Migrating an iOS app to macOS

Some time ago I published an iOS app called Mmmmmm, which lets the user to generate different wallpapers based on colors they could select or extract from images.

I use multiple desktops, each one for a certain purpose and sometimes they have the same wallpaper.

Today I was messing around with different images because I needed to change the wallpaper of one of them so I tried with a couple that I generated with the app and they just fit perfectly to my computer's aspect ratio.

Then it downed on me: Why not port the app to macOS?💡

I had read that Apple made this easier when they released "Mac Catalyst", but I didn't have much time before to test this out, so now that's FHL @ Microsoft, I gave it a try. It's pretty simple, it actually took me ~10分.

So what do you actually need to do?

Go to General -> Deployment Info and select iPad + Mac Catalyst.

If you haven't added LSApplicationCategoryType to your Info.plist, now it's a good time, since it's required for macOS apps.

That's it! 🎉 Now all you have to do is to click on "Add macOS App" in App Store Connect just like when you first added the iOS App.
