How to exit app and return to home screen in iOS 8 using Swift programming

Question

I\'m trying to programmatically return to the home screen in an iOS8 App using Swift. I want to continue the application running in the background though. Any ideas on how

Answer 1

Swift 4:

UIControl().sendAction(#selector(NSXPCConnection.suspend),
                       to: UIApplication.shared, for: nil)

Edit: It's worth mentioning that in iOS 12 there's a bug that will prevent network connectivity if the app is brought back from background after sending the suspend action.
