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

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.
