I have taken help from this answer and Apple's Developer guide . You can achieve it by setting observor over applicationDidBecomeActive method of Appdelegate using NotificationCenter . Below is the code to achieve your task .

Put the following code in the viewDidLoad of your ViewController .

NotificationCenter.default.addObserver(self,selector: #selector(doSomeThing), name: .UIApplicationDidBecomeActive, object: nil)

Then when ever didBecomeActive is called from Appdelegate this function will be called ... So you can put the action you want to perform in this function

func doSomeThing(){

}

Also put the following code in the the viewDidDisappear of the same ViewController to remove the observer otherwise your app will crash

 NotificationCenter.default.removeObserver(self,name: .UIApplicationDidBecomeActive,object: nil)

Thanks! really helped me out. – MoniXx Mar 28 '17 at 12:01 — MoniXx, Mar 28 '17 at 12:01
