I'd have to say my biggest problem is just learning the classes and best practices of Cocoa.
Sometimes I wish Xcode could support JAVA IDE style inline API reference pop-ups. Having to flip to the documentation and back again can be quite irritating. Having instant access to a reference can really speed up learning the individual class interfaces and just streamlines the workflow in general. Also, having a firm grasp of design patterns (and how they are modified in Objective-C land) is also a must.
