Not all concurrency annotations added to Objective-C are visible in the Swift translation #74629

Open mattmassicotte opened 1 week ago

mattmassicotte commented 1 week ago

Motivation

I've discovered that if I add concurrency-related annotations to Objective-C signatures, the compiler understands them, but Xcode does not make them visible. Here's an example:

+ (void)jetPackConfiguration:(void (NS_SWIFT_SENDABLE ^)(void))completionHandler NS_SWIFT_DISABLE_ASYNC;

Note the lack of @Sendable

class func jetPackConfiguration(_ completionHandler: @escaping () -> Void)

Now it is entirely possible this is not a compiler issue. I'm just guessing because of this:

Proposed solution

I'd like to see the fully annotated function siguature!

Is this reproducible for you with VS Code? If it's Xcode only, it might require filing an FB I'm afraid.

Yeah, it could be this is an Xcode issue. But, reason I assumed that may not be the case is because it took a compiler change to expose global actors in this same place.
