Yes, your approach of creating an IBOutlet from the storyboard and referencing it using self.myInput.text is a standard way of accessing this field in Swift.

As for whether to use self.myInput vs. myInput, I prefer to always write self because it is very obvious that the variable is a property and will probably be changed in many different places (opposed to a local var). Also, once you have self there, you don't have to worry about introducing local vars with the same name or making changes if you copy and paste a block of code into a closure that requires self.
