Scheduling a Closure Expression in Swift

I'd like to be able to schedule a closure to be run at either an absolute or relative time in the future. I see that I can use

to schedule a selector to be called later, but this is not what I want. I would prefer to see something like this:

let timer = NSTimer.scheduleWithTimeInterval(
ti: NSTimerInterval(1.0),
action: {
// do something

Is there a built-in way to do something like this in Swift?


I've now come across
which seems to be more in line with what I want, but I'm open to other ideas.

dispatch_after should be a fine solution since there are no block based NSTimer methods.

Alternatively you could use (or create) a simple block based NSTimer category (or an extension in Swift):
