Can I save files/folders in NSSearchPathDirectory.ApplicationDirectory? NSSearchPathDirectory.DocumentDirectory is not ideal for me

iOS 8.4 | Swift 2.1

When I was tried to create a new folder in NSSearchPathDirectory.ApplicationDirectory, I followed with this error on device (in simulator it did worked, though):

code:

let docuPath:NSURL = NSURL(fileURLWithPath: NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.ApplicationDirectory, NSSearchPathDomainMask.UserDomainMask, true)[0])
ConstantsVO.imagePath = docuPath.URLByAppendingPathComponent("imagegallery")
if !NSFileManager.defaultManager().fileExistsAtPath(ConstantsVO.imagePath.path!)
{
     do
     {
          try NSFileManager.defaultManager().createDirectoryAtPath(ConstantsVO.imagePath.path!, withIntermediateDirectories: true, attributes: nil)
     }
     catch let error as NSError
     {
          NSLog("\(error.localizedDescription)")
     }
     catch
     {
          print("general error - \(error)", terminator: "\n")
     }
 }

error

However, using NSSearchPathDirectory.DocumentDirectory did worked for me and worked expectedly. But in my application, I've feature to share/import through iTunes, so I have the "Application supports iTunes file sharing" TRUE in my info.plist - this exposed NSSearchPathDirectory.DocumentDirectory in iTunes. I don't want the files/folders that I'm saving through my app to be expose to the user in iTunes. Then where should I save the files/folders yet can able to use file sharing through iTunes by exposing NSSearchPathDirectory.DocumentDirectory?

I found the answer from this post is helpful: Path directory usable in iOS

As far as I know only these are usable on iOS:

NSDocumentDirectory is Documents/ (persistent, backed up, may be visible in iTunes) NSLibraryDirectory is Library/
(persistent, backed up, not visibe to the user) NSCachesDirectory is Library/Caches/ (not backed up, may be cleared by system)

Now after I'm using NSSearchPathDirectory.LibraryDirectory the I'm having no NSFileManager error on device nor the directories/files I'm storing inside NSSearchPathDirectory.LibraryDirectory are exposed to the users in iTunes sharing tab.

Great!
