ThemePicker in iOS Scrumdinger tutorial not displaying ThemeView colors

Question

I looked through the completed version of this lesson, and it also does not show the background color. I'm wondering if this has to do with different versions of Swift/XCode

Expected view

Actual view in project

Answer 1

If you use the latest version of iOS, in the ThemePicker file you can try to chose picker style. This is how it will looks in iOS 16.2

var body: some View {
    Picker("Theme", selection: $selection){
        ForEach(Theme.allCases) { theme in
            ThemeView(theme: theme)
                .tag(theme)
        }
    }
    .pickerStyle(.navigationLink)
