Hey @InvivoLuke I'm afraid we don't provide support for the iOS simulator with AVPro Video.

Thanks @MorrisRH ,

When was Simulator support dropped? It looks like it was added in 1.6.0.. https://forum.unity.com/threads/released-avpro-video-complete-video-playback-solution.385611/page-26#post-3011815

Would I be able to revert to an earlier version when it was supported?

We're trying to automate our CI/CD pipeline and be able to generate screenshots for a number of iOS devices, would be ideal to use the Simulator instead of having to run tests on physical devices.

It was dropped when we released version 2.0 back in January 2021. At that time the simulator didn't support Metal so we were unable to add it as a target (as with v2 we dropped support for OpenGL). A more recent complication came with the arrival of Apple Silicon which meant we were no longer able to embed the simulator code in the same plugin as the native device code.

There were some interface changes between v1 and v2 so you wouldn't be able to drop it in as is, we also no longer support it so there is a strong possibility it won't work as expected (or at all) anymore.

Issue #972 is open for adding the iOS simulator as an enhancement so if you'd like to register your interest there.
