The review of SE-0297: Concurrency Interoperability with Objective-C concluded yesterday.
The feedback was light but very positive, with some great questions and discussion in the thread. The core team has accepted the proposal, but agree with Ben Rimmington that optional completion handlers should imply
@discardableResult. The proposal is accepted with that change.
Thank you to the proposal author and to everyone who participated in the review, and happy holidays!
