I have cloned this repo:

https://github.com/austintt/CoreMLVision

I have a variant of the VGG16 model called cats-dogs-VGG16.mlmodel added which has two outputs. It has been converted from a Tensorflow model to CoreML using Apple's CoreMLTools: https://github.com/apple/coremltools

The makePredictions code the code in ViewController.swift is changed to look like this:

    func makePredictions(image: UIImage) {

        do {

//            let model = try VNCoreMLModel(for: Inceptionv3().model)

            let model = try VNCoreMLModel(for: cats_dogs_VGG16_1().model)

            let request = VNCoreMLRequest(model: model, completionHandler: displayPredictions)

            let handler = VNImageRequestHandler(cgImage: image.cgImage!)

            try handler.perform([request])

        } catch {



        }

    }

Of course, when the first let model = line is the one executing, everything is fine. This is the intended functionality.

When the code is as above, with a debug stop point on every line, the execution gets as far as the let model = line and then stops with this message:

Why is the query cancelled?
