Custom Views Quickstart add view programmatically

[githubhero]

Not a real issue, but you can avoid this line:

var imageView: CaptionableImageView!

because you can instantiate the view on the fly, even multiple times (eg. in a loop), by declaring it locally. There's no need to make it a class member.
