Sound overlaps with voiceover and AVFoundation player

Question

In my iOS app, I have a button which can play sound after clicking on it, however this button has a voiceover function at the same time. When I click on the button, both of the two sounds overlap.

You can use GCD to delay one of the processes.

DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
    self.functionToCall()
})

This will play your second sound 10 seconds later.
