A declaration cannot be both 'final' and 'dynamic' error in Swift 1.2

Question

The declaration of value below

import Foundation

class AAA: NSObject {
    func test2() {
        self.dynamicType
    }
}
extension AAA {
    stat         


        

Answer 1

You can mark it as private to prevent this error. If you want to expose it, you can wrap it in a public function:

extension AAA {

    private static let value = 111

    public func getDatValue() -> Int {
        return AAA.value
    }    
}

In my case, I only referenced the property in the extension itself, so there was no need to expose it.
