marzipanify is a tool I created to statically convert an iOS app built for the iOS Simulator to macOS. It means you can continue working on and building your existing iOS app from its existing project, using the existing iOS SDK, and just run the tool against the Simulator build to create a functioning Mac app. As a bonus, marzipanify will yell at you when you’re linking against a framework or library that doesn’t currently exist in the iOSMac runtime. It trivializes the process so you can focus on adapting your app rather than managing a build environment.
Curious to see what people will come up with before the expected Marzipan-for-developers announcement during this year’s WWDC. Having said that, I’m still partially horrified at the potential flood of poor Marzipan apps coming to the Mac, and how they’ll affect developers actually catering to the feature set and strengths of MacOS.
