I'm trying to duplicate the Picker example at 31:39 in the "What's new in SwiftUI" WWDC 2023 video at https://developer.apple.com/wwdc23/10148. My code is at https://github.com/mvolkmann/PickerStyleDemo/blob/main/PickerStyleDemo/ContentView.swift. The attached screenshot shows what I get. Note that I don't see "tag" SF Symbol for each option like the WWDC video shows. Am I doing something wrong?

In a Swift Chart that listens for drag gestures in order to display a RuleMark with an annotation, the y-axis scale changes while dragging which causes the entire chart to jump. I have a small code example that demonstrates this at https://github.com/mvolkmann/ChartJump. See the two screenshots there.
