Unfortunately, the 2014 Metal release is not comparable to 2016 Vulkan release.
Metal from 2014 had a lot of assumptions (for example, that the GPU shares memory with CPU), so it could be released earlier due to being simpler. That's why it was supported only on iOS.
And that's why there were more Metal releases and refinements. Apple had to make improvements to make it equal in its capabilities to Vulkan 1.0 and DX12.
