![]() To fix this issue once and for all, you’re going to do some work inside the viewDidLoad() method in ViewController.swift. Take it from me - that kind of thing is hard to remember, especially when the project becomes bigger and you have dozens of view controllers to worry about, or when you haven’t looked at the code for weeks. You’d have to remember to also fix the code to give currentValue a new initial value. What if you decide to set the initial value of the slider in the storyboard to something other than 50 - say, 1 or 100? Then currentValue would be wrong again because the app always assumes it will be 50 at the start. That’s great, but you can still improve on it a little. You completed storing the value of the slider into a variable and showing it via an alert. Calculating the points scored: Determine how many points to award to the player, based on how closely they positioned the slider to the target value.Display the target value: Display the generated target number on screen.Add rounds to the game: Add the ability to start a new round of the game.Generate the random number: Generate the random number to be used as the target by the game.Improve the slider: Set the initial slider value (in code) to be whatever value was set in the storyboard instead of assuming an initial value.This chapter takes care of a few other items from the to-do list and covers the following: That already knocks quite a few items off the to-do list. You’ve built the user interface for Bullseye and you know how to find the current position of the slider. 53.4 Removing the default checklist items.52.2 Giving checklist rows their own view.52.1 Changing how the user changes checklist items.50.6 What happens when you launch an app?.50.5 Connecting the view to the ViewModel Topic: Xcode Tip: How to set up an app icon for iOS App in Xcode 10 2019.Generate icons and images for mobile apps, Android and iOS.47.4 When to use structs and when to use classes.You can select the image by adding the following to a job in config.yml : macos: xcode: 10.3.0 Changes: Xcode 10.3 Build version 10G8 Important: We have the default set of simulators installed on this image (iOS/tvOS 12.4, watchOS 5.3).
