Localframe for iOS

Localframe is a simple SwiftUI image generation app for iOS 26, powered entirely by Apple’s on-device Foundation Models via Image Playground. Designed for demonstration purposes, Localframe enables fast, private, and completely offline image creation — no internet connection or server required.

Localframe showcases how to integrate Apple’s Image Playground framework into a native iOS experience using SwiftUI and the new Foundation Models tools.

⚠️ Disclaimer: This app is for demonstration purposes only and is not production-ready. Output generated by the local image generation model may be inaccurate, incomplete, or misleading.

✨ Features

• 🖼️ On-device Image Generation: Uses Apple’s local Image Playground framework.
• 🔐 Privacy-first: All prompts and generated images stay on your device. No data is sent to the cloud.
• ⚡ Fast & Offline: Images are generated locally with no need for internet access.
• 🧑‍🎨 Minimalist Prompt UI: Clean SwiftUI interface for crafting prompts and viewing output.
• 🗑️ No storage: Generated images are not saved after closing the app.

🛠 Manual

• Import the Library: To work with Foundation Models, you must import the library in every file where you intend to use them. Go with:

  import ImagePlayground

• Create an ImageCreator object: To start image creation, you need to create an ImageCreator object. In case of failure you will get an ImageCreator.Error:

  do {
      try await self.imageCreator = ImageCreator()
  } catch {
      self.creatorError = error as? ImageCreator.Error
  }

• Generate an Image: To create images with the model, simply call the method and pass in your text prompt (as a String) along with the desired style (as ImagePlaygroundStyle).

  let images = imageCreator!.images(
      for: [.text(self.prompt)],
      style: self.generationStyle,
      limit: 2)

• Save Images: To display the generated images, store them in an array:

  for try await image in images {
      if let generatedImages = generatedImages {
          self.generatedImages = generatedImages + [image.cgImage]
      } else {
          self.generatedImages = [image.cgImage]
      }
  }
