Catalyst Support + M1

[parrots]

There's a long thread (https://github.com/mapbox/mapbox-gl-native-ios/issues/117) on the legacy v6 Mapbox SDK about getting Catalyst support, and it seems that while this new SDK supports metal so Catalyst is possible, something is misconfigured with the shipped framework preventing it from working. Not sure if this is an M1 specific issue as I do not have an Intel Mac to also test with, but the build error leads me to guess that.

Environment

• Xcode version: 13.0 RC
• Maps SDK Version: 10 RC 8

Observed behavior and steps to reproduce

• Download RC 8, open the Examples app xcproj (not workspace)
• Add RC 8 as a dependency to the project via SPM
• Open the build settings for the Examples target, and on the General tab check the "Mac" support checkbox
• (Make sure your signing settings are properly configured here, might get errors about signing profile)
• Set your destination to "My Mac" at the top of Xcode, then try to build and run

Expected behavior

Should build and run locally

Observed behavior

Does not build. If you're on an M1 Mac building, you'll get the following error:

ld: warning: ignoring file /Users/parrots/Library/Developer/Xcode/DerivedData/Examples-anjbxfhnfyknmlfwaklruslpjpmc/Build/Products/Debug-maccatalyst/MapboxCoreMaps.framework/MapboxCoreMaps, building for Mac Catalyst-arm64 but attempting to link with file built for Mac Catalyst-x86_64

If you try to build and run using the "My Mac (Rosetta)" you get an odd code signing error (although obviously we shouldn't need to use Rosetta).

Thanks for reporting this issue. While we do support building for the iOS platform with an M1 Mac / Apple Silicon, we do not support Catalyst at this time.

Out of the box on an intel macbook pro building an app for catalyst with macbox as a dependecy gives only the two following errors.

This happens in a generated file, Forcing the types to Turf.Polygon allows it to build. Then, when trying to run on a mac locally the remaining issue is related to codesigning:

Any updates on this ?

Is there a workaround for this issue? After installing the SDK via SPM, my app won't build for Mac at all. If I want to build a MacCatalyst version of my app without any Mapbox-related feature today, would it be possible to exclude the SDK as a dependency?

Catalyst build was fixed in https://github.com/mapbox/mapbox-maps-ios/commit/51f2527bda4e20792a6ff108114e3aa093ceae65
