You don't have many choices for cross-platform tools. You can either use C++ that is quite hard for a lot of people but I would say most popular and most stable. You can use C# or Java with Xamarin but it is very expensive, unstable and it is kind vendor lock-in. You can also use JavaScript but you will lose a lot of performance that is very important on mobile. There are other options like using Lua, RubyMotion but they suffer same problems as JavaScript Bottom line: There isn't convenient, modern, fast, open-source method for cross-platform development. Swift bridges nicely with C and it is built on LLVM so you will be able to use it on Android with Android NDK and bridge it through JNI and Microsoft recently also adopted LLVM so you will be also able to use it there.

  It is far from perfect, maybe one day. Currently it still suffers a lot of problems. Try to write a big application in it and you will soon discover it.

You can use Go with gomobile https://github.com/golang/go/wiki/Mobile#sdk-applications-and-generating-bindings https://github.com/golang/go/wiki/Mobile#sdk-applications-an... . It works okay but the lack of support for exporting slices really limits things.

The performance difference vs. native code is undiscernible. Unfortunately, JavaScript is an awful language to use, so there are tradeoffs. Maybe Titanium + TypeScript would be the sweet spot.

  It depends what you do but once you have a complex application you will see problems with JavaScript.

  I've had the complete opposite experience with Titanium, to the point where it was completely unusable.

    I found some things about it to be frustrating and buggy, but it was still less work than writing two different apps. My code was about 90% shared between devices.

How does RubyMotion suffer the same (performance) problems as JavaScript? Doesn't it compile to C# bytecode?
- jsmith0295 11y ago
  It actually uses the MacRuby stuff to compile to native. But the compiler can't optimize nearly as well as it can for statically typed languages, so there's a pretty significant performance hit on the ruby code itself, though once you've called a native library there won't be any difference.

There is ActionScript 3 even if you think that "flash is dead" in the browser, for mobile and Desktop you can use Adobe AIR for server-side, command-line and shell scripts you use Redtamarin https://github.com/Corsaair/redtamarin https://github.com/Corsaair/redtamarin I'm the dev behind redtamarin but I welcome other projects like perfect. Even if the tech and language are different, different pros and cons, a lot of ideas and features are shared.
