NSInteger score = 556 NSString *name = BOOL loggedIn = NO Variables and constants Create a variable If you can already program in Swift and want to get up to speed with Objective-C as quickly as possible, I have just the book for you: Objective-C for Swift Developers. Where necessary I have added small clarification notes to give you more understanding. In all instances, Objective-C code is shown on the left and the equivalent Swift code on the right. Well, that's exactly what you'll find below: a Rosetta stone of Apple development, demonstrating variables, collections, functions, classes, and more. If you encounter any problems, we would appreciate bug reports: simply paste the original code (and ideally the wrong result produced by Oxidizer) into an email and send it to or post a bug report on Talk.If you're moving from Objective-C to Swift, or perhaps from Swift to Objective-C, it can be useful to have a quick start guide showing equivalent code samples in both languages. While Oxidizer's support is extensive, it is always possible that there will be some code constructs it does not handle yet. ![]() You can also try Oxidizer online, at /elements/oxidizer Reporting Conversion Issues The following conversions are supported: ↓ From / To → Also note that conversion to Go is severely limited, since many core constructs of the other langages (such as even Classes) cannot be expressed in Go. In particular, Delphi code can only be converted to Oxygene, and conversion from Go is not available. Oxidizer does not currently support converting from and to all language combinations. As in the previous example, Oxidizer will not magically get rid of the Delphi RTL or VCL APIs your code uses, but it will adjust the core language syntax for the differences between Delphi and Oxygene. Oxidizer is also useful for migrating Delphi code to Oxygene. NET, Cocoa or Sugar equivalent to use that same code on different platforms. Using " Paste Java as Oxygene" will convert the algorithm into proper Oxygene code, you just might have to replace any Java-platform-specific APIs the code used with their. For example, you might have an algorithm implemented in Java and want to use that in your. However, Oxidizer can also be useful for converting code between different platforms. Note that Oxidizing from Swift will not "undo" Swifty-fied API names on the Cocoa platform to their proper Objective-C level names, since Oxidizer processes only the language syntax. NET), the Java language (for, well, Java), and Objective-C (for Cocoa), chances are the converted code will work right away, as Elements of course uses the exact same classes and APIs as those languages, on the respective platform. The Import feature lets you select one or more code files from disk and import them into your project as new files, translating them in the process.įor platform-specific code written in C# (for.The Paste As feature lets you paste code from your clipboard straight into your current code file, and converts it on the fly. ![]() Oxidizer is integrated into the IDEs and can be invoked in one of two This makes it easy to reuse code snippets or even whole classes found online, or to convert pieces of code from an existing project to Elements. Elements includes Oxidizer, a powerful tool that can convert code from C#, Java, Objective-C and Delphi code to Oxygene, C#, Swift, Java and Go.
