@State var selectedFilter: filter?

Picker("", selection: $selectedFilter) { ForEach(AllFilters) { filter in Text(filter.Title).tag(filter as filter?) } }

You click on a different item and it does not change! https://ibb.co/Sd0jHkm

Thanks!!

Make you @State var selectedFilter: filter non optional and provide inital value if possible. It'll work just fine. Or provide details for type filter as well if you navigate to this particular view by passing this type... to see how the data flow is happening.
