/**
 Provides the ability to verify key paths at compile time.
 
 If "keyPath" does not exist, a compile-time error will be generated.
 
 Example:
    // Verifies "isFinished" exists on "operation".
    NSString *key = SQKeyPath(operation, isFinished);
 
    // Verifies "isFinished" exists on self.

Using HockeySDK as an example

1. Download HockeySDK 3.0.0

2. Run this command:

    echo "int main(int argc, char *argv[]) { return 0; }" | clang -x c -arch armv7 -ObjC -isysroot `xcode-select -print-path`/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -Xlinker -objc_abi_version -Xlinker 2 -F$HOME/Downloads/HockeySDK-iOS-3/HockeySDK.embeddedframework -framework HockeySDK -framework Foundation -framework UIKit -framework QuartzCore -framework CoreGraphics -framework CoreText -o $TMPDIR/HockeySDK - && class-dump $TMPDIR/HockeySDK
   

Adapt all the -framework options according to the documentation that comes with the iOS static framework.
