macOS remove today view widget from today view

[abcdefg12345]

i was experimenting with today view extensions in Xcode and i accidentally added a widget to today view to see if it works and what i ended up with is a widget that has all the layout correctly set but cant click on any buttons and i don't know how to remove it from there, i deleted the project that i made with the today view and emptied the DerivedData folder in library/developer/xcode but it still shows up there

any way to permanently remove it and why didn't any buttons respond to my clicks when i click them while it works perfectly with the simulator

I googled for the following search terms, which are essentially the important keywords in your post:
remove xcode widget

On the first page of results is this:
App Extension Programming Guide: Today

After users install an app that contains a Today widget, they can add the widget to the Today view. When users choose Edit in the Today view, Notification Center reveals a view that lets users add, reorder, and remove widgets.
​

If you haven't used Edit in the Today view, then try that. If you have used it and still couldn't remove your widget, then clearly state that.

I recommend reading the complete App Extension Programming Guide, which includes Today widgets, so you know all the fundamentals.

I also suggest that you practice using such widgets with a known-working app that has a widget. Make sure you know how to manage the known-good widget before making your own.
