Running objective-c tests from the command line (with color)
# based on https://gist.github.com/3349345
# Thanks, @alloy!
#
# To get your project ready for this, you'll have to create a scheme for your unit test project, make sure run is checked in
# the build step, and then delete the Test Host setting.
# Also, make sure you have the colored and open4 gems installed.

Meta alert: A Kiwi matcher that allows you to define custom matchers with one block instead of subclassing KWMatcher.
#import "KWMatcher.h"
typedef BOOL (^FTKiwiCustomMatcherBlock)(id subject);
@interface FTKiwiCustomBlockMatcher : KWMatcher
// Your custom matcher block will receive the expectation ‘subject’ and must
// return `YES` if the expaction passes or `NO` if it fails.
- (void)be:(FTKiwiCustomMatcherBlock)block;

A great little helper for handling keyboard animations nicely. Just put this view at the bottom vertically of your views and it will move everything else up and down for you.

/**
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.
