We actually _do_ pattern match UIColor colorWith and turn it into an initializer. If there are two initializers after we pattern match (e.g., UIColor colorWith and initWith), we eliminate the duplicate.
1. Return type is `instancetype` or `MyClassName *`
2. Method takes at least one argument
3. Method name starts with a "class suffix"; that is, a suffix of the class name, with the restriction that you can't have partial words. The first letter may optionally be lower case.
The class suffix (optionally followed by "With" like in the `initWith` conversion) is stripped off and the rest of the method name is used for the first parameter, with the first letter lower-cased.
For example, the following conversions apply:
+[MyClassName myClassNameWithObject:obj] -> MyClassName(object: obj)
+[MyClassName classNameWithObject:obj] -> MyClassName(object: obj)
+[MyClassName nameObject:obj] -> MyClassName(object: obj);
