When loading a transparent png-texture onto a MeshResource the transparent parts of the texture would be rendered in black.

However, in iOS 13, adding a tintColor with an alpha of 0.9999 rendered correctly.

In iOS 14 however, this seems to be broken, so there doesn’t seem to be a way to render transparent textures at all.

Does anyone know a workaround?

As a workaround on iOS 14 beta 1, please try creating the SimpleMaterial using the SimpleMaterial(color:roughness:isMetallic:) initializer, and then changing the tintColor alpha to a value less than one.
