//  This checker finds issues with Objective-C properties.
//  Currently finds only one kind of issue:
//  - Find synthesized properties with copy attribute of mutable NS collection
//    types. Calling -copy on such collections produces an immutable copy,
//    which contradicts the type of the property.
