build ios-framework simulator slices for profile/release

[jmagman]

Description

Generate an x86 simulator slice for profile and release for add-to-app flutter build ios-framework for plugins, App.framework, and plugin registrant framework. This matches profile and release Flutter.xcframework.

This lets users build in profile/release against the simulator in their host app, (even though it uses a Debug version of Flutter).

Hi @jmagman!

I am trying to build flutter app with the following command: flutter build ios-framework --xcframework

And even after this PR there is no simulator slice in App.xcframework, FlutterPluginRegistrant.xcframework in release/profile folders. How can I build it so that I can run it on simulator and device in release configuration?

[jmagman]

@Cr1xus I just tried is and I see:

Profile/App.xcframework/ios-x86_64-simulator
Profile/FlutterPluginRegistrant.xcframework/ios-x86_64-simulator

etc.

What version of Flutter are you on? #73378 is available in 1.26.0-12.0.pre which is currently the dev and beta channels.

@jmagman I am on latest stable (1.22.6). My bad, it is not on master channel. Thank you for checking.
When do you plan to release it?

At the moment I did a workaround by copying Debug(x86_64) architecture into Release .xcframework, but would be good to use it properly.

We release stable about once a quarter, stay tuned!

If that works, it's a good workaround. I would have thought you would also have needed to add ios-x86_64-simulator to the XCFramework's Info.plist (example Profile/App.xcframework/Info.plist) AvailableLibraries array, but if it works without it, that's great.

Yep, did that as well. Actually, wrote a script to do that. Copies x86_64 & substitutes Info.plist into Release .xcframework.

Got it, will be waiting.
