Objective-C is fine, and Swift even more so. If you don't know the platform sure, it is difficult, but that applies to any platform. When you learn native, all those web-tech monstrosities have zero appeal.
iOS development will always be native for me, the tools are not perfect, but they feel right, I can get stuff done in no time. Android on the other hand... I can't express how much I loathe the tools and language. So much that I stopped caring. React native might be an alternative.
