SwiftUI Previews @ Apple

[Kevin Cathey @kbcathey]

@wvabrinskas In Xcode’s Settings, go to Intelligence, then “Add a Model Provider”, then enter https://t.co/OQAuHlf0Ep and enter your API key. There is a bug where you might have to restart Xcode if the list of models doesn’t show up right away.

Note: to try out generative intelligence features in Xcode 26 you also need to be running the macOS 26 beta

[Kevin Cathey @kbcathey]

@DonnyWals It is in the new Xcode 26 beta when running on the beta of macOS 26

[Kevin Cathey @kbcathey]

@mwstrmnn It is only available when using macOS 26, have you had a chance to update to that beta?

The SwiftUI tools team is hiring! We are looking for engineers passionate about the intersection of UI design, UI frameworks, and applying techniques like ML to guide building great user experiences. If this sounds interesting, please apply! https://t.co/QrblG5s1yY

[Kevin Cathey @kbcathey]

@pwnies Could you be more specific? What kinds of issues are you seeing?

[Kevin Cathey @kbcathey]

@azamsharp Unfortunately yes, this is a known issue with previews.

@thecraftybrit Yay!

[Kevin Cathey @kbcathey]

@thecraftybrit That's good to know! We look forward to getting the preview diagnostics, thanks for helping us make previews better!

[Kevin Cathey @kbcathey]

@bradleybernard This happens if your view, e.g. `SettingsView` has an implicit stack. i.e. the `body` had three views without an enclosing container like VStack, Group, etc. Workaround: wrap your preview in a Group in `previews`

This is fixed with the new Preview macro API in Xcode 15.

This might be worth posting again: The SwiftUI Previews team is hiring! We love sitting at the intersection of tools, languages, frameworks, & the OS.

If you love thinking about how we all write software and love to learn, please apply or DM! https://t.co/pdUzDxjb7l

[Kevin Cathey @kbcathey]

@jamesdempsey I think I fixed it now :)

@MuseumShuffle Thanks for posting and sending in the feedback. Can you try closing the "Remote.swift" file and just having the single widget file open?

[Kevin Cathey @kbcathey]

@sayhellobryan Glad to hear! Please keep the bug reports with previews diagnostics headed our way. We read every one of them.

[Kevin Cathey @kbcathey]

@sayhellobryan Another abstraction that works well is to put all of your UI code in a leaf module. This forces you to minimize what you can pass into and be intentional about design. And then it means you can refactor your app without having to immediately update your previews.

@kyleve @NachoSoto Ouch, yeah, there are definitely known issues related to nested types, especially combined with generics. Sometimes this can be worked around (yes, I know it's just a workaround) with well placed `typealias`'s that help the inner types know how to find sibling nested types
