Is there a way to port over a native iOS app to Android (as a temporary makeshift solution)

For a mobile app that is being made natively for both iOS and Android (without the use of React/cross-platform), I have to make a budget choice to develop one or the other first. If I develop the iOS first, is there some way to easily port over the iOS application and make it compatible with android phones (perhaps via some service or framework). Language is Swift or Objective C for the iOS.

I'm aware of using React for cross-platform, however for performance purposes native development suits my needs better.
