Add2App [Option A&B] with plugins failed to build because plugins was built without full bitcode #48092

nailgilaziev · 2020-01-02T22:37:31Z

This is a next step of an issue described here #47930 and all preparation steps is the same.
But now before building .xcframework just add to my_flutter module some plugin dependencies.
I added most popular shared_preferences plugin to pubspec.yaml and added example code to main.dart file.
Next

flutter build ios-framework --output=../host_ios/embed/ --xcframework --no-universal

produce

App.framework
Flutter.xcframework
FlutterPluginRegistrant.xcframework
shared_preferences.xcframework

Applying them to xcode pbxproj -> build -> error

ld: bitcode bundle could not be generated because '/Users/n/Library/Developer/Xcode/DerivedData/host_ios-bnbwehcmdjzqgydxspnsnfifvdyh/Build/Intermediates.noindex/ArchiveIntermediates/host_ios/BuildProductsPath/Release-iphoneos/shared_preferences.framework/shared_preferences' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '/Users/n/Library/Developer/Xcode/DerivedData/host_ios-bnbwehcmdjzqgydxspnsnfifvdyh/Build/Intermediates.noindex/ArchiveIntermediates/host_ios/BuildProductsPath/Release-iphoneos/shared_preferences.framework/shared_preferences' for architecture arm64

I checked this situation with another plugin - path_provider - result the same.

If I try to disable bitcode I get another error:

with this logs:
IDEDistribution.critical.log

IDEDistribution.verbose.log

The text was updated successfully, but these errors were encountered:

This issue was on
Flutter (Channel master, v1.13.6-pre.48, on Mac OS X 10.15.2 19C57, locale en-RU)
upgraded ~ 3 hour ago, but after (when I writing this issue) new version released, so...

additionally I upgraded to currently latest:

Flutter 1.13.7-pre.8 • channel master • https://github.com/flutter/flutter.git
Framework • revision dc99d61e5d (2 hours ago) • 2020-01-02 13:03:01 -0800
Engine • revision fa05d367ad
Tools • Dart 2.8.0 (build 2.8.0-dev.0.0 b52d264f5b)

and repeat test:
Result the same - bitcode error
PS now building frameworks generate App.xcframework, not the App.framework as before.

nailgilaziev · 2020-01-02T23:48:48Z

You doesn’t apply severe label.
Any workaround exist for this problem? If yes - I will apply it for publishing my app to the TestFlight.

jmagman · 2020-01-07T22:40:25Z

I need to try this, I'm not sure what's going on and don't have a workaround at the moment.

Magsumov2 · 2020-01-08T12:58:45Z

Hello! @jmagman , please tell me - When will it be fixed? I meet the same issue and I can not release application because of this error! thanks

nailgilaziev · 2020-01-09T13:35:22Z

@jmagman , I tried to add flutter module to app via Option A - cocoapods script, recommended way
But when archive this error occurs:

bitcode bundle could not be generated because '/Users/n/pubios/my_flutter/.ios/Flutter/engine/Flutter.framework/Flutter' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '/Users/n/pubios/my_flutter/.ios/Flutter/engine/Flutter.framework/Flutter' for architecture armv7

nailgilaziev · 2020-01-09T14:19:08Z

to make sure I'm doing everything right and to provide more information for you I do everything from scratch with latest flutter version:

[✓] Flutter (Channel master, v1.13.8-pre.58, on Mac OS X 10.15.2 19C57, locale en-RU)
[✓] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[✓] Xcode - develop for iOS and macOS (Xcode 11.3)
[✓] Android Studio (version 3.5)

I create new flutter module
flutter create --template module my_flutter
create new xcode project and then configure pod file and reopen .xcworkspace

with simplest flutter module(no pub dependencies) everything compiles and successfully uploads to AppStore.
But when I add dependency to flutter module and try to build and upload again I meet the error on archive:

bitcode bundle could not be generated because ... was built without full bitcode....

jmagman · 2020-01-14T03:10:46Z

Need integration tests that not just build the host app, but archive and validate it, too.

Xcode project settings > Build Settings > Embed Frameworks and remove FlutterPluginRegistratant.framework (or xcframework). Keep it in Link Binary With Libraries.

This is a static framework, not a dynamic one...
I will update the docs. Hopefully this unblocks you.

Plugin framework was built without full bitcode.

ld: bitcode bundle could not be generated because '/Users/n/Library/Developer/Xcode/DerivedData/host_ios-bnbwehcmdjzqgydxspnsnfifvdyh/Build/Intermediates.noindex/ArchiveIntermediates/host_ios/BuildProductsPath/Release-iphoneos/shared_preferences.framework/shared_preferences' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '/Users/n/Library/Developer/Xcode/DerivedData/host_ios-bnbwehcmdjzqgydxspnsnfifvdyh/Build/Intermediates.noindex/ArchiveIntermediates/host_ios/BuildProductsPath/Release-iphoneos/shared_preferences.framework/shared_preferences' for architecture arm64

I believe this one is because the plugins are being built instead of archived, and so aren't being created with bitcode. I'm about to put out a pull request to fix this one.

Flutter was built without full bitcode

bitcode bundle could not be generated because '/Users/n/pubios/my_flutter/.ios/Flutter/engine/Flutter.framework/Flutter' was built without full bitcode. All frameworks and dylibs for bitcode must be generated from Xcode Archive or Install build file '/Users/n/pubios/my_flutter/.ios/Flutter/engine/Flutter.framework/Flutter' for architecture armv7

I believe this could happen if flutter build --debug was last run in the module and there's a debug version of Flutter at the vendored_framework path. The release version should be re-copied when the [CP-User] Run Flutter Build Script build phase runs in the host app, though. I need to look into this one more.
In the meantime, try running flutter build --release in your Flutter module, then re-try pod install from your host app.

nailgilaziev · 2020-01-14T10:46:36Z

@jmagman, Does you(or team) need any tests or clarifications from me?
This issue is blocking and no other ways to workaround it.
Adding flutter module with some pub dependencies to host app currently not working at all.
Does not work in either the stable or master channel. neither option A nor B
Please help.

jmagman · 2020-01-14T18:57:07Z

@nailgilaziev Did you try my suggestions above?

For option A (CocoaPods) try running flutter build ios --release in the Flutter module.

For option B (generating frameworks) disable bitcode in your host app, and remove FlutterPluginRegistratant.framework (or xcframework) from the Embed Frameworks build phase. It's a static framework and so should be linked on and not embedded. Depending on what plugins you have, you may also need to do the same for them. Run:

$ grep -riI "static_framework" .ios/Pods

to see which podspecs (CocoaPods metadata per plugin) should also be removed.

nailgilaziev · 2020-01-15T13:19:31Z

@jmagman , sorry, I didn't saw you message when writing "help" :) my bad. I will try it now and get feedback today

nailgilaziev · 2020-01-15T15:05:26Z

yeah, option B with excluded FlutterPluginRegistratant.framework (or xcframework) from Embed Frameworks phase is working!
Thanks! I already released long-awaited release!

jmagman · 2020-01-17T20:47:19Z

Added the warning here:
https://flutter.dev/docs/development/add-to-app/ios/project-setup#embed-the-frameworks

isacjunior · 2020-02-07T19:55:29Z

@jmagman I believe that is important to add in website(docs) to recommend run flutter build before pod install for these reasons above and for another reason that I'll explain below:

When I create a new flutter module, flutter script will create a .ios folder and after I run pod install, the script inside podhelper.rb will create an App.framework used in Pods only with arch x86_64.

To reproduce:

flutter create --template=module example
cd ios_app
pod install

Because app_framework_dylib doesn't exist will create App.framework.

`echo "static const int Moo = 88;" | xcrun clang -x c -dynamiclib -o "#{app_framework_dylib}" -`

When I use File to show more details, this is output:

App: Mach-O 64-bit dynamically linked shared library x86_64

For resolving this, run build with the mode that you need before, for example:

flutter build ios --release --no-codesign

When I use File now, these are output:

App: Mach-O universal binary with 2 architectures: [arm_v7:Mach-O dynamically linked shared library arm_v7] [arm64]
App (for architecture armv7):	Mach-O dynamically linked shared library arm_v7
App (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

Question:
For a particular reason, I need architecture x86_64 when I create the framework with Release mode, it possible? Some workaround?

Flutter is not supported in the simulator (x86_64) in release mode. See #11754.

Hello, just wanted to drop a quick note thanking you for the detail in this issue and the related PR. We are not flutter users, but came across similar iOS build errors in our app that links against frameworks from a different project. The frameworks are delivered after being built (not archived), so the fix to build with BITCODE_GENERATION_MODE=bitcode was very helpful for us. Thank you!

We're developing the plugin which is added to the app where this is reproducible. You can find the app project in here in case you want to reproduce this.

As described in our repo issue, using Release build configuration does the trick as workaround to be able to run the app on iOS device. Is this still supposed to be like that?

Cheers

jmagman · 2021-03-19T01:43:05Z

@uerceg adjust/flutter_sdk#42 sounds like it's a normal Flutter app trying to consume your plugin, not necessarily add-to-app related. I just ran your sample app on a phone against Flutter stable and it built and launched fine in debug mode, I don't see any bitcode related warnings.

It's running:

2021-03-18 18:38:55.220440-0700 Runner[1752:1764709] 	[Adjust]w: SANDBOX: Adjust is running in Sandbox mode. Use this setting for testing. Don't forget to set the environment to `production` before publishing
...

It doesn't even have bitcode enabled (which aligns with the default in a flutter created app):

I recommend you file a new issue since it doesn't look related to add-to-app.
