Thank God that Xcode is not on iPad. It is bad enough that Apple is dumbing down on everything that makes macOS a great OS. Dumbing down a development platform would be a shame.
Let macOS shouls be kept PRO for professionals that need to perform serious tasks. Let IOS/iPadOS be for playing consumers that just need silly apps to do silly things. Merging them would not be sensible. In my personal opinion IOS is not a suitable development platform for any self respecting developer.
You clearly don't know what you are saying.
I'm a developer. And except editing code, my iPad Pro 12.9 does everything my Mac does.
The iPad must have a decent code editor with remote execution. That would be insane. iPadOS is not simply for playing consumer.
