Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

In reply to @rnapier, here's how to reduce the implicit optionals in your code: factor them out.
func result() -> A {
var result : A = dispatch_sync(resultQueue, {
return self.result
})
return result
}
func dispatch_sync<R> (queue: dispatch_queue_t, block: Void -> R ) -> R {
var result: R!
dispatch_sync(queue) {
