TOOLS

DevCleaner - Clear up some of that space on your mac

If you want to reclaim tens of gigabytes of your storage used for various Xcode caches - this tool is for you! Xcode could store a truckload of stuff in ~/Library/Developer folder. Most of those cached files & symbols are not reclaimed over time and could consume a large amount of your storage, which is especially important if you have relatively small SSD drive.

I ran it on my machine and it cleared up over 30gb! (I had to reboot my machine after running it). As with any tool that goes and deletes a bunch of stuff please use at your own discretion.

In Xamarin, if you observe / subscribe to a particularly-named NSNotification in an object that is IDisposable (this includes any class descended from NSObject!), you MUST explicitly unsubscribe from it in your Dispose handler, or you will get a segfault. And you don't want SegFaults!
