How to add app icon to project using Xcode 4.3.1

Question

How do I add an application icon to my project using Xcode 4.3.1?

Answer 1

Download Asset Catalog Creator Free from iTunes. All you have to do is select a base image, and the program will create all required iOS icon sizes for you and place them neatly in an .xcassets file, which you can simply drag into Xcode. Much easier than worrying about the sizes/resolutions of individual icons.
