2023-09-18 SwiftUI Separate toolbar

In SwiftUI, it's easy to just keep coding and dump everything in one view. Toolbars especially are "bulky", they take up a lot of lines, and are not regular views so syntax-wise, they're a bit of a bother to separate away. Here's an example of a bottom toolbar, to help you split up those big views.

    struct MainView: View {
        var body: some View {
            Color.blue
                .ignoresSafeArea(edges: [.top, .leading, .trailing])
                .toolbar {
                    ActionToolbar()
                }
        }
    }

    struct ActionToolbar: ToolbarContent {
        var body: some ToolbarContent {
            ToolbarItem(placement: .bottomBar) {
                 Spacer()
             }
            ToolbarItem(placement: .bottomBar) {
                Button(action: { print("Plus") }) {
                    Image(systemName: "plus.app.fill")
                        .resizable()
                        .scaledToFit()
                }
            }
        }
    }
