An existential container in Swift is a concept related to how Swift handles types and values, particularly when dealing with generics and protocols. It is not explicitly mentioned in the provided context from the WWDC sessions. However, the context does discuss various types of containers in SwiftUI, such as custom container views and model containers in SwiftData.
For example, in the session "Demystify SwiftUI containers," there is a focus on building custom container views in SwiftUI, which can support various capabilities like sections and custom modifiers. These containers use a trailing view builder closure to wrap their content, allowing for both static and dynamic content composition.
If you are interested in learning more about SwiftUI containers, you might want to check out the session Demystify SwiftUI containers (00:00:07) for an introduction to building custom container views in SwiftUI.
