Custom file types with custom file extensions cannot do not work with the iOS file picker

[Porygon-Axolotl]

Describe the bug

I am developing a game and it uses a custom file type to load levels. When i open the file ios picker in the game the .rsplev file is greyed out, unlike when its normally sideloaded where the file with the .rsplev file extension isnt greyed out and is able to be picked.

Instructions to reproduce

Open the iOS file picker and try choose a file that has a custom filetype

What version of LiveContainer are you using?

Version 2.0-release (main/2d7bbe4)

Other info

At first I thought it was an issue with my game but then i realized it only happened with livecontainer. I honestly have no idea if it’s fixable (i don’t know much about iOS development) since the way i got the file extension to work is by modifying my info.plist file. I modified the key UTExportedTypeDeclaration inside the info.plist so i don’t know if there is another way to allow other file types without modifying livecontainer’s info.plist. Sorry if its an impossible fix

I think you should try [UTType typeWithFilenameExtension:@"rsplev" conformingToType:UTTypeData]

I don't know if im doing something wrong but i still can't select a file with my custom file type. (Version 2.1.2-release (main/345097c)) https://github.com/user-attachments/assets/39f82739-df27-432a-8144-c8974f3b8273

Can you provide an ipa and a rsplev so I can diagnose what's wrong?

It does require an account to use though. Hope you dont mind

OK, it turned out that Unity used a deprecated API -[UIDocumentPickerViewController initWithDocumentTypes:inMode:] which I forgot to hook. I will fix this later.

Fixed now. Try this build https://github.com/hugeBlack/LiveContainer/actions/runs/11007432755
