MacBook Air and Xcode: Free up Disk Space by Removing Unwanted/Unavailable Device Simulators Tips, Tricks and Tutorials 29 OCT 2017

iOS software development on a MacBook Air inevitably then means that you have a couple of Xcode versions installed on your device, and as we all know, these chew up a fair bit of disk space in the process. One way to free up some disk space is to remove some of the unwanted or perhaps unavailable device simulators that build up with each Xcode update.

The first step is of course to see what you do in fact have installed, and the easiest is to do this is to make use of the simctl tool that comes with Xcode 6+. To do this, launch a terminal and run:

xcrun simctl list devices

Note the use of xcrun to locate and execute the latest development tools. In a user friendly twist, simctl allows you to bulk delete all unavailable simulators with:

xcrun simctl delete unavailable

You can also target specific devices for deletion by simply specifying them either by name or ID:

xcrun simctl delete D26C18BC-268C-6F0B-9CD8-8EFFDE6619E3

This process can actually free up quite a bit of space, particularly if you’ve been through a number of Xcode updates in the past.
