Joe Groff had a really awesome proposal last year, which is currently in a deferred state but will be resurrected in the future. </p>
<p>https://github.com/apple/swift-evolution/blob/master/proposals/0030-property-behavior-decls.md</p>
<p>It’s simply is a prioritization question, when this will happen. </p>
<p>That said, I’d expect some kind of <code>readOnlyLazy</code> property behavior that will match the mentioned <code>lazy let</code>.</p>

<div dir="ltr">It sure would be nice if the compiler supported lazy

<div>Seems like a nice performance win, lazy var is a pain because
you can't access arguments passed into a function without mutation
complaints.
