How to Completely Uninstall Xcode and Clear All Settings

I have an issue that I can only assume is with Xcode, where my apps take forever to run and crash the phone/restart about 75% of the time. I tried using older versions of the code that I'd saved instead, but they had the same effect, which they didn't use to have about a month ago.

I've looked up every single possible way to solve this issue for the past few weeks have haven't found anything, so I want to completely uninstall Xcode and clear all settings; but I can't find a way to do this. I can uninstall it, but when I reinstall it, it still has all of my old settings and lists of projects etc. How can I completely uninstall it?

Solution 1:

For complete removal old Xcode 7 you should remove

1. /Applications/Xcode.app
2. /Library/Preferences/com.apple.dt.Xcode.plist
3. ~/Library/Preferences/com.apple.dt.Xcode.plist
4. ~/Library/Caches/com.apple.dt.Xcode
5. ~/Library/Application Support/Xcode
6. ~/Library/Developer/Xcode
7. ~/Library/Developer/CoreSimulator

Solution 2:

For a complete removal of Xcode 10 delete the following:

1. /Applications/Xcode.app
2. ~/Library/Caches/com.apple.dt.Xcode
3. ~/Library/Developer
4. ~/Library/MobileDevice
5. ~/Library/Preferences/com.apple.dt.Xcode.plist
6. /Library/Preferences/com.apple.dt.Xcode.plist
7. /System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.bom
8. /System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.plist
9. /System/Library/Receipts/com.apple.pkg.XcodeSystemResources.bom
10. /System/Library/Receipts/com.apple.pkg.XcodeSystemResources.plist
11. /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:

1. ~/Library/Developer/Xcode/UserData/CodeSnippets
2. ~/Library/Developer/Xcode/UserData/FontAndColorThemes
3. ~/Library/Developer/Xcode/UserData/KeyBindings
4. ~/Library/Developer/Xcode/Templates
5. ~/Library/Preferences/com.apple.dt.Xcode.plist
6. ~/Library/MobileDevice/Provisioning Profiles

Solution 3:

1. Open Storage Management

   • Go to  > About This Mac > Window > Storage Management
   • Or, hit ⌘ + Space to open Spotlight and search for Storage Management.

2. Select Applications on left pane.

3. Right click on Xcode on the right pane and select delete.

This will remove XCode from the installed applications list of your Mac's App Store.

Update: This worked for me on macOS Sierra 10.12.1.

Solution 4:

Before taking such drastic measures, quit Xcode and follow all the instructions here for cleaning out the caches:

How to Empty Caches and Clean All Targets Xcode 4

If that doesn't help, and you decide you really need a clean installation of Xcode, then, in addition to all of the stuff in that answer, trash the Xcode app itself, plus trash your ~/Library/Developer folder and your ~/Library/Preferences/com.apple.dt.Xcode.plist file. I think that should just about do it.

Solution 5:

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
