If you stick with being platform-specific, the main way to write apps for iOS is Objective-C, though you can also use Objective C++. On Android, you can write applications in a JVM language like Java, but you can also alternatives like Scala or Clojure if that floats your boat.
Hi There,
What are the programming languages or coding should one learn before developing your own Apps?
Thanks in Advance,
Cheers...
