Xcode再インストール手順

Screen動画撮りたくてXcode 12.5にバージョンを上げたらFlutterアプリが起動しなくなったため、削除してダウングレードした。

Xcodeを全削除 する

sudo rm -rf /Applications/Xcode.app
sudo rm -rf /Library/Preferences/com.apple.dt.Xcode.plist
sudo rm -rf ~/Library/Preferences/com.apple.dt.Xcode.plist
sudo rm -rf ~/Library/Caches/com.apple.dt.Xcode
sudo rm -rf ~/Library/Application Support/Xcode
sudo rm -rf ~/Library/Developer/Xcode
sudo rm -rf ~/Library/Developer/CoreSimulator

More Downloads for Apple DevelopersからXcode12.4を落とす

https://developer.apple.com/download/more/?=xcode
https://download.developer.apple.com/Developer_Tools/Xcode_12.4/Xcode_12.4.xip
解凍して Application ディレクトリにつっこむ
terminalで

xcrun simctl erase all
