Clock UI for SwiftUI

This library has been tested

• ✅💻 macOS Catalina 10.15.3
• ✅📱 iOS 13.3

Bind a date

struct ContentView: View {
    @State private var date = Date()

    var body: some View {
        ClockView().environment(\.clockDate, $date)
    }
}

Simply set .environment(\.clockDate, $date) $date has to be a binding. If you want something constant (just for showing the time), you could pass .constant(yourDate)

• Arms move when date are set (take hour and minute in account)
• Move the Arms change the date (hour and minute depending on wich arm you've moved)

Change Clock style

There is 4 different clock style:

Style	Picture
Classic
Art Nouveau
Drawing
Steampunk

To set the style: .environment(\.clockStyle, .steampunk) for Steampunk style for instance.

struct ContentView: View {
    @State private var clockStyle: ClockStyle = .classic

    var body: some View {
        ClockView().environment(\.clockStyle, clockStyle)
    }
}

\.clockStyle is typed as enum ClockStyle which is Identifiable, CaseIterable, and has a convenient method to get the description (in English): public var description: String

It's very useful when you want to iterate over this to let the use choose the clock style, for instance you can easily do something like this:

struct StylePicker: View {
    @Binding var clockStyle: ClockStyle

    var body: some View {
        Picker("Style", selection: clockStyle) {
            ForEach(ClockStyle.allCases) { style in
                Text(style.description).tag(style)
            }
        }
        .pickerStyle(SegmentedPickerStyle())
    }
}
