This page gives a nice example of what you might want to use:
http://stackoverflow.com/questions/24022479/how-would-i-create-a-uialertview-in-swift
You'll also want to look at the UIAlertController class reference or tutorials. If you want to do something when the user clears the alert, add a handler as the example states. Don't forget to store some kind of flag somewhere to suppress the alert on subsequent launches, unless you want this to appear each and every time the app opens.
You could also do this without an alert, by making your storyboard's entry point a view that segues to the rest of your app, but I believe an alert can offer different styles that have more visual impact? I could be wrong there.
