Usage

Vertical Stepper View

import StepperView

let steps = [ Text("Cart").font(.caption),
              Text("Delivery Address").font(.caption),
              Text("Order Summary").font(.caption),
              Text("Payment Method").font(.caption),
              Text("Track").font(.caption)]

let indicationTypes = [StepperIndicationType.custom(NumberedCircleView(text: "1")),
                        .custom(NumberedCircleView(text: "2")),
                        .custom(NumberedCircleView(text: "3")),
                        .custom(NumberedCircleView(text: "4")),
                        .custom(NumberedCircleView(text: "5"))]
                        
var body: some View {
    StepperView()
        .addSteps(steps)
        .indicators(indicationTypes)
        .stepIndicatorMode(StepperMode.vertical)
        .spacing(30)
        .lineOptions(StepperLineOptions.custom(1, Colors.blue(.teal).rawValue))
}

Horizontal Stepper View

import StepperView

let steps = [

    StepperLineOptions.custom(1, Color.black),
    StepperLineOptions.custom(1, Color.black),
    StepperLineOptions.custom(1, Color.black),
    StepperLineOptions.custom(1, Color.black),
    StepperLineOptions.custom(1, Color.black)

var body: some View {
    StepperView()
        .addSteps(steps)
        .indicators(indicators)
        .addPitStops(pitStops)
        .pitStopLineOptions(pitStopLineOptions)
        .spacing(80) // auto calculates spacing between steps based on the content.
        .padding()
}

struct GithubPitstops {
    static var p1 = "Triage Notifications\nBrowse Repos\nCreate an issue"
    static var p2 = "Fork or Clone repo\ngit checkout -b branch\ngit stash"
