筆記：清除 Xcode 所佔用硬碟空間

~/Library/Developer/XCTestDevices


~/Library/Developer/CoreSimulator/Devices
存放所有曾經開過的模擬器（各種版本的模擬器），都會在這裡開一個專用的 Folder 存放
可以全部刪除

目錄裡頭像這樣：

$ ls -1 ~/Library/Developer/CoreSimulator/Devices
002FF2F2-AF6F-46CE-8A5D-EB7200401118
00493DA7-441C-459F-8AB1-71483F27EEC5
01095431-499E-4AED-A6F2-183A751DED06
061C60FC-6719-4349-9604-51D0D8237934

066F7D71-9B95-4ECA-BD54-2585FC3AF028
device_set.plist

這個目錄下，我居然有  336 子目錄，全部刪掉後，還原 30+GB 空間

刪除的步驟：
1.關閉 Xcode 以及所有模擬器
2.兩個命令

rm -rf ~/Library/Developer/CoreSimulator/Devices

killall -9 com.apple.CoreSimulator.CoreSimulatorService   
注意，要執行這個命令
不然 Xcode 無法啟動新的模擬器

device_set.plist 是個 xml 檔案
長得像這樣：

~/Library/Developer/Xcode/DerivedData
這裡存放所有 build 過的 app 的檔案
當寫越多 app 或常常下載別人的 source code 測試
會在這個目錄佔用大量空間
隨時刪除 無所謂..


/Applications/Xcode.app/Contents/Developer/Platforms
各平台的 SDK 目錄，用不到的就刪除
例如 AppleTVOS.platform  (佔了2GB)
 

$ ls -1 /Applications/Xcode.app/Contents/Developer/Platforms
AppleTVOS.platform
AppleTVSimulator.platform
MacOSX.platform
WatchOS.platform
WatchSimulator.platform
iPhoneOS.platform
iPhoneSimulator.platform

/Library/Developer/CoreSimulator/Profiles/Runtimes
Simulator runtime
一個版本 約佔 4~5GB

$ ls -1 /Library/Developer/CoreSimulator/Profiles/Runtimes
iOS 10.0.simruntime
iOS 10.3.simruntime
iOS 12.2.simruntime
iOS 13.1.simruntime

~/Library/Developer/Xcode/iOS DeviceSupport
Mac 電腦連接過的 iOS 設備( iPhone/iPad...)，就會在這裡產生一個 folder ，
一個 folder 可能占用多達 2+GB
可以隨時刪除

$ ls -l ~Library/Developer/Xcode/iOS\ DeviceSupport
total 0
drwxr-xr-x  5 fire  staff  160  1 12 16:02 14.2 (18B92) arm64e
drwxr-xr-x  5 fire  staff  160  1 12 16:45 14.3 (18C66) arm64e
drwxr-xr-x  5 fire  staff  160  1 28 14:37 14.4 (18D52) arm64e
**佔用 12GB
