Failed to load Addressbook class CNContactNameFormatter in log

I'm seeing the above error logged against my app in the system log each time it runs. However I don't use that class or even load the address book framework. So what does it mean and how do I get rid of it?

I upgraded to El Capitan this morning, and I now get this error every time I run an app which includes MapKit. I've created a new project, added the Maps capability to the app, then dragged a Map control onto a View Controller and I then get the error when I compile and run. That's with just a half-dozen settings in IB ... there's zero manually-entered application code.


This worked fine yesterday, when I already had the production XCode 7.0.1. installed. So it seems to be a side-effect of El Capitan ...

I am getting this same error - it seems harmless but I can't be sure about anything with Xcode.

same here. After upgrading to El Capitan I get this error

This will go away if you add the ContactsUI.framework

That fixed it! Thanks!

Yeah, of course that will fix it, but what does my project need the ContactsUI.framework for???
