Hi there,

I'm trying to get the app running on iOS. So far I used https://rogchap.com/2020/09/14/running-go-code-on-ios-and-android/ to compile libcwtch-go for iOS and then tried to convince Xcode that it puts it all together. You'll have to run it on a Mac - I used the following versions:

go 1.16.3
Android Studio 4.1.1
XCode Version 12.5 (12E262)

git clone gogs@git.openprivacy.ca:ineiti/flutter_app
cd flutter_app
make ios

And then open the project with Android Studio and do the following:

choose an iPhone in the device list
click the Run button

It starts to compile, and after 2-3 minutes, I get the following error in the app:

======== Exception caught by widgets library =======================================================
The following ArgumentError was thrown attaching to the render tree:
Invalid argument(s): Failed to load dynamic library (dlopen(cwtch.a, 1): no suitable image found.  Did find:
	/Users/.../Library/Developer/CoreSimulator/Devices/3D7064C5-8392-4BF8-9C49-FE6898022AE6/data/Containers/Bundle/Application/CC43A084-5DF6-4931-95AC-854D28134174/Runner.app/Frameworks/cwtch.a: no matching architecture in universal wrapper

What is strange is, that lipo reports x86_64 and armv7 as architectures:

lipo -info /Users/.../cwtch.a 
Architectures in the fat file: /Users/.../cwtch.a are: x86_64 arm64

I tried all kinds of arguments, asked Google, tried running it on an ipad simulation, but it refuses to run.

Any idea would be very welcome :)

Hi @ineiti thanks for diving into this!

I think the best next step is probably to open a PR in https://git.openprivacy.ca/flutter/libcwtch-go to include the iOS build steps in the makefile - that will give us a common reference to the build steps and we can start working out where the archiecture issue is being introduced. It will also give us a path towards eventual automation.

(Doing a quick check I did fine this discussion in dart: https://github.com/dart-lang/sdk/issues/39231 which has some additional considerations regarding the M1 and also code signing which may or may not be applicable)

OK, added the PR for flutter/libcwtch-go#39 and one for flutter/flutter_app#78

Both are draft-PRs, the libcwtch-go specifically because it doesn't work yet in flutter_app!

For the link about dart-lang, I think you're one step ahead of me, and this will only bite me later. I'm not concerned yet with app-signing, even though this is known to be tricky with iOS. I have bad memories about this ;) Or perhaps it is app-signing?

I'll try the simple example from scratch, and then try to take it from there.
