iOS v2.1.1

1. Overview

The iOS SDK now provides frame-level callbacks, an abort mechanism, and improved data models compatible with PMF Story output.

2. Key API Additions

2.1. onFrameCaptured Callback

Replaces onProgress with richer frame context.

public struct FrameCapturedCallback {
  public let progress: Float
  public let resultPMF: ResultPMF
  public let orientation: [Double]
  public let lux: Float
}

Usage:

readerView.onFrameCaptured = { frame in
    print("Progress: \(frame.progress), Lux: \(frame.lux)")
}

2.2. Abort Support

Added onAbort callback and SwiftUI binding for abort handling.

@State private var isAborted = false

ReaderViewWrapper(
    analyserConfiguration: config,
    onAbort: { model in
        // handle abort event with partial PMF Story data
    },
    isAborted: $isAborted
)

• Returns partial ResultModel containing collected pmfStory frames

• Aborted analyses cannot be resumed

2.3. ResultModel Update

ResultModel now includes a pmfStory array to store per-frame analysis data, removing deprecated base64 image fields.
