We will use it to persist the flashcards we create. It flips and gives an answer! The app is populated with sample cards stored in memory, and if we run the app and add new ones, they will disappear when we close the app. Do you remember who invented the compiler? Click the card. A click on any card transitions into a view where we can scroll the cards one by one. In the Previews section, there's a grid with some flash cards.

Throughout this session, we will leverage a new Xcode feature, embedded interactive live Previews for Mac. Open the starter project, and go to the ContentView file.

Hit pause now, and download the companion Xcode projects: an archive with the prepared starting point, and the finished one.

During this session, I will be building an app with you. It is available across all the platforms. I want this app to work everywhere: on Mac, iPhone, Watch, and TV, and SwiftData has my back. It will help to persist the flashcard decks, so I can open and click through them whenever I got a minute. For some time, I’ve wanted to make a tool that can help me remember dates and authors of great inventions, and SwiftData is perfect for this task. To see how SwiftData and SwiftUI play together, let’s build a flashcards app. To cover your basics, watch the 'Meet SwiftData' session first if you haven’t already. We will discuss the new SwiftUI features that allow for smooth integration with SwiftData models.

In today's session, let's see how to seamlessly integrate SwiftData in a SwiftUI app. Recently, we've introduced SwiftData, a new way to persist your model layer in Swift.

If you didn't want to go through and build the calculator step by step with me, then you can simply add the elements to your storyboard and copy and paste the full code into your view controller.Julia: Hello! My name is Julia. Label.text = String(previousNumber + numberOnScreen)Įssentially, this piece of code displays one of the miscellaneous buttons when it is pressed and proceeds to calculate the final answer and displays it on the label. Label.text = String(previousNumber - numberOnScreen) Label.text = String(previousNumber * numberOnScreen) Label.text = String(previousNumber / numberOnScreen) Remember, if you are ever confused about the code, I have left all my code for you to use on the last step of this Instructable.Īfter you have connected all the tagged miscellaneous buttons to their appropriate function, you can begin to insert the code into the 'buttons' function: This means that you simply bring the label into the function as a separate variable. Now, control, click, and drag the label into the program, but NOT into the function. Next, control, click, and drag each number button into the function that we just created.

Change the connection to 'action,' the type to 'UIButton,' the event to 'Touch Up Inside,' the arguments to 'Sender,' and its name to 'numbers.' You can change the name to whatever you would like but that means you would have to change the name again when calling the function later on in the program. Next, press control, click on the #0 button, and drag it onto the view controller. For example, the #0 button should have a tag value of 1, the #1 button should have a tag value of 2, the #2 button should have a tag value of 3, and so on. The tag should be 1 more than the actual numerical value. Open the attributes inspector and change the tag for every single number button.
