> We were alerted today by an indie game studio that one of their iOS games is now rejected by Apple over its MoltenVK usage. Specifically, the game was rejected for "non-public API" usage. Apple's rejection letter cites the use of non-public interfaces around IOSurface, which is used directly by MoltenVK.
If this game used Metal directly with no involvement of MoltenVK at all, it’d still get rejected if it as long as that IOSurface private API is in use. The title is borderline clickbait.
Same reason they refused to provide cross platform Vulkan to begin with. And it's not a good reason obviously.
The article omitted the critical detail about which private API was used. I have received one of those letters before and they should contain those details. The fact that the article omitted that information makes it sound like they want to start a controversy instead of admitting a library developer probably made an easily remedied mistake. They were hoping for low-information-high-opinion internet audience to drive traffic.
