Xcode - free to clear devices folder?

Question

I am deleting some folders and files to make more space on my drive. I know that in path:

~/Library/Developer/CoreSimulator/Devices/

There are

Answer 1

in Xcode 8:

1) Run $ sudo du -khd 1 in Terminal to see the folder size of each folder;

2) Run $ cd library/developer/coresimulator/devices to see the GB stored for all your Xcode simulators;

3) You'll begin to see where a ton of storage is hiding! Now just navigate to that location on your Macintosh HD and view the devices.plist in each device folder;

4) Decide which folders to delete and keep by deleting any simulators/iOS versions you've ran in the past but no longer need for testing. Old sqlite versions that could act as old backups, or other content exists in these folders, so consider that before you delete everything in this folder.

I saved over 50GB the first time I did this.
