这将是您导入任何 Objective-C 代码所需要的唯一的头文件,以便您的 Swift 代码可以访问。然后,在项目构建设置中找到 Swift Compiler - Code Generation 部分。将您的桥接头文件的路径添加到 Objective-C Bridging Header 旁边,路径从项目根文件夹开始。它应该是:MyProject/
Write and run Swift code easily and professionally! Swifty Compiler app is a great way to get an algorithm or method down on the go and make sure it works. Yo…
The test cases are used heavily to cover all code, but still got some situations are not well handled, those code that can crash the REPL will be added as test cases sequentially, the codes in swift-compiler-crashes will eventually merged to test case when the compiler is stable enough....
SwiftFormat is a code library and command-line tool for reformatting Swift code on macOS, Linux or Windows.SwiftFormat goes above and beyond what you might expect from a code formatter. In addition to adjusting white space it can insert or remove implicit self, remove redundant parentheses, ...
So the code for the action to our alert view becomes so: let action = UIAlertAction(title: "Next", style: UIAlertActionStyle.Default, handler: {[weak self] (paramAction:UIAlertAction!) in if let textFields = self!.controller?.textFields{ let theTextFields = textFields as [UIText...
statement it stops generating that code and the Release build runs as expected. I suspect that this is a failure in the compiler’s mandatory optimisation phases. Swift is unusual in that some optimisations have to run for the code to be correct, and in this case it seems that the optimisa...
Do we have separate optimisation levels for Swift and Objective-C code? What do they mean, what are they influence on? How do two compilers in the mixed Swift/ObjC project work together optimising the code? What specifically the compiler does for each optimisation level? To answer these ...

I think that properly designing the models or entities of a domain is one of the biggest contributors into good code, and the lack of it makes everything way harder than it should be. Thankfully Swift is a great language that allows us to express almost everything we need to in a very...
Swift Code Blocks A code block is a group of statements (zero or more) that is enclosed in curly braces { }. For example, if true { // start of block let sum = 2+3 print("Result is \(sum)") } // end of block Here, the code block consists two statements: let sum = 2+3...
