xcode - Disable app nap in Swift

Question

How do I disable app nap in Swift? Im new to programming and I am building a timer(just for practice), and I am afraid app nap will break my timer.

Answer 1

I found that this solution works in Swift as well.

Create a class or global variable

var activity: NSObjectProtocol?

And assign it after which App Nap will be disabled

activity = NSProcessInfo().beginActivityWithOptions(NSActivityOptions.UserInitiated, reason: "Good Reason")
