Don't they offer downloads of Xcode outside of the App Store if you pay their developer program fee? That includes their SDKs. Theoretically there is only an expenditure of time and effort to build an iOS app on Linux. I forget if it is against their terms or not, but I don't think the SDK available is a barrier.

While not strictly required, for me macOS has been less cantankerous for running Android Studio on compared to Windows/Linux too.

How about photography and video production?

Ah, forgot about it. Perhaps a yes, considering lots of photographers and video editors work on Mac.
