Swift UIView subclass that loads itself from a companion NIB for widget development.
This is a Swift port of the technique covered in An Update on Nested Nib Loading by Yang Meyer (@yangmeyer).
If your class extends this class, you can set a UIView in a Storyboard or Nib file with your custom class and it will load a similarly named .xib file. For example, if you build MyView.xib and MyView.swift, set the custom class in Interface Builder to MyView.swift and it will load the NIB at runtime.
As a bonus, with Xcode 6, if you make your subclass @IBDesignable the view will render in Interface Builder!
For a working example, see edelabar/AutoLayoutTester. There's a more in-depth article coming soon.
This project uses nameOfClass.swift from indieSoftware/INSwift, thanks to Sven Korset for sharing, and of course, thanks to Yang Meyer for writing his original article.
