Since this week has kept me extremely busy with packing our things, selling furniture, and wrapping up any loose ends before relocating back to Estonia from Japan after 4.5 years, I am going to use this week’s blog post for highlighting a new Swift 5.8 language feature. I welcome this change since how hard I try there still will be cases where I need to capture self in closures.
The language feature we are talking about is of course SE-0365: Allow implicit self for weak self captures, after self is unwrapped. Which means that if we capture self weakly in a closure, use guard let self then there is no need to write self. inside the closure any more.
Let’s take a look at a concrete example from my SignalPath app. It is a tiny change, but I feel like it makes a lot of sense. Especially because I already have explicitly handled weak self with guard let.
