Removed properties appear in AppDelegate

Hi,

Help:

Why my removed properties in the script appear again if I control click on AppDelegate Blue Box?
There is a way to purge them?

Hi,

try to clean the project (⇧⌘K)

Hi Stefan,

I try to Clean Project and also quit Xcode and reopen the project many times.
Nothing.

I restarted the Mac and now all is OK (!!!)
I also deleted the DerivedData folder.
