Class to make UserDefaults get/set easier in Swift

Question

I created the following class to ease UserDefaults get/set within my Swift project.

class MyDefaults {
    enum Key: String, CaseIterable {
        case email // String
        case password // String
    }
    static private let defaults = UserDefaults.standard
    static func set(_ value: Any?, key: Key) { // to set value using enum key
        defaults.setValue(value, forKey: key.rawValue)
    }
    static func get(key: Key) -> Any? { // get value using enum key
        return defaults.value(forKey: key.rawValue)
    }
    static func hasValue(key: Key) -> Bool { // check value if exist or nil
        return defaults.value(forKey: key.rawValue) != nil
    }
    static func removeAll() { // remove all stored values
        for key in Key.allCases {
            defaults.removeObject(forKey: key.rawValue)
        }
    }
}

The aim is to use the class as follows:

let email = MyDefaults.get(key: .email)
MyDefaults.set(email, key: .email)

Note: I used static in class method in order to use it as type i.s.o. class instance.

I'm not sure about the static for the property 'defaults'. Xcode complaints if I omit it.

Is above code correct and/or is there something I missed?
