Ambiguous type error

Question

I'm trying to recompile SwiftyUserDefaults ( https://github.com/radex/SwiftyUserDefaults ) to add Carthage support, but when I try to compile, I see the following error

Ambiguous proxy type name in NSUserDefaults

for the following code

public func ?= (proxy: NSUserDefaults.Proxy, @autoclosure expr: () -> Any) {
    if !proxy.defaults.hasKey(proxy.key) {
        proxy.defaults[proxy.key] = expr()
    }
}

and

"Proxies" are ambiguous for type searches in this context

for

public subscript(key: String) -> Proxy {
    return Proxy(self, key)
}

As I understand it, the problem is with the Proxy class, which is built into the extension.

public extension NSUserDefaults {
    class Proxy {
        private let defaults: NSUserDefaults
        private let key: String

        private init(_ defaults: NSUserDefaults, _ key: String) {
            self.defaults = defaults
            self.key = key
        }

        // MARK: Getters

        public var object: NSObject? {
            return defaults.objectForKey(key) as? NSObject
        }

        // ..................................       

    }
}

I was looking for documentation, but there is no reference to the fact that the class can be used in the extension.

Is it correct?
