Xcode 6.1 (6A1052c): Swift - can't observe read-only properties

Classification:Other Bug Reproducible:Always
 
Summary:
I’ve subclassed AVPlayerViewController for a tech demo and I’m trying to get the right position to add overlays. I figured that using the `readyForDisplay` property would be the best bet, so I set about using a Swift observer:

    override var readyForDisplay: Bool {
        didSet {
            
        }
    }

This generates an error - saying it can’t be observed because it can’t change. Then what good is this property? Should I poll the thing like an animal???

Steps to Reproduce:
Given

Expected Results:
Ability to observe read-only properties so that I can do cool stuff afterwards

Actual Results:
Given

Regression:
N/A

Notes:
I’ll now scour the docs and probably end up using some kind of notification subscription … like an animal.
