If you’re moving your app’s interface from under the keyboard when it appears, you’re probably doing the following: 1. Get a reference to the relevant text field in the UITextFieldDelegate‘s textFieldDidBeginEditing method. 2. Listen to a relevant keyboard notification (possibly…
What is the difference between these three enigmatic types? A sometimes confusing topic, let’s get it straight. UPDATE: Things have changed in Swift 3! This post has been updated for Swift 3 here. You probably know Swift is a type-safe…
