Tink is not supported on Apple Silicon for iOS

[sethfri]

Describe the bug:

In order for Tink to support Apple Silicon builds on iOS, it needs to be distributed as an XCFramework, Apple's new native binary format. Google will need to do the following:

• Update the objc/BUILD file to build an xcframework
• Host a tarball containing this xcframework
• Publish a new version of the podspec to CocoaPods using the vendored_frameworks property to point to the xcframework

What was the expected behavior?

Importing Tink via CocoaPods should pull in an XCFramework, which allows us to build our app for device and simulator on Apple Silicon

How can we reproduce the bug?

Add pod Tink to your Podfile, run pod install, and try to build your app on Apple Silicon

Provide your version information:

• Language: Obj-C / Swift
• Environment: iOS

@chuckx 👋🏻 Wanted to follow up on this. This didn't land by the end of April timeline from our last discussion. Is there a new target date for Apple Silicon and XCFramework support on iOS?

Hi @chuckx, following up on this

[chuckx]

FYI, I'm finalizing the XCFramework build process now. The last remaining step is integrating the symbol stripping step (since we're wrapping (Boring/Open)SSL, we need to make sure that symbols from that library aren't exposed, otherwise it can lead to symbol conflicts in projects that already include them).

This is the final blocker for releasing 1.7.0. So, as soon as I'm done, the release will be performed.

Hi @chuckx, are we still on track for end of June for the 1.7.0 release?

Hello, @chuckx any update on this. Using the latest version would be very helpful in simplifying our process a lot.

Thanks.

Checking to see if there's any progress on this.
