I'm struck with the same error. But again, I saw posts where they were suggesting to go with Xcode 10.3. I tried that, but again I literally started iOS app development yesterday, and I couldn't tell it wont work for sure.

Sarthak,

Do this as said here: https://github.com/kivy/kivy-ios/issues/434

My conf: Python 3.7.2, OSX Mojave, Cython 0.29.10.... You can try on Catalina.
