Apple rolled out Swift in 2014 to replace Objective-C. There are still plenty of apps and projects that use Objective-C, and developers are faced with the prospect of either starting again from scratch or attempting to convert them to Swift. Swiftify for Xcode automates the conversion process, handling the task of replacing the syntax while letting you focus on the other aspects of project migration. As the name suggests, the service can be accessed directly from Xcode's Editor menu. You can convert a code selection or a whole file. You can paste Objective-C as Swift. It's also possible to convert files directly from Finder without booting up Xcode. Select the files and start the conversion from the context menu. Finally, the Advanced Project Converter app included in Swiftify for Xcode is designed to help you manage an entire project. It lets you explore the project in a dedicated UI and select files to be converted. Processed files are automatically added to the project.

Skim through traffic with highlighting by content type, status & source, or use powerful filtering tools to precisely match the messages that matter to you. Examine the URL, status, headers & body of each request or response, with inline explanations & docs from MDN. Dig into message bodies with highlighting & auto formatting for JSON, HTML, JS, hex and others, all using the power of Monaco, the editor from Visual Studio Code. Precisely match requests, jump to them when they appear, and edit anything: the target URL, method, headers or body. Manually respond directly to requests as they arrive, or pass them upstream, and pause & edit the real response on the way back. Step through HTTP traffic request by request, or manually mock endpoints and errors. Create rules to match requests and respond with your own content, to quickly prototype against new endpoints or services.
