Summary:
ARC requires that names starting with init and then a non-lowercase character be initializer methods. A property named initValue violates this, resulting in an extra release due to ARC expecting the method to return a +1 value when it actually returns a +0 value.

Steps to Reproduce:
Run the following Swift code:
class MyThing: NSObject {
    dynamic var initValue: Int = 0
    dynamic var finalValue: Int = 0

    func save() {
        self.valueForKey("initValue")
    }
}

let thing = MyThing()
thing.save()

Expected Results:
The compiler should error that “initValue” is a bad name for a dynamic property, or should produce the output necessary to avoid a crash

Actual Results:
Segfault
