![]() ![]() When designing the navigation for your SwiftUI app, you must create a navigation pattern that helps the user move confidently through the app and intuitively perform tasks. Open WelcomeView.swift, and you’ll see the view includes a named flightInfo that holds this mock data for the app. You’ll be using this mock data through the next several chapters while building out this app. #Swiftui tabview selected tab generator#The class uses a seeded random number generator to produce a consistent set of flight data every time with only the start date changing.Īlso open and examine FlightInformation.swift, which encapsulates information about flights. The FlightData class generates a schedule for fifteen days of flights with thirty flights per day starting with today’s date using the generateSchedule() method. Open FlightData.swift, and you’ll find the implementation of the mock data for this app. ![]() For this app, though, you’ll be using mock data.Įxpand the Models folder in the app. In a real-world app, you would likely get the flight information from an API through Combine. In this chapter, you will build out the navigation for this app. Open the starter project for this chapter you’ll find a very early version of an app for an airport. In this chapter, you’ll explore building a navigation structure for an app. SwiftUI provides a unified interface to manage navigation while also displaying data. #Swiftui tabview selected tab how to#The navigation you design has to balance many needs: you need to display data logically to the user, you need to provide a consistent way to move between views, and you need to make it easy for the user to figure out how to perform a particular task. It’s a rare app the one that can work with only a single view most apps use many views and provide a way for the user to navigate between them smoothly.
