A JavaScript library for building user interfaces
One of the things I've been most impressed with at Facebook: GraphQL. It's going to change the way APIs are done.
ComponentKit
I'm proud to announce the open sourcing of ComponentKit, the UI library that powers Facebook's News Feed on iOS. Developing it has been a lot of fun.
React-Inspired Views
I wrote an article for objc.io about the React-inspired view framework I've been working on lately.
Second Curtain
If you're not using FBSnapshotTestCase for testing iOS views, you should be.
If you're using it with a continuous integration system, you should use Ash Furrow's Second Curtain. It's a cool tool that automatically uploads failures to S3 so you can download them on your local machine instead of tediously re-running the test. Amazing!
I started using Atom but couldn't find a decent syntax highlighting theme. Here's my attempt to replicate Xcode's default theme.
For the past year or so I've been leading a project to migrate away from Core Data for Facebook's News Feed—read about it here!
We've been doing a lot of work making News Feed faster at Facebook—listen to me talk about it at @Scale 2014.
Sum Types
Sum types are something you learn about, then miss in every language that doesn't have them. I really wish there was an elegant, idiomatic implementation of them in C++.
Dot Notation
Dot notation in Objective-C was a mistake. If there were one language choice I could undo, that would be it.
See me talk about building Facebook for iOS. I worked on this talk with Alan Cannistraro and had a lot of fun delivering it here at the NYC Facebook Mobile Developer Conference.
asm.js
"asm.js does not support applying the multiplication operator to integer operands" "a bitwise OR [with 0] coercion annotates a parameter as having type int"
I have no words.
The feature I miss most in Xcode.
Spot on.
A replacement for NSURLConnectionDownloadDelegate
In my previous post I noted that NSURLConnectionDownloadDelegate would provide a slick way to download files to the filesystem in iOS 5—but it doesn't work unless you're using it in a Newsstand app.
If you're an old hand at Cocoa, you may remember the NSURLDownload class. It did essentially the same thing: filesystem downloads from a URL. But it's never been available on iOS.
Enter AEURLDownload. It's a dead simple class to asynchronously download a URL to the local filesystem. It uses NSURLConnection behind the scenes and saves to a temporary file which is properly created with mkstemp, so it's safe even for use in non-sandboxed apps. When the file finishes downloading, your completion block is called so you can move the file where you want it. If you're looking for NSURLDownload for iOS, AEURLDownload is what you want.
It doesn't have progress callbacks yet, but stay tuned; they're coming soon.
NSURLConnectionDownloadDelegate doesn't work
Surprise undocumented fact: NSURLConnectionDownloadDelegate is only for Newsstand apps. If you attempt to use it in a non-Newsstand app, it will appear to succeed but pass you a nonexistent file path.
More generally, Newsstand is pretty neat but it's silly for Apple to restrict its functionality to news apps. For example, take my subway app: it could definitely benefit from downloading service change data daily if you're plugged in at 4AM (which is what Newsstand allows you to do). But since I'm not a "news" app, I can't do that.
AEURLConnection
I just published AEURLConnection, a simple library for iOS that lets you use iOS 5's slick new sendAsynchronousRequest:queue:completionHandler: API on iOS 4.
It also helps you solve the nasty Deallocation Problem by guaranteeing that your completion block will be released on the main thread. Check it out!
