If you happen to be an iOS developer  Check how many simulators that you have downloaded as they take up a lot of space  Go to     Library Developer Xcode iOS DeviceSupport Also delete old archived apps  Go to     Library Developer Xcode Archives I cleared 100GB doing this

That directory is part of your user data and you can delete any user data without affecting Xcode seriously  You can delete the whole CoreSimulator  directory  Xcode will recreate fresh instances there for you when you do your next simulator run  If you can afford losing any previous simulator data of your apps this is the easy way to get space   Update   A related useful app is  DevCleaner for Xcode  https   apps apple com app devcleaner-for-xcode id1388020431

for Xcode 8   What I do is run sudo du -khd 1 in the Terminal to see my file system s storage amounts for each folder in simple text  then drill up down into where the huge GB are hiding using the cd command   Ultimately you ll find the Users  Library Developer CoreSimulator Devices folder where you can have little concern about deleting all those  devices  using iOS versions you no longer need   It s also safe to just delete them all  but keep in mind you ll lose data that s written to the device like sqlite files you may want to use as a backup version   I once saved over 50GB doing this since I did so much testing on older iOS versions
