The Swift Programming Language (Swift 5.7) - Apps Dissecteda parameter’s type instead of in front of a parameter’s name. • Updated the discussion of the @noescape and @autoclosure attributes in the Escaping Closures and Autoclosures sections and the Attributes can contain string literals. • Added the Escaping Closures section with information about the @noescape attribute. - Updated the Declaration Attributes and Conditional Compilation Block sections with @autoclosure is now an attribute of the parameter declaration, not its type. There’s also a new @noescape parameter declaration attribute. For more information, see Declaration Attributes. - Type methods0 码力 | 1040 页 | 10.90 MB | 2 年前3
