iOS not liking specialFolderPath("Preferences")

When an application is installed on a phone (or in the simulator) a number of initial folders are
created for use by the application. You can locate the paths to these folders using the
specialFolderPath() function with the following selectors:

• home – the (unique) folder containing the application bundle and its associated data and
folders

• documents – the folder in which the application should store any document data (this folder
is backed up by iTunes on sync)

• cache – the folder in which the application should store any transient data that needs to be
preserved between launches (this folder is not backed up by iTunes on sync)

• library – the folder in which the application can store data of various types. In particular,
data private to the application should be stored in a folder named with the app's bundle
identifier inside library. (this folder is backed up by iTunes on sync).

• temporary – the folder in which the application should store any temporary data that is not
needed between launches (this folder is not backed up by iTunes on sync)

• engine – the folder containing the built standalone engine (i.e. the bundle). This is useful for
constructing paths to resources that have been copied into the bundle at build time.
In general you should only create files within the documents, cache, and temporary folders. Indeed,
be careful not to change or add any files within the application bundle. The application bundle is
digitally signed when it is built, and any changes to it after this point will invalidate the signature
and prevent it from launching.
