SwiftUI provides the FocusState property wrapper that works on all Apple platforms and allows us to focus on a particular view or check if that view is already focused. The usage is effortless.

Xcode users. If your Mac is getting unusually warm running Xcode 26.1 (17B55) and macOS 26.1 check the Console for MercuryPosterExtension.ips files filling the crash reports. In ActivityMonitor, "ReportCrash" will be burning up your CPUs. It's related to SwiftUI Previews. FB20986632

TIL that there is no “native” way to have duration time inputs in swiftui.
this led me to implement my own. i wanted stay away from the scroll-type inputs you see in apps like timer, because they seem awfully inefficient and demand A LOT of space.
i think it came out nice. wdyt?

Interesting. Simply displaying this table seems to be extremely expensive on the main actor and it prevents the chart from updating immediately, even though fetching the data only takes a few milliseconds. Is Table really that costly to render or am I missing something?

The SwiftUI framework introduced the onGeometryChange view modifier, which is backward compatible with iOS 16, macOS 13, tvOS 16, watchOS 9, and visionOS 1. It allows us to track geometry changes of any view in SwiftUI.

Checking if I get this right: a nonisolated non-Sendable class is safe to use as Observable for SwiftUI provided it is created inside the View, which locks it to the MainActor, so mutations to its state will also always happen on MainActor.
