Clean install on 10.11.1. I create new code signing request and new certificates. When I press build and run, Xcode request acess to keychain I click allow. Nothing hapens in UI.
Sytem log :
SecurityAgent[1889]: Ignoring user action since the dialog has received events from an untrusted source
So apperantly Xcode its not trusted, downloaed form Mac AppStore. I think this is keychain bug.
