Status:Open Resolved:
Product:Developer Tools Product Version:iOS 9.1
Classification:Serious Bug Reproducible:Always
 
Summary:
A VC that is a type-specific subclass of a type-generic class cannot override initWithCoder.

Example:
class GenericViewController<T>: UIViewController {}

class PurpleViewController: GenericViewController<Int> {
    required init?(coder aDecoder: NSCoder) {
        print("Hello")
        super.init(coder: aDecoder) // Value of type '_ -> _' has no member 'init'
    }
}

class BlueViewController: UIViewController {
    required init?(coder aDecoder: NSCoder) {
        print("Hello")
        super.init(coder: aDecoder)
    }
}

Steps to Reproduce:
1. Paste the code above in a playground or application
2. Error! Value of type '_ -> _' has no member 'init'

Expected Results:
I expect to be able to override initWithCoder for any UIVC subclass

Actual Results:
The compiler throws a error

Version:
iOS 9.1 & Xcode 7.1

Configuration:
All
