cmd/gomobile: support Catalyst and Apple Silicon #63

waylybaye · 2021-01-29T14:49:15Z

This PR is derived from #45 .

I changed the build process and it will create 3 frameworks for ios, simulator and catalyst. Every framework has a fat library contains both arm64 and x86_64 (except ios that only needs arm64).

Finally create one xcframework from all 3 fat frameworks and this xcframework contains every platform and architecture.

create one framework for all targets: ios, simulator and catalyst, every framework contains at least one arch library, and combine all framework into one xcframework

I'm happy to see this moving along, and think considering targets and architectures separately (as opposed to just treating catalyst as a new architecture as I had) is a much more elegant approach! And great to see Apple Silicon support added. 🎉

I've built my Sample.xcframework from this branch it it works on the target/architecture combos I've tested it quickly on: my old x86_64 mac with both simulator and catalyst, and my arm64 iPhone. Seems to work as expected. 👍

As far as tests, TestBindIOS fails now, but that's expected and should be a quick fix of updating the templates. I also have the TestBindWithGoModules tests failing. And finally TestIOSBuild is failing too, but that was already the case as mentioned in #45 (comment). I'm not sure how much effort should be placed towards these tests given they are failing already, but it would be very nice to get this helpful PR merged in. 🙂

Would this PR make .xcframeworks built by gomobile compatible with Swift Package Manager (SPM)? If so, my team is very excited for this to move forward!

I’m trying to use this fork with a replace directive in my project’s go.mod file, and it fails with an error:

Go 1.16 on macOS 11.3 beta, using Xcode 12.4 on an Intel MB Pro.

Edit: I forked this fork and rebased on golang/mobile@master and it worked! ydnar#1

Edit 2: it was trivial to add macOS support to gomobile in this fork, which enables the framework to be packaged and distributed via Swift Package Manager:

This is a pretty exciting and important PR, any idea when it will get merged?

Currently, if I try to install it manually, I get this strange error when I run gomobile bind:

When this PR will be merged ?

Add support for macOS (non-Catalyst) and Catalyst targets. The compiled library is packaged into a "fat" XCFramework file (as opposed to a Framework), which includes binaries for iOS, macOS, MacCatalyst (iOS on macOS), and iOS Simulator targets, for amd64 and arm64 architectures. The generated XCFramework file is suitable for distribution as a binary Swift Package Manager package: https://developer.apple.com/documentation/swift_packages/distributing_binary_frameworks_as_swift_packages This change is based on earlier work: #45 #63 Fixes golang/go#36856 Change-Id: Iabe535183c7215c68838d6c8f31618d8bceefdcf GitHub-Last-Rev: 623f8f3 GitHub-Pull-Request: #65 Reviewed-on: https://go-review.googlesource.com/c/mobile/+/310949 Reviewed-by: Hyang-Ah Hana Kim <hyangah@gmail.com> Reviewed-by: Hajime Hoshi <hajimehoshi@gmail.com> Trust: Hyang-Ah Hana Kim <hyangah@gmail.com> Trust: Hajime Hoshi <hajimehoshi@gmail.com> Run-TryBot: Hyang-Ah Hana Kim <hyangah@gmail.com> TryBot-Result: Go Bot <gobot@golang.org>
