Declaration

Swift

                    onAppear

Declaration

Swift

public var onAppear: LifecycleCallback?


                    
                    
                    onDisappear

Declaration

Swift

public var onDisappear: LifecycleCallback?


                    
                    
                    init(onAppear:onDisappear:wrapping:)

Declaration

Swift

public init(
    onAppear: LifecycleCallback? = nil,
    onDisappear: LifecycleCallback? = nil,
    wrapping: Element
)


                    
                    
                    content

Declaration

Swift

public var content: ElementContent { get }


                    
                    
                    backingViewDescription(with:)

Declaration

Swift

public func backingViewDescription(with context: ViewDescriptionContext) -> ViewDescription?


                    
                    
                    onAppear(_:)

Adds a hook that will be called when this element appears.

Callbacks run in depth-first traversal order, with parents before children.

Declaration

Swift

public func onAppear(_ callback: @escaping LifecycleCallback) -> LifecycleObserver


                    
                    
                    onDisappear(_:)

Adds a hook that will be called when this element disappears.

Callbacks run in depth-first traversal order, with parents before children. There is no guaranteed order between disappearance callbacks and backing views being removed from their superviews.

Declaration

Swift

public func onDisappear(_ callback: @escaping LifecycleCallback) -> LifecycleObserver
