AVAsset.LoadTracksWithMediaTypeAsync binding incorrect return type

[jaredmorley]

Apple platform

iOS

Framework version

net10.0-*

Affected platform version

VS2026 18.0.0, .NET 10.0

Description

It looks like the the binding for this method from the apple docs:
https://developer.apple.com/documentation/avfoundation/avasset/loadtracks(withmediatype:completionhandler:)
and here in the microsoft docs:
https://learn.microsoft.com/lb-lu/dotnet/api/avfoundation.avasset.loadtrackswithmediatypeasync?view=net-ios-26.4-10.0
is incorrect.

The return type should be avassettrack not AVMutableCompositionTrack

Steps to Reproduce

You can observe the behavior by reading the apple docs and the microsoft docs and see that the type is wrong.

Simply run the following:

var asset = AVUrlAsset.Create(NSUrl.FromString(videoUrl));

var sourceVideoTracks = await asset.LoadTracksWithMediaTypeAsync(AVMediaTypesExtensions.GetConstant(AVMediaTypes.Video));

var x = sourceVideoTracks[0];

Did you find any workaround?

I would suggest changing the return type to AVAssetTrack

Indeed, this looks wrong. A fix is in progress.
