It looks like iPad users will soon be able to publish their apps to the App Store with Swift Playgrounds 4, without having to build them on a Mac first.
Create an app with an iPad and Swift Playgrounds 4
Swift Playgrounds has given iPad users the ability to play around with coding and app/game design for a while now, but actually publishing their work hasn’t been so straightforward. According to 9to5Mac, that’s all set to change with the release of Swift Playgrounds 4 (the 4.0 release), which will allow iPad users to submit directly to App Store Connect.
This should make submitting apps a lot smoother for iPad users, who previously had to build their apps on a Mac using Xcode before publishing.
According to the screenshots obtained by 9to5Mac, it appears that users will be able to create an icon for their app using templates built into version 4.0. There is also an option to create a custom icon using a separate image file.
