You have to learn a whole new Apple-only programming language to do iOS (Swift or Objective-C) in addition to the iOS framework/libraries. Not to mention buying a Mac and paying Apple $100 for a developer account.
Android, on the other hand, was pretty straightforward to get started with for me as someone with Java experience.
Getting started is one thing, completing a product is another. It's not an uncommon metric to apply a 1.5x or 2x multiplier to the development time of an iOS app to obtain the time to develop the Android one.
I would also argue that from the same starting point (no java experience and no Swift experience) the learning curve is way smoother on iOS, with more fine tuned APIs and better tools (interface builder can be picked up easily by a designer with no coding background).
