Answer 1

You can check if the respective device has an app is installed using:

// url = "example" (check the following image to understand)
let canOpen = UIApplication.sharedApplication().canOpenURL(NSURL(string: url as String)!)

Where url is pre configured (have a URL scheme registered for your app in your Info.plist)

So, if canOpen is true means that app is installed and you can open using:

UIApplication.sharedApplication().openURL(NSURL(string:url)!)
