 Problem: System data has huge data.How can i delete the data and recover my spaces in my mac?. I had tried to delete xcode caches and other things but i'm not able to resolve. Solution: clear the the data inside the path that not used with device id you can find from xcode->menu->window->devices and simulator-.>simulator then it will show the identifier. You can check with the below device list and find the unused old one. you can remove the old and unused simulator data in the path to delete /Users/yourMac/Library/ Developer/CoreSimulator/ Devices. Because the xcode keeps the old simulators on the above path but it's not used in the new xcode. So it has huge data with unused.You can remove all and proceed. Then the system data will be low after doing this work.
