title: Is it possible to use Metal data types in Objective-C?
body: <p>I want to use some of the vector data types defined in Metal (such as <code>uint2</code>, <a href="https://developer.apple.com/library/ios/documentation/Metal/Reference/MetalShadingLanguageGuide/data-types/data-types.html#//apple_ref/doc/uid/TP40014364-CH2-SW1" rel="nofollow">docs</a>) in Objective-C for my iOS app.  However, I haven't been able to find any information about whether or not this is possible.</p>
