Xcode 12.5 minimum requirements12/5/2023 Aside from the cost and backup complications there is an environmental impact of being wasteful. Efficient use of storage seems to be a weak area for the osx ecosystem but also the community. While I agree in general that living near the edge of a full hd is not a good idea, I'm disappointed in the common community response which is just to get a bigger disc whatever the circumstances. It is quite unreasonable to have 70GB wasted. You can safely delete this directory (i.e. HD/Users/me/Library/Application Support/iPhone Simulator -> 1.8gb They are also used when debugging on devices, but Xcode will automatically regenerate them when you attach a device that doesn't already have a corresponding iOS DeviceSupport directory. Worst case, you can back them up to DVD somewhere and delete them to save space. Use your judgement as to whether you can delete those directories. The directories in "iOS DeviceSupport" are required for symbolicating crash logs from devices running the corresponding version. HD/Users/me/Library/Developer/Xcode/iOS DeviceSupport -> 46.7gb - devices all the way back to 5.0.1 If you change your mind later, you can always create new Simulator devices Make sure you use Xcode (or xcrun simctl) to do the deletion don't just delete them from the filesystem. You can reduce the size of this directory by going to the Devices window in Xcode and deleting any Simulator devices that you don't use (each directory there corresponds to a Simulator device displayed in the devices window). HD/Users/me/Library/Developer/CoreSimulator -> 8.1gb Really, do we need 4, or 5 folders of simulators, amassing almost 70gb of disk space?Īnd then reinstall Xcode from scratch? will this actually give some space back? HD/Users/me/Library/Application Support/ iPhone Simulator -> 1.8gb HD/Users/me/Library/Developer/Xcode/ iOS DeviceSupport -> 46.7gb - devices all the way back to 5.0.1 HD/Users/me/Library/Developer/ CoreSimulator -> 8.1gb HD/Users/me/Library/Developer/Shared -> 8.7gb HD/Users/me/Library/Developer/Xcode -> 53gb HD/Users/me/Library/Developer -> 69.9gb - why? HD/Library/Developer/ CoreSimulator -> 13gb It's been backed up and updated regularly, and I wonder if this has left me with a lot of old cruft. This mac has a primary drive that started as Snow Leopard on a white macbook back in 2009. So perhaps it's time to wipe Xcode and reinstall clean. I tried installing the Xcode 7.1 beta on a separate drive however it insists on installing all of the simulators on the primary hard drive, and it runs out of space. I'm running a Mac that generally has about 12 GB spare. I've been trying to install Xcode 7 tonight with no real luck.
