As for Swift至于斯威夫特
Swift 5.3 was comming with Xcode 12 and default for new project. Swift 5.3 随 Xcode 12 一起提供，并且是新项目的默认版本。 However was Swift 4x still compiling back then.然而，当时 Swift 4x 仍在编译。 Didnt try this recently as there is no point or advantages from using an old language version.最近没有尝试这个，因为使用旧语言版本没有任何意义或优势。 In fact you need to write way more boilerplate code if you stick with Swift 4.事实上，如果你坚持使用 Swift 4，你需要编写更多样板代码。
