There already is a backdoor of sorts. This is one of the intended use cases for implicitly-unwrapped optionals. If you don't want to be hassled by DI, declare a property as T! type, and it will be implicitly initialized to nil, and trap if you try to use it as an unwrapped T without initializing it first. -Joe _______________________________________________ swift-evolution mailing list swift-evolution@swift.org https://lists.swift.org/mailman/listinfo/swift-evolution
