Diagnostics I'm able to build my project and run it on a simulator. I generate my project with xcodegen which I've added a bunch of things to in attempting to fix this but failed!

Error Diagnostics I'm able to run my app on a simulator, but previews aren't working even for the simplest test preview. I build my project with XcodeGen.

I'm testing my App and the preview in Xcode keeps refreezing by itself preventing me from testing my code. It refreshes about once a second despite me not doing anything. Any ideas? Thank you!
