Write code to use function AsyncAfter and afterDelay to delay or wait time in Swift?
(1)Here in first function we use function using AsyncAfter. Below is the block of code after a time delay by using asyncAfter:-
let DelayInseconds = 4.0
DispatchQueue.main.asyncAfter(deadline: .now() + DelayInseconds)
{
print("This message display after 4 seconds")
// Put any custom code here
}
(2)Here we call a function after a Wait time. Here function is call after certain period of time:-
let DelayInseconds = 4.0
perform(#selector(delayedFunction), with: nil, afterDelay: DelayInseconds)
@objc func delayedFunction()
{
print("This message display after 4 seconds")
}
