Swift 基于闭包的类型擦除
networkService.loadData(from: T.requestURL) { data in do { try completionHandler 这可以通过创建擦除类型的类，例如 包装类 来完成： class AnyModelLoader<T>: ModelLoading { typealias CompletionHandler = ( Result<T>) -> Void private let loadingClosure: (CompletionHandler) -> Void init<L: ModelLoading >(loader: L) where L.Model == T { loadingClosure = loader.load } func load(completionHandler : CompletionHandler) { loadingClosure(completionHandler) } } 以上这种类型擦除技术，其实在 Swift 标准库中也很常用
