NSEnumerator and the missing peek method

Hello,

I'm currently busy with a project where I regularly make use of a NSEnumerator object to iterate over a set of objects. The "problem" I'm experiencing is that there is no method to peek at the next object (for example [enumerator hasNext]). I circumvent the need to peek via the enumerator with counting the objects of the enumerator ([[enumerator allObjects] count]) and check when the last element is reached (and do something).

The questions :
- Why didn't the AppKit developers include this (the hasNext method) in the first place?
- How do other developers conquer this problem?

With kind regards,
Jan Vereecken
