Agenda
- Setup: Connecting Xcode to GitHub
- Please follow this link to create a new access token so that Xcode can push your commits to a remote on GitHub.
- Mr. Gordon will provide remaining instructions.
- Exercise: Modelling a Book Listing
- Create a new Xcode playground named Book Listing Exercise.
- Work with a partner to author a structure that could efficiently store the data shown in this online book listing.
NOTE
You can write down your rough ideas on the hard copies of this example that are being handed out.
- Remember: Don’t Repeat Yourself
- Use strategies we have discussed to avoid repeatedly defining similar fields.
- Exercise: Stopwatch
- Learn how to reproduce the interface of a real iOS app.
NOTE
Aim to finish this activity today if you have not done so yet.
- Exercise: Reminders App
- Create a new project for iOS named Reminders App.
- Work alone or with a partner to analyze this interface and then apply what you learned from reproducing the Stopwatch app to reproduce this interface.
- Focus on the main portion of the interface at first – that is, the list.
- Then, use SwiftUI Views Mastery, and look up the
NavigationStackstructure (pages 313 to 321) for examples of how to add:- a navigation title
- toolbar items (also see pages 681 to 684)
TIP
Do not worry about items like the battery icon, WiFi status, or cellular network – these are provided in a real app by the operating system and you do not have to worry about adding these to an interface as an app developer.
Things to do before our next class
- Take half an hour to make further progress on the activities from today’s class, if you did not finish up while in class.
