imagePlaygroundSheet(isPresented:concepts:sourceImage:onCompletion:onCancellation:)

Declaration

@MainActor @preconcurrency func imagePlaygroundSheet(isPresented: Binding<Bool>, concepts: [ImagePlaygroundConcept] = [], sourceImage: Image? = nil, onCompletion: @escaping (URL) -> Void, onCancellation: (() -> Void)? = nil) -> some View

Parameters

• isPresented:

  A binding to a Boolean value that determines whether to display the sheet.

• concepts:

  An array of initial concepts (text descriptions, concepts extracted from text, drawings) that describe the expected contents of the image. The person reviewing the image can change these prompts inside the creation UI.

• sourceImage:

  Specify an existing image to use as source input for creating the new image. The person viewing the sheet can override the image you provide, and choose different images and concepts inside the creation UI. If you don’t provide a starting image, the system creates the new image using only the contents of the concepts parameter.

• onCompletion:

  The block to receive the generated image. The block has no return value and receives the following parameter:

  url

  A URL with the path to the image. The system saves the file at a temporary location inside your app container. Move the file to a new location if you intend to keep it after the dismissal of the sheet, or remove it if you don’t. After executing this block, the system automatically dismisses the sheet.

• onCancellation:

  The block to execute when the person exits the creation UI without choosing an image. After executing this block, the system automatically dismisses the sheet.

Discussion

Add this modifier to a view to display the system’s image-creation sheet. When the variable in the isPresented parameter is true, the view presents the sheet. Present the sheet in situations where someone might want to generate a new image for their content. When configuring the sheet, specify an optional starting image and text description to use to create the initial image.

While visible, the sheet allows people to experiment with the contents of an image before returning it to your app. The person viewing the sheet can accept the image they created or cancel the operation. When they make their choice, the system executes the appropriate block.

You can use this modifier only if the device supports creating new images. Check the ImagePlayground/SwiftUICore/EnvironmentValues/supportsImagePlayground environment variable to determine the availability of the feature. The following code creates a button to display the sheet only when the feature is available:

@State private var showSheet = false
@State private var createdImageURL: URL? = nil
@Environment(\.supportsImagePlayground) private var supportsImagePlayground
// ....

if supportsImagePlayground {
  Button("Show Generation Sheet") {
    showSheet = true
  }.imagePlaygroundSheet(isPresented: $showSheet) { url in
      createdImageURL = url
  }
}
