It seems that at least some of the CNContacts_PredicateExtensions are just factory methods:
let predicate: NSPredicate = CNContact.predicateForContactsMatchingName("O'Brien")
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactRelationsKey]
let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(predicate, keysToFetch: keysToFetch)
while we have them as extension methods:
var namePredicate = (new CNContact()).GetPredicateForContacts ("O'Brien");
It sounds like all static selectors in categories should be handled this way.
We'll discuss this in a future team call
Manually fixed in maccore/xcode7 99a500b215916890f53f51230b89428a1b50fc1e
The generator will be updated to issue warnings in such cases, so it will be easier to spot those ugly API.
