What happened?

We are seeing crashes in the map rendering on iPhone and iPad devices (including simulators) with iOS 15 when using the latest MapLibre release (6.9.0).

I already saw an issue with the same error "Base Vertex Instance Drawing is only supported on MTLGPUFamilyApple3 and later."
#2447

It seems like it was fixed in 6.5.0 release and yes this crash is not happening on this version but exists on all higher versions.
I was trying to figure out if I can rollback to lower version and it reporoduces on all versions starting from 6.5.1 to latest 6.9.0

Steps to reproduce

Render a map
The app crashes

Relevant log output

MTLValidateFeatureSupport:4854: failed assertion `Base Vertex Instance Drawing is only supported on MTLGPUFamilyApple3 and later.'

Additional context

On 6.5.0 with iOS 15 there is no crash but map has some artefacts

@kylba4enko Are you seeing this crash on real devices as well?

May be caused by https://github.com/maplibre/maplibre-native/pull/2518/files

[kylba4enko]

Yes, also on real device iPhone 7 with iOS 15.8.2

[kylba4enko]

On iOS 18 everything works fine on real devices and simulators.

Interesting. We might have to update the check to include not only device support but also iOS version.
