Mounting not working on iOS 12

[larrykollar]

iPad Air, running iOS 12.4.6. Looks like the file picker is coming up instead of the directory picker.

Working as expected on an iPhone 6s, iOS 13.3.1.

It works on my 2nd generation 11" iPad Pro running iOS 13.5 beta 3.

So maybe this only works in iOS 13+ ?

[tbodt]

Sounds likely. I never tested on iOS 12.

[larrykollar]

So does iOS 12 not support a directory picker?

[tbodt]

Not sure, haven't looked into it. If that turns out to be the case, I'll disable the feature on iOS 12.

@larrykollar @tbodt It is possible to open a directory on iOS 12, but the UI is different from iOS 13. For example, Textastic and Pythonista has supported that feature since iOS 12.

@tbodt If UIDocumentPickerViewController.allowsMultipleSelection is set to YES, mounting will work even on iOS 11 and 12. But it requires a little more work for multiple selection. For example, ignore folders other than the first one.
