The title says it all, I'm using SwiftUI for multiplatform app, and I'm using ScrollView in it.

My app has player bar which tracks the AVPlayer's current time. I made it using .offset(y:). The problem here is that whenever I change offset, the scroll gesture suddenly doesn't work on macOS.

But weirdly, it works on Mac Catalyst version.

The source code is on GitHub.

I tried using Animation, but it made the player bar and music out of sync.

So right now I made a publisher based on AVPlayer's addPeriodicTimeObserver and receiving the time from AVPlayer but now the scroll doesn't work as expected.

@yunho0508 Do you get the same results with just the relevant code in a small test project? If so, please share a link to your test project. That'll help us better understand what's going on. If you're not familiar with preparing a test project, take a look at Creating a test project.
