I am using <code>CAMetalLayer</code> to draw onto a UIView. The compiler throws a warning that <code>CAMetalLayer</code> is only available on iOS 13.0. The docs however say <code>iOS 8.0+</code>. Can I ignore this warning? I only have iOS 13.0 devices here and we'd like to support 12 and 11, too. <img src="https://i.stack.imgur.com/AvynR.png" alt="enter image description here">

<code>CAMetalLayer</code> is actually available on iOS 8.0+, I can confirm this. This warning is a known Apple mistake, you can ignore it.

CAMetalLayer is only available on iOS 13.0
