Hi @longseespace, it's possible to use media files that have already been uploaded with the server-side SDKs (Python, Go, Node.js) or REST APIs using fileData in the Swift SDK, e.g.:

let content = try await model.generateContent(
  ModelContent.Part.fileData(
    mimetype: "image/jpeg",
    uri: "https://generativelanguage.googleapis.com/v1beta/files/some-hash"
  ),
  "What is in this image?"
)

Unfortunately, based on our current engineering plan and product backlog, there is no plan to support uploading files using the Swift SDK in the near term. As a potential alternative, the similar product Vertex AI for Firebase SDK supports media uploaded with the Cloud Storage for Firebase SDK. This guide shows how to use the two SDKs together: https://firebase.google.com/docs/vertex-ai/solutions/cloud-storage
