Recursive Core Data saves with RAC. Works with nested contexts!
@implementation NSManagedObjectContext (INAdditions)
- (RACSignal *)in_saveChanges
{
return [[RACSignal startEagerlyWithScheduler:RACScheduler.scheduler block:^(id<RACSubscriber> subscriber) {
__block void (^recursiveBlock)(NSManagedObjectContext *);
recursiveBlock = [^(NSManagedObjectContext *context) {
[context performBlock:^{
NSError *error = nil;
[context save:&error];

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;

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

A real world usage for git subtrees.

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

Sublime Text 2 performance on 13" Retina MBP

I love my new 13" rMBP, but there are performance issues here and there - Sublime is definitely one of them. However with a few tweaks I've been able to get performance up to what I would call acceptable.

Steps:

  1. Grab the latest build of Sublime (currently 2219); it has retina fixes. http://www.sublimetext.com/nightly
  2. Install HEAD of the Soda theme (instructions under "Download Manually"): https://github.com/buymeasoda/soda-theme/
  3. Make these tweaks to your User Preferences (cmd-,):
