Bookplayer: Playlist not sorted properly

• What is the current behavior?
  I have a playlist of files titled "Chapter 1", "Chapter 2", "Chapter 3", etc. When I try to sort them using the new sort feature added in v3.2.0 they are sorted as: "Chapter 1", "Chapter 10", "Chapter 11", "Chapter 2", instead of the correct order (like in Finder or Files.app)

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo / screenshot / screen recording of the problem.
  

• What is the expected behavior?
  For the files to be ordered correctly, like in Finder or Files.app

• What is the motivation / use case for changing the behavior?
  To be able to listen to audiobooks broken into multiple files in the correct order

• Please tell us about your environment:

  • Version of BookPlayer: v3.2.0
  • Your Device and its OS version: iPhone 6s, iOS 12.1

• Other information
  I think this can be solved by using the NSString.CompareOptions.numeric option to compare filenames when sorting the files

Are you sorting on filename or on title?

[halleygen]

Filename, but I just tried and sorting by the title doesn’t work properly either.

[ryantstone]

Ok. I’ll take a look. Thanks for pointing it out.

I ran into this while I was refactoring some things, turns out we had to use .numeric as an option for the NSSortDescriptor. The fix is included in the batch edit PR #289

This works great in the new update. Thanks for you hard work!
