How to get “Library” path on actual iOS device

问题

I am using the following code to my app base directory:

// /private/var/mobile/Applications/exampleID/example.app/ 
FAppDataDirPath := GetHomePath + PathDelim + Application.Title + '.app' + PathDelim;
// /private/var/mobile/Applications/exampleID/example.app/Library/
FAppDataLibraryDirPath := FAppDataDirPath + 'Library' + PathDelim;

On iOS simulator both these paths exist.

However, on the iOS device only FAppDataDirPath exists. The "Library" variation can not be created using e.g ForceDirectories

What is wrong? :(
