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?

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.

Here is the link to the documentation from developer.apple.com.

Swift should be `UIApplication.sharedApplication().idleTimerDisabled = true` – Doug Feb 04 '15 at 22:49

where to add this line? I don't have AppDelegate.swift as I'm using react-native – Pradnyanand Milind Pohare Nov 12 '19 at 18:32
@PradnyanandMilindPohare you can add it wherever you want, just make sure this line it's executed – Mellao Aug 05 '20 at 07:05

For Swift 3.0 here are two options depending on where you want to invoke the code:

Inside AppDelegate.swift:

application.idleTimerDisabled = true

Outside AppDelegate.swift:

UIApplication.shared().isIdleTimerDisabled = true

You can use my little lib Insomnia (Swift 3, iOS 9+) - another nice feature is that you can prevent from sleeping only when charging.

The idleTimerDisabled soultion is okay but you have to remember to set it to false afterwards.

If you have more advanced case you can use our small project: ScreenSleepManager or if it's just about particular ViewControllers - use Insomnia as pointed earlier. Manual dealing with idleTimerDisabled almost always caused me some issues (like forgot to re-set to false or handle multiple (nested) modules trying to set it).
