Hello, Does the proposal fixes the errors introduced by the latest May 9 snapshot ?
Since IUO are abolished (https://github.com/apple/swift-evolution/blob/master/proposals/0054-abolish-iuo.md) and pointer nullability is expressed using Optional (https://github.com/apple/swift-evolution/blob/master/proposals/0055-optional-unsafe-pointers.md), I get many errors as soon as I use libdispatch: let sem = dispatch_semaphore_create(0) dispatch_semaphore_wait(sem, …) // Error: Value of optional type not unwrapped dispatch_semaphore_signal(sem) // Error: Value of optional type not unwrapped let source = dispatch_source_create(…) dispatch_source_set_event_handler(source) { … } // Error: Value of optional type not unwrapped dispatch_source_set_cancel_handler(source) { … } // Error: Value of optional type not unwrapped dispatch_resume(source) // Error: Value of optional type not unwrapped Of course, it's easy to fix. Still, the fix is usually adding a bang (!), because most apps prefer crashing when dispatch_semaphore_create or dispatch_source_create fails. And if I don't mind using bangs when it's the best solution, I can't be happy to see bangs everywhere. In short: libdispatch is currently in its worst state ever :-) Cheers to all, Gwendal Roué > Le 11 mai 2016 à 06:39, Chris Lattner via swift-evolution > <swift-evolution@swift.org> a écrit : > > Hello Swift community, > > The review of "SE-0088: Modernize libdispatch for Swift 3 naming conventions" > begins now and runs through May 17.
