case .Authorized: //access contacts
case .Denied, .NotDetermined: //request permission
default: break
}

switch ([CNContactStore authorizationStatusForEntityType:CNEntityType.Contacts]){
case CNAuthorizationStatus.Authorized:
    //access contacts
    break;
case CNAuthorizationStatus.Denied:
    //request permission

    //request permission
    break;
}

Requesting Permission

contactStore.requestAccessForEntityType(CKEntityType.Contacts, completionHandler: { (ok, _) -> Void in
    if access{
        //access contacts
    }
}
