How NSAnimationContext completionHandler work with Swift Language

i couldn't port this to swift, rest of NSAnimationContext straight forward. 

[[NSAnimationContext currentContext] setCompletionHandler:^(void) {
    //doSomething here...
}];

in docs it says var completionHandler: (() -> Void)! it did not mean anything to me. Thank you.

() -> Void is the signature for a Swift closure that takes no parameters and returns nothing. Use it much like you would an ObjC block:

NSAnimationContext.currentContext().completionHandler = {
    // do something here
}

Note that since it's declared as a property, you should set it like one -- ObjC getter/setter pairs don't translate to Swift.
