I’ve run into the same problem as found in this question. However, I have a follow-up question. I seem to be in the same situation as the original asker: I have a plist with a hierarchy of dictionaries that define a configuration screen. These are not mutable and will stay the same throughout the application. Since the original discussion seems to focus on problems arising from mutating the dictionary, I must ask for comfirmation: is the order of a dictionary guaranteed the same as they are in the plist, i.e. as it is read (with initWithContentsOfFile)? Can I use allKeys on it in this case to get a correct-order array of keys if the dictionary never changes?

    No, the keys are not likely to appear in the same order as your plist file. I can’t look under the hood, but I would guess that the keys are ordered in whatever way that provides an efficient look-up. The documentation for allKeys says that the order of the elements in the array is not defined.
