Run Loop Source
View Readme.markdown

CFRunLoopSource is cool. It lets you build behavior similar to the mechanisms that drive setNeedsLayout and setNeedsDisplay in UIKit.

I found myself in need of something like this a couple of times. It's great to know that no matter how many times I say I need to update something, I will get a single callback at the end of the run loop that gives me a chance to perform my work.

Here is a little Swift wrapper that makes the API easier to deal with.

The URL contains a plist, and inside that is coded another plist. Together, they make references to Apple IP addresses, ports, web services, Netflix, and Apple TV. What is this?

Edit: It looks like AVPlayer encounters an eror in the simulator that points to this URL as seen here: Thanks to @mwhuss for sharing this with me.

Outer property list:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "">
