Is there a specific Xcode compiler flag that gets set when compiling for iPad?
I want to conditionally compile iPad vs iPhone/iPod Touch code for example:
#ifdef TARGET_IPAD
code for iPad
#else
code for iPhone
#endif
I know there is already TARGET_OS_IPHONE and TARGET_CPU_ARM in TargetConditionals.h but anything that easily and specifically targets iPad?

You can then add swift compiler flags so that we can check the current configuration through code. To do that, goto Project (not target)→Build settings → Swift Compiler → Custom flags → Other swift flags section and edit the different configuration flags. Add the flags using the syntax “ -D <flag_name>”.
Compiler flags are options you give to gcc when it compiles a file or set of files. You may provide these directly on the command line, or your development tools may generate them when they invoke gcc. This section describes just the flags that are specific to Objective-C.
The powerful open-source LLVM compiler for C, C++, and Objective-C is built into Xcode and available from Terminal. With it, your code compiles quickly, and is optimized by Apple to produce blazing-fast apps specifically tuned for the CPUs in iPhone, iPad, and Mac.
The correct API to use for run-time checking of iPad vs. iPhone/iPad Touch is:
BOOL deviceIsPad = ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad);
The UIDevice header filer also includes a convenient macro, UI_USER_INTERFACE_IDIOM(), which will be helpful if your deployment target is < iPhone 3.2.
#define UI_USER_INTERFACE_IDIOM() ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] ? [[UIDevice currentDevice] userInterfaceIdiom] : UIUserInterfaceIdiomPhone)
So you could just say, negatively:
BOOL deviceIsPad = (UI_USER_INTERFACE_IDIOM() != UIUserInterfaceIdiomPhone);
