Swift compiler often but-not-always crashes on async/await block using optional ObjC protocol method with callback #79319
Description
Description
I need to call optional methods from an objective-c protocol and this method delivers results on a callback which is mapped into async in Swift.
This will often crash the Swift compiler and the fix seems to be to change the code, recompile, change the code back and recompile.
Reproduction
static func downloadImageData(_ provider: GitHostingProvider, owner: String) async throws -> Data? {
guard let determine = provider.determineAvatarImageUrl else {
return nil
}
let url = try await determine(owner)
return try await Data.downloadUrl(url)
}@protocol GitHostingProvider <NSObject>
@optional
-(void)determineAvatarImageUrlForOwner:(NSString *)owner
completion:(void (^)(NSURL* _Nullable, NSError* _Nullable))block;
