dispatch_after - GCD in Swift?

Question

I\'ve gone through the iBook from Apple, and couldn\'t find any definition of it:

Can someone explain the structure of dispatch_after?

d         


        

Answer 1

To execute a funtion or code after a delay use the next method

DispatchQueue.main.asyncAfter(deadline: .now() + 'secondsOfDelay') {
        your code here...
    }

Example - In this example the funtion getShowMovies will be executed after 1 second

DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
        self.getShowMovies()
    }
