I have to disagree on Android being easier to get into. The standard libraries and tooling (especially emulators and profilers) are dumpster fires compared to Apple's offering. Just some examples: Non-Web Javascript integration is a third party library. HTTP requests are a third party library. Everything that needs native resources in the JVM goes through an interface called JNI that has a 512 entries limit in the reference table, often requiring you to do manual reference cleanup in your hot loops.
I think it really depends on what the op is looking to make. I made the generalization mostly based on the OS and languages (most universities starting from at least 15 years ago taught Java in at least a few classes whereas objective-c and swift are only iOS specific). I haven't had to deal with your specific examples but I suppose in your case iOS might be easier. I still believe overall Android is easier to get into for the "average" person.
IMO, for the average person, doing iOS with Swift will be easier, except, and only for some simple usecases, if that person is already experienced with Java.
