NSFileManager delete contents of directory

Question

How do you delete all the contents of a directory without deleting the directory itself? I want to basically empty a folder yet leave it (and the permissions) intact.

Swift 2.1.1:

public func deleteContentsOfFolder()
{
    // folderURL
    if let folderURL = self.URL()
    {
        // enumerator
        if let enumerator = NSFileManager.defaultManager().enumeratorAtURL(folderURL, includingPropertiesForKeys: nil, options: [], errorHandler: nil)
        {
            // item
            while let item = enumerator.nextObject()
            {
                // itemURL
                if let itemURL = item as? NSURL
                {
                    do
                    {
                        try NSFileManager.defaultManager().removeItemAtURL(itemURL)
                    }
                    catch let error as NSError
                    {
                        print("JBSFile Exception: Could not delete item within folder.  \(error)")
                    }
                    catch
                    {
                        print("JBSFile Exception: Could not delete item within folder.")
                    }
                }
            }
        }
    }
}
