John McCall (forum):
However, this approach has significant problems. The biggest is that the get accessor has to return an independent value. If the accessor is just returning a value stored in memory, which is very common for data structures, this means the value has to be copied.

This vision document lays out the design space of accessors for the next few years, as Swift continues to advance its support for non-Copyable and non-Escapable types. It explains Swift’s basic access model and how it may need to evolve. It explores what developers need from accessors in these advanced situations. Finally, it discusses different kinds of accessors, both existing and under consideration, and how they do or do not fit into the future of the language as we see it.

The yield accessor is the natural most-general model of a borrowing read access. It is a coroutine function which yields a borrowed value and can then do arbitrary finalization when resumed.
The borrow accessor is a specialization of that model which expresses that no finalization is required. It is an ordinary function that returns a borrowed value.

yield inout and mutate are both modification accessors.
[…]
unsafeAddress is functionally a borrowing read accessor. It is an ordinary function that returns an UnsafePointer<ValueType>.

Delta, the MacStories Selects App of the Year, received an important update today that allows users of the game emulator to support its development via Patreon from inside the app. Existing patrons can connect their Patreon accounts from Delta’s settings, too, allowing them to access perks like alternative app icons and experimental features.
This is a big deal that goes beyond the new features for Delta supporters. According to the app’s developer, Riley Testut, Delta is the first app he’s aware of in the U.S. App Store to include an in-app link that allows users to make purchases outside the App Store using Apple’s External Purchase Link Entitlement that was introduced in January.
I guess this is progress, but now Delta is responsible for regularly sending Apple a commission and financial reports.

Welcome to my new series on things I don’t understand about Apple’s premier user interface framework.

To be clear, these are things I don’t understand, not necessarily things that are “wrong.” They sure look wrong (or at least “suboptimal”) to me! But maybe there are good reasons, and I just don’t know them yet. SwiftUI experts and historians, please tell me!

I’ve been shipping apps to the App Store for well over fifteen years now, and although there are App Review horror stories aplenty, I’ve always hoped I’d never be in a position to write one myself.

What you just scrolled past was the history of my (eventually successful) attempt to get the new Mac version of our app — Cascable Studio — approved for the Mac App Store. The entire process took nearly a month, and we had to push an emergency build through in the middle there with some features stripped out to get something approved for launch.
[…]
We’re at version 7.0 now, and the iOS version of this app has been on the App Store since 2015. Indeed, most of the app was fine — this ordeal was all about one particular feature.
A feature that’d already been approved and on the App Store since 2019 in a different app of ours.

Anyway, I must’ve explained what Apple Events are to three separate people throughout this process. This did eventually get to someone technical up at the appeals board, but nobody having any idea what an “Apple Event” is really cannot have helped.
App Review doesn’t like apps that integrate with other apps, which is one of the best things about the Mac.
