ChordDefinitionView

public struct ChordDefinitionView: View

A SwiftUI View for a ChordDefinition

The View can be styled with the passed DisplayOptions and further with the usual SwiftUI modifiers.

The color of the diagram are styled with the .foregroundStyle modifier

  • The color of the diagram is the primary color.

  • The labels are the secondary color

Note

If you don’t attach a .foregroundStyle modifier, the labels are hard to see because the primary and secondary color are not that different.

The height of the View is just as needed

It will calculate all the bits and pieces based on the width and will be not a fixed height. As always, you can set the height with a modifier as it pleases you.

Best is to wrap the View in another View to attach any modifiers:

/// SwiftUI `View` for a chord diagram
struct ChordDiagramView: View {
/// The chord
let chord: ChordDefinition
/// Width of the chord diagram
var width: Double
/// Display options
var options: ChordDefinition.DisplayOptions
/// The current color scheme
@Environment(\.colorScheme) var colorScheme
/// The body of the `View`
var body: some View {
   ChordDefinitionView(chord: chord, width: width, options: options)
       .foregroundStyle(.primary, colorScheme == .dark ? .black : .white)
   }
}

If you want to render the chord for print; just set the style to ‘black and white’ and use ImageRenderer to get your image.
