thanks for clarifying that
