Cannot select TSV file from file Importer

Hello there, everyone. I have been having problems recently with add a file type as a supported type to my app that I intended to utilize as a way to allow users to share directly from my app, but things are not going so well.

Currently, the application supports JSON and QIF imports, but Air dropping from the app is not supported unless I utilize the proxy transfer representation, so I decided to add TSV support and got the stuff responsible for rendering my data as a TSV string and parsing a TSV string to my model to work.

However, the reading of TSV files seems to only work when sending the TSV file over via AirDrop and I cannot select the TSV file when using the file importer without implementing it as if it were a custom format, which should be unnecessary because it is a system defined type and I am utilizing the UTF-8 type in the plist file.

Does anybody what I need to do to fix this?
