Final Cut Pro has significant limitations over what can be done on the Mac, which limits their ability to do project sharing between the two platforms.

Thats nothing compared to the bash build stages and custom permission setups, third party libraries, bespoke source code management scripts, ruby-based project initialization and preprocessing scripts I've seen amongst Xcode-based projects.

When those fail, you are troubleshooting through logs and at the filesystem level.

If the idea is a version of Xcode without those things but is otherwise fully featured, I think that is actually speaking about some future version of Swift Playgrounds.

Otherwise, "Xcode for iPad" is basically a jailed Mac VM.
