Mac-Os 10.14.1: Fehler beim Abrufen des Werts für den Schlüssel 'initializationClass' der Erweiterung 'Xcode.DVTKitDFRSupport.Initializer'

Ich habe MacBook Pro auf Version 10.14.1 (Mojave) aktualisiert.

Seit diesem Moment habe ich folgende Fehlermeldung, wenn ich das Terminal öffne:

2018-11-12 09:03:31.057 xcodebuild[8249:72140] [MT] DVTPlugInLoading: Failed to load code for plug-in com.apple.dt.IDE.DVTKitDFRSupport (/Applications/Xcode.app/Contents/PlugIns/DVTKitDFRSupport.ideplugin), error = Error Domain=NSCocoaErrorDomain Code=3588 "dlopen(/Applications/Xcode.app/Contents/PlugIns/DVTKitDFRSupport.ideplugin/Contents/MacOS/DVTKitDFRSupport, 265): Symbol not found: _OBJC_IVAR_$_NSTextViewIvars.sharedData Referenced from: /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit Expected in: /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit in /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit" UserInfo=, dyldError = dlopen(/Applications/Xcode.app/Contents/PlugIns/DVTKitDFRSupport.ideplugin/Contents/MacOS/DVTKitDFRSupport, 0): Symbol not found: _OBJC_IVAR_$_NSTextViewIvars.sharedData Referenced from: /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit Expected in: /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit in /Applications/Xcode.app/Contents/Developer/usr/bin/../../../SharedFrameworks/DVTKit.framework/Versions/A/DVTKit 2018-11-12 09:03:31.057 xcodebuild[8249:72140] [MT] DVTPlugInExtensionFaulting: Failed to fire fault for extension Xcode.DVTKitDFRSupport.Initializer: Error Domain=DVTPlugInErrorDomain Code=2 "Loading a plug-in failed."

Ich habe noch keine Lösung gefunden. Wie kann ich das lösen?
