How to click a button programmatically?

Question

I have 2 view controllers which should be swapped according to userinput. So, I want to switch the views programatically based on the input I get from a text file.

To fire an event programmatically you need to call sendActionsForControlEvent

button.sendActionsForControlEvents(.TouchUpInside)

Swift 3

button.sendActions(for: .touchUpInside)
