Here is how I understand to develop iOS apps partially in Ada:
0) Install Xcode on Mac.
1) Install Apple's Command-Line Tools from http://developer.apple.com/downloads 
2) Install Homebrew
3) Install Homebrew's gcc49.rb on Mac.
4) Cross-compile nonGUI Ada source code to Cortex-A9 (Apple A5), ARMv7 (Apple A6), ARMv8a (Apple A7).
5) Cross-compile glue(-to-Ada) source code and GUI source code in Xcode/LLVM Objective-C or Objective-C++ to same ARM instruction-set.
6) Link the Objective-C[++] and Ada object files together to produce executable for iOS.  Should this step use Xcode's LLVM linker or GCC's linker?
7) Debug GUI & glue in Xcode's debugger for most recent Objective-C[++] features.  Debug Ada source code in GNAT's debugger for Ada symbol support.

The keyword here truly is homebrew.  Does anyone have any better technique?  Does anyone know of a better-supported Ada development environment for cross-compiling to iOS?
