""" File: reveal.py

Add to ~/.lldbinit:
    command script import ~/.lldb-scripts/reveal.py

Q: Want to automatically load the Reveal lib on launch while debugging from Xcode?
A: In Xcode:
    Add a Symbolic Breakpoint
    Symbol: "UIApplicationMain"
    Action: Debugger Command with value "reveal"

NSUserDefaults is kinda like git

Note that like all analogies, this is not a perfect one. I find it helps me think about it though. Also, don't try to draw conclusions about performance from this analogy :)

-[NSUserDefaults setObject:forKey:] is like...
<edit file to add key and value>
git add file
git commit
dispatch_after(some time, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
    [[NSUserDefaults standardUserDefaults] synchronize]
});
