Convert your existing code to Oxygene, C# or Swift.
Elements comes with a unique feature called "Oxidixer" that lets you convert existing C#, Java and Objective-C code into Oxygene, C# or Swift with a single click. In Fire and Visual Studio, you can convert code on the fly as you paste it from the clipboard (very useful for sample code found online), or you can convert whole files as you add them to your project (for example when migrating a project to Elements).
Oxidizer is not magic, and it cannot handle every corner case, but it gets you a good step of the way there. You can read more about Oxidizer here, or try it below:
