How do I write dispatch_after GCD in Swift 3, 4, and 5?
In Swift 2, I was able to use dispatch_after to delay an action using grand central dispatch:
var 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
})
But this no longer seems to compile since Swift 3. What is the preferred way to write this in modern Swift?
