What is Swiftify?

When Apple rolled out Swift back in 2014, Objective-C was set to be replaced. Even nowadays, however, there are plenty of apps and projects that still 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 is designed to automate much of the conversion process, handling the task of replacing syntax while letting you focus on other aspects of migrating your project to Swift. As the name suggests, the service can be accessed directly from Xcode. You can access it from the Editor menu, where you have the option of converting a selection of code or a whole file. You can also copy Objective-C code and paste it as Swift. It's also possible to convert files directly from Finder without booting up Xcode. Simply select one or more files and start the conversion from the context menu. Finally, the Advanced Project Converter app is designed to help you manage an entire project. It lets you explore it from a dedicated UI and select files to be converted. Processed items are automatically added to the project file. The app is included in Swiftify for Xcode, but it can only be used with a Cloud subscription or Pay As You Go plan credits.

Review Summary

Generated using AI from real user reviews

Swiftify is a capable tool that reliably converts Objective-C code to Swift and saves development time for most users. The majority of reviews are positive, with users praising its ease of use, time savings, and working output across conversion projects. Many note it handles standard cases well and that the Xcode extension integration is useful. Several users mention it's particularly valuable for migrating legacy codebases at scale.

The main criticisms centre on two areas. First, output quality isn't perfect—users consistently note that converted code still requires manual review and tweaking, especially for complex code, memory pointers, C integrations, and nullability handling. Second, and more frequently raised, is pricing. Multiple reviewers call the subscription model overpriced, particularly for one-time conversions or smaller jobs, with some suggesting open-source alternatives offer comparable results. A few report occasional request failures that still consume subscription credits.

Overall, Swiftify works well for what it does and justifies its cost if you're doing substantial Objective-C-to-Swift migration work. It's less compelling as a one-off purchase or for teams with tight budgets.
