I think it's unknown whether Swift Playgrounds on an iPad compiles Swift all the way to arm64 machine code, or is just an interpreter of Swift compiled LLVM intermediate language tokens. If the latter, then you will probably eventually need to export your Swift code from Playgrounds to Apple's new Xcode cloud continuous integration service, before importing your Apple compiled app back to your iPad for standalone local use.Does anyone know if playground 4 will support exporting your code as a standalone app for local use?
