Swift performSelector:withObject:afterDelay: is unavailable

Question

I have an app in Objective C that I'm transitioning to Swift. In Objective C, I have this method:

[self.view performSelector:@selector(someSelector) withObject:self afterDelay:0.1f];

I'm working with Swift and I can't figure out how to do this. I've tried:

self.view.performSelector(Selector("someSelector"), withObject: self, afterDelay: 0.1)

Here's the error that I get: 'performSelector' is unavailable: 'performSelector' methods are unavailable

What call would I use to call a method afterDelay?

UPDATE

Here's what I ended up with:

extension NSObject {

    func callSelectorAsync(selector: Selector, object: AnyObject?, delay: NSTimeInterval) -> NSTimer {

        let timer = NSTimer.scheduledTimerWithTimeInterval(delay, target: self, selector: selector, userInfo: object, repeats: false)
        return timer
    }

    func callSelector(selector: Selector, object: AnyObject?, delay: NSTimeInterval) {

        let delay = delay * Double(NSEC_PER_SEC)
        let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay))
        dispatch_after(time, dispatch_get_main_queue(), {
            NSThread.detachNewThreadSelector(selector, toTarget:self, withObject: object)
        })
    }
}

Answer 1

Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
    // your function here
}

Swift 3

DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(0.1)) {
    // your function here
}

Swift 2

let dispatchTime: dispatch_time_t = dispatch_time(DISPATCH_TIME_NOW, Int64(0.1 * Double(NSEC_PER_SEC))) 
dispatch_after(dispatchTime, dispatch_get_main_queue(), { 
    // your function here 
})
