How to prevent screen lock on my application with swift on iOS

Question

How can I prevent screen lock only when using Navigation?

Waze has the option to do that, how can I do this in my App?

Answer 1

Use this:

Objective-C:

[[UIApplication sharedApplication] setIdleTimerDisabled: YES];

Swift (legacy):

UIApplication.sharedApplication().idleTimerDisabled = true

Swift 3 and above:

UIApplication.shared.isIdleTimerDisabled = true

Make sure to import UIKit.
