Hint: iPhone / iPad plist properties

If you are trying to add additional properties to the info.plist of a project, but the automatic plist type seems to be wrong, the fix for it is a simple trick.

ctrl-click the plist type to open as plain text file, then to text property list, and then from the menu select View > Property List Type > iPhone Info.plist.

If the values are not selectable, just repeat the process. It seems like a strange bug in Xcode.
