I'm watching the session video "What's new in Xcode 26" and when I try out the new #Playground macro (in the context of a local package in my project) I see only this activity indicator for about 10-15 minutes: Eventually I do see this error: Despite the error, my local package does not import SwiftUI and has no dependencies other than Foundation. I checked the Xcode 26 release notes and I don't see this issue mentioned. A clean build of my project takes 55 seconds. Is it expected behavior that #Playground would require 10+ minutes to spin up? Is there anything I can to do make the new #Playground macro work correctly? Thank you.
