How a single codebase can be

your pass to a multi-platform world of

revenue

What is Marmalade Juice?


Marmalade Juice will allow developers to take native

iOS projects using typical iOS frameworks, and

migrate them quickly and easily to Android and other

platforms.

What is Marmalade Juice?


A porting “ecosystem” for taking iOS apps to Marmalade

A “middleware” layer on top of the Marmalade SDK

A set of tools and libraries

Why use Marmalade Juice?


Recompile Obj C rather than rewriteNative codeIntegration with Xcode IDEIntegration with Marmalade simulatorPotential for multiple target platforms from single codebase

Focus effort on optimising & polishing for target platform, not on the labour of porting

What Marmalade Juice consists of?


Common iOS Framework libraries

Clang compiler toolchain

Static compatibility analysis tool

iOS Xcode project converter

gprof for on-device profiling

Supporting Marmalade SDK extensions

How do you use Marmalade Juice?
