Fatal Error in Swift Playground Description I'm experiencing a catastrophic error when importing Package Dependency in any Swift Playgrounds that has icon or name that caused the whole Playground won't work anymore with error messages below. I'm current running macOS Sequoia 15.3 (24D60) and Swift Playgrounds 4.6.1. They're all up-to-date. Reproduction Open Swift Playgrounds and and create a new project. Import a package dependency https://github.com/simibac/ConfettiSwiftUI.git Rename the project and add an icon Then you should able the reproduce the problem. I strongly believed that this is a serious bug. You'll find that Assets in the left column are disappeared and appeared Assets.xcassets, you're unable to reveal the Dependency in the column like the reference picture above. The whole Playground is destroyed now and unable to work anymore.

I'm unable to rename my Swift Playground or add/change the app icon when I imported a package dependency after upgraded my Swift Playgrounds App to the newest version. Every time I tried to do that, the whole project will be destroyed and showed error message below. I wonder if anyone have same experience with me or someone can tell me the solution, it terrifies me and I'm worried that I'll be unable to submit my project on time because of that.
