"Create folders" Cannot run

[ZackDT]

I imported the ChartingLibrary using "create folder" and it no longer works correctly

I think something changed in Xcode 16.1 when adding folders. Here's either the right fix or a workaround: With 'ChartingLibrary' selected like in your screenshot go to the File Inspector on the right side of Xcode and change Build Rules to 'Apply once for folder'. Below that for Target Membership click + and re-add your project as a target and that should remove the errors. The source needs to be loaded as 'ChartingLibrary/index.html'.
