This inspired from some of Apple's UIKit controls that come as part of Xcode Interface builder such as UIPickerView. When I drag a UIPickerView into my scene, you get a placeholder image that says "Cupertino, San Francisco, Montainview, Palo Alto" etc. Those elements are not editable its just a nice placeholder that way you dont have this big blue square that says UIPickerView.
I have a UIView Class called ProgressTrackerView and I have a placeholder image of a progress tracker UI... is there a way I can see that placeholder image in Interface Builder but when I run my app... the actual prgress tracker with real data appears instead? Eventually, if we ship this as library for others to use, it would nice to have something there.
I looked into IBDesignables, however, IBDesignables fail to render UIImageViews with images, so thats not a viable solution.
