[swift-users] Swift 3 equivalent of dispatch_barrier_async

I tried searching github's swift-evolution for "dispatch_barrier_async",
but don't see a mention of it.

Can I migrate this directly to swift 3, or do I need a larger refactor
involving serial queues?


let myConcurrentQueue = DispatchQueue(label: "concurrentQ", attributes: .
dispatch_barrier_async(myConcurrentQueue) { ... }
