Advanced SwiftUI Animations — Part 4: TimelineView Announced at WWDC 21, SwiftUI's TimelineView is a view that updates according to a provided schedule. In this post, part of a series of posts on advanced SwiftUI animations, Javier explores this new view in detail. Despite it being two years since the last entry in this series, Javier remains excited about SwiftUI animations, and this comes across in this enthusiastic post.

What is new in SwiftUI after WWDC21 SwiftUI took another substantial and welcomed step forward this year at WWDC. Along with some expected improvements, such as the new refreshable ViewModifier, we also saw some less anticipated additions such as the new TimeLine View type. In this post, Majid Jabrayilov provides his summary of significant SwiftUI additions announced at WWDC21. Posted on June 19, 2021 | swiftui wwdc21
Avoiding having to recompute values within SwiftUI views SwiftUI is a fantastic framework, with its declarative approach removing a lot of the complexity that comes with orchestrating UI updates. However, this benefit also comes with the cost, as developers can't have complete control over when and how the code in a View body property will be executed. Here, John Sundell explains an issue this can cause, and provides some approaches he uses to mitigate it. Posted on June 13, 2021 | swiftui
Core Data In Memory Store Core Data uses an on-disk store by default, which can cause some unnecessary work when running tests on store-related logic. In this short post, Keith Harrison shows us how using an in-memory is more efficient for testing, while also speeding up SwiftUI previews. Posted on June 13, 2021 | core data swiftui
Simpler way to deal with hardcoded ViewModifer values in SwiftUI When working with SwiftUI, it's likely that at some point we will want to configure a property of our UI based on a conditional value. For example, setting a font color to red when an error occurs. However, as Daniel Tavares explains in this post, this can become cumbersome when we have a lot of UI properties that depend on conditional values. Luckily, Daniel has something which can help, and he shares it with us in this post. Posted on June 12, 2021 | swiftui
Introspect for SwiftUI A lot of SwiftUI View types are implemented on top of existing UIKit or AppKit types. Introspect is a library that allows us to access the underlying type of a SwiftUI view. This can be useful when we want to change some property of our UI which is not yet exposed via SwiftUI. Posted on June 5, 2021 | library swiftui uikit appkit
Abstracting Navigation in SwiftUI Currently, implementing navigation between SwiftUI views usually means adding navigation logic that is tightly coupled to a View's body implementation. However, there are things we can do to reduce this coupling, and in this post, Omar demonstrates an approach he uses to decouple navigation logic from Views using some abstraction.

Custom Property Wrappers for SwiftUI A Swift property wrapper adds a layer of separation between code that defines a property and code that managers how a property is stored. By creating custom property wrappers, we write the management code once when we define the wrapper, and then reuse this code when we apply the wrapper to properties. In this post, Dave Delong shares some useful property wrappers that he has come up with while working on SwiftUI. Posted on April 12, 2021 | swiftui property wrapper
