I'm totally biased towards Android development using Gradle and kotlin.

Gradle can be a pain, but if I look at what our neighbors at the iOS team experience (constantly having to manually merge project files, not being able to simply import some libraries, ...) it's hardly a nightmare.

Specifically adding dependencies is super easy? Just specify which repo they're in (mavenCentral or Google or whatever) and add dependencies under "dependencies". When running or syncing, Gradle does the rest.

Yes, exactly. SwifDroid automatically wires all the necessary Gradle dependencies, so you don’t have to manage them manually.
