How different are Android and iOS app development?

It’s perfectly possible to be both an iOS and an Android app developer .

While Android apps are built mainly with Java and with Kotlin, iOS apps are built with Swift . The main difference between the two programming languages is that iOS app development with Swift requires writing less code and therefore, iOS apps coding projects complete faster than apps made for Android phones.

Xamarin is a cross-platform technology that makes it possible to build native applications for Android and iOS using a single, shared codebase . Like other technologies such as React Native and NativeScript, it allows development teams to spend less time writing code for both platforms.
