For a complete removal of Xcode 10 delete the following     Applications Xcode app    Library Caches com apple dt Xcode   Library Developer    Library MobileDevice   Library Preferences com apple dt Xcode plist  Library Preferences com apple dt Xcode plist  System Library Receipts com apple pkg XcodeExtensionSupport bom  System Library Receipts com apple pkg XcodeExtensionSupport plist  System Library Receipts com apple pkg XcodeSystemResources bom  System Library Receipts com apple pkg XcodeSystemResources plist  private var db receipts com apple pkg Xcode bom   But instead of 11  open up  private var in the Finder and search for  Xcode  to see all the  dna  left behind    and selectively clean that out too  I would post the pathnames but they will include randomized folder names which will not be the same from my Mac to yours   but if you don t want to lose all of your customizations  consider saving these files or folders before deleting anything      Library Developer Xcode UserData CodeSnippets   Library Developer Xcode UserData FontAndColorThemes   Library Developer Xcode UserData KeyBindings   Library Developer Xcode Templates   Library Preferences com apple dt Xcode plist   Library MobileDevice Provisioning Profiles

FOR UNINSTALLING AND THEN BEING ABLE TO REINSTALL XCODE 9 CORRECTLY  I followed the topmost answer for deleting Xcode 7 and found a major error  deleting   Library Developer will delete an important folder called PrivateFrameworks  which will actually crash Xcode everytime you reinstall and force you to have to get your friends to send you the PrivateFrameworks folder again  a complete waste of time seeing if you needed to uninstall and reinstall Xcode urgently for immediate work purposes   I have tried editing the topmost answer but see no changes so below is the modified steps you should take for Xcode 9   Delete   Applications Xcode app    Library Preferences com apple dt    Generally anything with com apple dt  as prefix is removable in the Preferences folder     Library Caches com apple dt Xcode    Library Application Support Xcode  Everything in   Library Developer directory except for   Library Developer PrivateFrameworks

This answer should be more of a comment against Dawn Song s comment earlier  but since I don t have enough reputation  I m going to write it as an answer   According to the forum page  https   forums developer apple com thread 11313   In general  you should never just delete the CoreSimulator Devices directory yourself   If you really absolutely must  you need to make sure that the service is not runnign while you do that   eg      Quit Xcode app  Simulator app  etc sudo killall -9 com apple CoreSimulator CoreSimulatorService rm -rf   Library   CoreSimulator   I definitely ran into this issue after deleting and reinstalling Xcode   You might encounter a problem trying to connect the build to a simulator device   The thread also answers what to do in that case   gem install snapshot fastlane snapshot reset simulators
