In our app, we needed to use visionkit framework to lift up the subject from an image and crop it. Here is the piece of code:
if #available(iOS 17.0, *) {
let analyzer = ImageAnalyzer()
let analysis = try? await analyzer.analyze(image, configuration: self.visionKitConfiguration)
let interaction = ImageAnalysisInteraction()
interaction.analysis = analysis
interaction.preferredInteractionTypes = [.automatic]
guard let subject = await interaction.subjects.first else{
return image
}
let s = await interaction.subjects
print(s.first?.bounds)
guard let cropped = try? await subject.image else { return image }
return cropped
}
But the s.first?.bounds always returns a cgrect with all 0 values. Is there any other way to get the position of the cropped subject? I need the position in the image from where the subject was cropped. Can anyone help?

We are developing an app which uses AVCaptureSession. Here is a part of my code:
if context.config.basic_settings.auto_focus == 1 {
// 自動フォーカス
device.focusMode = AVCaptureDevice.FocusMode.continuousAutoFocus
completion()
} else {
device.focusMode = AVCaptureDevice.FocusMode.locked
var _lenspos = Float(context.config.basic_settings.lens_position) ?? 0.5
if _lenspos > 1.0 { _lenspos = 1.0 }
if _lenspos < 0.0 { _lenspos = 0.0 }
device.setFocusModeLocked(lensPosition: _lenspos, completionHandler: { (time) in
completion()
})
}
This code can successfully set focus mode to autofoucs or manual focus and also can set lens position perfectly if we use iPhone13 or iPhone14. But If we use iPhone15, this code cannot set the focus mode or lensposition. We also tried with different iPhone15 devices, but the result is always the same(fails to set focus). And also used different iPhone13 and iPhone14 devices. But these iPhones can set the focus correctly everytime. Is it a bug of iPhone15? Or is there anything that I can do about the issue?
