   I only need to see your usage of PickFile function. You can copy your C# code here.

   Hello.

   First of all, thanks for the hard work and the code quality. I have dug a bit to understand what UnityNativeFilePicker was doing exactly and it is very clear.

   I am having the same issue so I am updating this post as I assume @nextechar-hardik wont.

   I have an abstraction layer on top of UnityNativeFilePicker so I can use different methods to pick files (or pick files on other systems), so I won't give the full code as it is not related, but it ends up calling the following:

   string[] extensions = new [] {
       NativeFilePicker.ConvertExtensionToFileType("png"),
       NativeFilePicker.ConvertExtensionToFileType("jpg"),
       NativeFilePicker.ConvertExtensionToFileType("jpeg"),
       NativeFilePicker.ConvertExtensionToFileType("gltf"),
       NativeFilePicker.ConvertExtensionToFileType("glb")
   }
   NativeFilePicker.PickFile(path => Debug.Log(path), extensions);
   

   Only png, & jpeg files can be picked. GLTF & GLB are not displayed.

   I found the following post that might be useful:

   It seems a deprecated method is used to acquire UTType:
   

   UnityNativeFilePicker/Plugins/NativeFilePicker/iOS/NativeFilePicker.mm

   Line 100 in da3f797

   CFStringRef fileUTI = UTTypeCreatePreferredIdentifierForTag( kUTTagClassFilenameExtension, (__bridge CFStringRef) extension, NULL );

   
   The initializer is now the correct way to do this:
   https://developer.apple.com/documentation/uniformtypeidentifiers/uttype-swift.struct/init(tag:tagclass:conformingto:)

   I made a test in xcode, without deploying to anything. Using a basic Swift project:
   

   Using the new initializer seems to fix the issue.

   Nevermind, it works with the deprecated method too. My code was just garbage.
   I'll try to find another answer to why it fails then.

   GLB and GLTF don't exist in the filetype lists I've posted: https://github.com/yasirkula/UnityNativeFilePicker?tab=readme-ov-file#a-importing-files. The only possible solution is to allow picking all files and then check the returned files' extensions in the callback function.
