Zac Hall (MacRumors):

The update also adds these changes:

• Refreshed look with Liquid Glass.
• List filtering by Unwatched, Bookmarked, and Downloaded, and preferred topics.
• Improved reliability of image capture during enrollment.
• Bug fixes and various other enhancements.

Steve Troughton-Smith:

[It] has been ported from Catalyst-based to AppKit-based (it is a SwiftUI app in either case). Expect a whole new set of idiosyncrasies along with whatever new improvements/bugs it introduces.

(You can now fullscreen videos properly, for example)

I went to launch the old app so that I could compare it before downloading the new one and realized that I had deleted it because that was the only way to prevent WWDC session links from opening in the app instead of in Safari. So I don’t have a good feel for what’s changed aside from the list filtering mentioned above and the better support for full screen videos.

The current universal links behavior is that if I click a link within Safari it stays in Safari and shows a banner for opening the link in the Developer app. That’s an improvement. If I click a link outside of Safari, it opens the Developer app. There’s no command in the app to open the current session in your browser, though you can use Edit ‣ Copy Link and then paste it.

Previously:

• Apple Developer App 10.8
• Disabling Universal Links

Update (2026-06-04): I’ve deleted the Developer app again. I can’t stand how just having it installed makes NetNewsWire open links from Apple’s developer news site in the app instead of in my browser.
