I wanna develop IOS and android apps. Which code lenguage should i learn?

Answer 1

Go for Java/Lua (Just go for Java though), you may want to learn Swift too. C#/F# is also a decent idea but optional , as there will only ease your job in making small android apps, but you will still need java/lua for larger apps.

Answer 2

the android apps are developed with Java language, and IOS apps are developed with Swift language.

Answer 3

swift or objective C
