title: How can I find out the Objective-C generics type?
body: <p>Xcode 7 contains an Objective-C variant, where you can define a type-hint for (homogenous) <code>NSArray</code> return values and properties, defined such as <code>NSArray&lt;UIImage*&gt;</code>.</p>
  
  <p>I'd like to use this feature to rewrite my JSON-deserializer class (which needs such kind of type hints – previously I have solved this by adding a <code>-(Class)jsonHintForKey:(NSString*)key</code> to my classes that have homogenous arrays as properties.)</p>
  
  <p>Do you know whether (and if so, how) I can use the Objective-C runtime to get the class of this new type hint at runtime?</p>
