Xcode wait for animation to finish before executing next task - swift

Question

I have a layer that moves up when I swipe up and then the same layer moves down when I swipe down.
When I swipe up, I don’t want the user to be able to swipe down to activate that animation until the swipe up animation is complete and vice-versa.
How do I accomplish this? I’ve tried disabling the swipe gesture using “isEnabled” but no dice. Some other similar questions have answers that are from very long ago and the syntax is very different. I’m using the latest version of xcode.

This issue could be solved by adding boolean variable, IF Statement along with a DispatchQueue function to prevent another animation from occurring until the current animation has finished.
import UIKit
var animation_active = false
let animation_duration = 2 //For easy maintenance
func swipe_down() {
if animation_active == false {
animation_active == true
//Animation code goes here. Variable 'animation_active' should be used when performing the animation for easy matinence
DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(animation_duration), execute: {
animation_active = false
})
}
}
func swipe_up() { //This is exactly the same as swipe_up. Yet it will prevent the swipe animation from occuring when the swipe down animation is occuruing thanks to the variable 'animation_active'
if animation_active == false {
animation_active == true
//Animation code goes here. Variable 'animation_active' should be used when performing the animation for easy matinence
DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(animation_duration), execute: {
animation_active = false
})
}
}
