How to uninstall downloaded Xcode simulator? [duplicate]

Question

You can remove them from /Library/Developer/CoreSimulator/Profiles/Runtimes (Not ~/Library!):

NOTE: This will only remove a device configuration from the Xcode devices list. To remove the simulator files from your hard drive see the previous answer.

For Xcode 7 just use Window \ Devices menu in Xcode:

Then select emulator to delete in the list on the left side and right click on it. Here is Delete option:

That's all.

Run this command in terminal to remove simulators that can't be accessed from the current version of Xcode in use.

xcrun simctl delete unavailable

Also if you're looking to reclaim simulator related space Michael Tsai found that deleting sim logs saved him 30 GB.

~/Library/Logs/CoreSimulator

Slightly off topic but could be very useful as it could be the basis for other tasks you might want to do with simulators.

I like to keep my simulator list to a minimum, and since there is no multi-select in the "Devices and Simulators" it is a pain to delete them all.

So I boot all the sims that I want to use then, remove all the simulators that I don't have booted.

Delete all the shutdown simulators:

xcrun simctl list | grep -w "Shutdown"  | grep -o "([-A-Z0-9]*)" | sed 's/[\(\)]//g' | xargs -I uuid xcrun simctl delete  uuid

If you need individual simulators back, just add them back to the list in "Devices and Simulators" with the plus button.
