解決XCode運行app在模擬器上，提示模擬器不存在

問題

因爲清理磁盤數據，用XCode運行app在模擬器上，提示模擬器不存在

Unable to boot device because it cannot be located on disk
The device’s data is no longer present at /Users/[user name]/Library/Developer/CoreSimulator/Devices/D651BCC7-29FD-4B91-82F6-E255E856EA2F/data.

解決方法

1. 退出XCode，退出模擬器
2. 打開命令行工具Terminal
3. 運行命令

xcrun simctl erase all
