Re: [swift-users] Assigning a variable to itself

I’ll leave it to others to explain whether this is the intended behavior, but the further I get from properties being idempotent, the more grief I’ve had. Especially when (as I assume is your real use case) I tried to assign something to itself to force a didSet {} during viewDidLoad(). If I m

[swift-users] Chaining struct-mutating funcs

Swift 3 as of Xcode 8.0b4 TL;DR: I have a struct value type backed by a copy-on-write mutable buffer. You use it to perform arithmetic on the buffers. The most expressive way to do this efficiently is to chain the arithmetic operators so each mutates the same buffer. Swift does not like to chai
