Hi everyone, I’m having trouble getting the new glassEffect() modifier to render correctly in SwiftUI. No matter what I try, it just appears as a solid white background (instead of translucent glass). This happens both in Beta 1 and Beta 2. My setup: • Mac mini (M4 chip) • macOS 15 Beta 2 (Tahoe) • Xcode 16 Beta 2 • Samsung Odyssey G9 57” monitor (super ultrawide) • Using Preview in SwiftUI (not the Simulator) Even when I use Apple’s default demo code like: Text("Hello World") .padding() .glassEffect()

Hi everyone, since updating to Xcode 26 Beta 3, I’m seeing some really strange behavior. I just changed the color of a Color asset in my SwiftUI view – literally just switched from one named color to another – and suddenly: • Previews stopped working completely, with vague or no error messages. • Even when I changed the color back to what it was before, the previews still refused to build. • In addition, Xcode no longer restores the open tabs/windows when reopening the project. It just shows a blank editor every time I open it. This all happened without touching any project settings or code structure – just a simple color swap. Has anyone else run into this with Xcode 26 Beta 3? Would love to know if it’s a known bug or if there’s a workaround (besides nuking Derived Data, which I’ve already tried). Thanks!

Hi everyone, I’m trying to recreate the beautiful transition effect used in Apple’s built-in Calendar app — specifically the one where, when you tap on a month, you’re “pulled into” the next view, and when going from month to day, the views seem to slide vertically, almost as if one is pushing the other off-screen. It’s not the standard right-to-left slide you get with NavigationStack or NavigationLink, and it feels much more immersive and dynamic. I’ve been experimenting with .matchedGeometryEffect and .transition(.move(...)) in a ZStack, and while I can replicate some aspects, I’m still missing that fluid, directional pull that makes it feel like you’re diving deeper into the calendar. I’m also unsure how much the view structure between the source and destination needs to match for the matchedGeometryEffect to really shine. Does anyone know what APIs or techniques Apple might be using internally to build that kind of animation? Is there a clean way to achieve something similar using SwiftUI as of iOS 17 or 18? Would love to hear if someone here has successfully replicated this or has tips on best practices. Thanks in advance!
