How can I correctly scale a UIImage from 3264x2448 down to 640x480 pixels?
I have an iOS app that interacts with a macOS server process. The iOS app takes
a 3264x2448 camera image, scales it to 640x480 pixels, and makes a JPEG
representation of it to send to the server:

In my MacOS app I need to display some vertical text (normal text rotated 90

I don't see anything in NSTextField or Xcode IB that allows a change of
orientation. Could NSAttributedString be used to do this, or is there some
CoreGraphics way?

iOS 10.3.2
I'd like to do monochrome (or single channel red) video recording, but it seems
iOS does not support this.
According to AVCaptureVideoDataOutput -availableVideoCVPixelFormatTypes, the
only supported pixel format types available for the iPad Pro in iOS 10.3.2 are:
'420v' - kCVPix

iOS 10.3.2
Using AVFoundation, I've set up an AVCaptureSession, and added an
AVCaptureMovieFileOutput to it. This stores the recorded video in the sandbox
as a movie file.
Is it possible to add encryption to this chain, so the movie file is written
out encrypted?

You are right. Without anything to go on, it's a hopeless task. I really need
to bump this back and try to get a hold of somebody

I have megabytes of raw legacy science datasets that I'm trying to read into my
app and ingest into an array of doubles. The data is supposed to be organized
as a stream of 8-byte doubles. I do not know how these datasets were generated,
so I don't know what format (big/little endian, byte swapp

iOS 10.2.1
I'm using UIAlertController -addTextFieldWithConfigurationHandler: to display
an alert with a textfield.
Is there any way to shorten the width of the displayed textfield? I've tried
setting its frame/bounds, but it has no effect.
