 ##Custom Transfoms
 ObjectMapper also supports custom Transforms that convert values during the mapping process. To use a transform, simply create a tuple with the mapper["field_name"] and the transform of choice on the right side of the '<=' operator:
 ```swift
-birthday <= (mapper["birthday"], DateTransform<NSDate, Int>())
+birthday <= (map["birthday"], DateTransform<NSDate, Int>())
 ```
 The above transform will convert the JSON Int value to an NSDate when reading JSON and will convert the NSDate to an Int when converting objects to JSON.
