💡second choice is KOTLIN the new language supported by google in Android Studio 3 for developing android apps.
🔥third choice is MS Visual Studio using XAMARIN for the C# programmers.
➡[second :iOS ]
✔Swift

Answer 2

Choose Swift for iOS, yeah. For Android (not games) I'd recommend Java

Answer 3

Java and XML are the best supported languages in my opinion. Note, Java and XNL do different things in the app. So I would recommend understanding both. However start with Java.
