I just filed a report in Feedback Assistant: FB9824065

One way you could accomplish this is to use something like UIGraphicsGetImageFromCurrentImageContext() and then to capture separately a frame from the live camera feed before compositing the two images together with, say, Core Graphics to form one image that reconstructs what a “real” screenshot would show. I’m not sure if there’s a more elegant way to do it, but this method should work; it just might require some complex calculations to put the camera frame in the right spot with any appropriate masking, depending on the complexity of your UI layout. I suspect that whatever code the system runs when the user presses the hardware buttons is not accessible to third-party developers.

I don’t think that there’s a way to convert a playground book into an app directly. You should probably create a new, empty playground app and then copy and paste your code into it.

You might have better luck in the Apple Support forums.

That’s an issue with a non-Apple product/service, so this forum probably isn’t the best place for your inquiry. However, I’m pretty sure that Google Sheets doesn’t support Google Apps Script on iPad.

You could try force-quitting the appstoreagent process in Activity Monitor to see if it resets the app-download cache.

You could try following Apple’s instructions for installing TensorFlow with Metal-powered GPU acceleration, even if you don’t need that acceleration.
