![]() Next, use a ternary conditional operation along with each state variable to animate the scale, opacity, rotation, offset, and anchor properties of the logo as well as the waves. toggle to switch them between the initial and final animation states. Then, add the state variable inside each animation and use. ![]() Set the duration and speed parameters for the easing equations. Visit Hacking with Swift to learn more about how to create implicit and explicit animations. Another way to add animations to a view is to use an explicit animation which animates views without attaching the animation to the views themselves. In SwiftUI, you can create implicit animations by attaching an animation modifier to the view you want to animate. The easing functions as easeInOut and linear. ![]() onAppear modifier, add an explicit animation using withAnimation and specify onAppear modifier is used to trigger animations automatically when the views it attaches to appear. The swing state is used to create the swinging effect of the logo, and splash scales the logo up and makes all the views disappear at the end of the animation.įollow the steps below to build the splash animation:Īt the beginning of your struct, declare the following three states as private and set their initial states to false.Īfter using SwiftUI layout views to arrange the Stream logo and the waves as shown in the Swift file called SplashAnimation.swift, define how you want the animation to be triggered using the. The move state variable is used to create the horizontal motion of the waves (the two blue, wave-like rectangles). To build the splash animation, we’ll use the move, swing, and splash states. When a state’s instance changes, it affects the layout, behavior, and contents of the view that has access to it. To change objects over time, they must be driven by a state variable. To animate anything in SwiftUI, you have to change objects over time. Create a new Swift file called SplashAnimation.swift and replace its content with the following code. In the Xcode assets library, you’ll find all the assets required to build this animation in the folder called LogoAnimation. (Check out our seamless looping animations video on YouTube to learn how theses assets were structured in Sketch.) The launch screen SwiftUI animation you will build in this section uses assets exported from Sketch. The launch screen is then replaced immediately with your app’s home screen. When users tap your app icon, it will display the launch screen first as it starts. This section teaches you how to create a fast and seamless animated launch experience. The way your application launches impacts how users feel about the app. With the project files downloaded, you’re ready to start creating your launch screen animation. You can clone the project’s repository, open it with Xcode( if you already have Xcode installed on your Mac), or download it as a ZIP file. The code for this tutorial is hosted on GitHub. If you're unfamiliar with SwiftUI, also be sure to check out our SwiftUI Chat App tutorial. Since this is the final installment of our prototyping in SwiftUI series, you should check out part one and part two before diving in. You’ll use our iOS Chat SDK sample application to get you up and running. When creating an extension, you add the word extension before the name.Part three of this tutorial will guide you through creating a splash screen animation, an onboarding animation for an empty messages screen, turn-taking animations in chat messaging, and animating emojis. Creating an extension in SwiftĬreating extensions is similar to creating named types in Swift. You can also use extensions to extend your own code and for code cleanliness. This enables you to insert your own code into existing system code to which you wouldn’t otherwise have access, such as the Foundation framework. We’ll demonstrate how Swift extensions work by building a simple workout tracking app.Įxtensions, well, extend existing Swift named types - i.e., structs, classes, enums, and protocol - so you can add more functionality to them. ![]() In this tutorial, we’ll take you through a basic overview of extensions in Swift.
