How can I fix the correct working model giving wrong result in app?

Question

I created an ML model using CreateML. This model classifies images as Cat, Dog, Rabbit. Selecting an image from the photoLibrary by clicking an imageView. It is processed by the selected visual model. The result is being printed to the Label. When I test the model using CreateML it works fine. But in the application, it gives the same wrong results for every image. After starting the app, no matter what image is selected, it gives these results in order each time:

• 77% Dog
• 83% Cat
• 71% Cat
• 56% Cat ...

Please help me. Thank you for interesting.

When the application is opened for the first time:

When selecting an image from the photoLibrary:

First result

Second result

Code :

        UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
        image.draw(in: rect)
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        
        return newImage
    }

}

I tried these :

• Do operations in different threads
• Resize selected Image
• Remake the model
• Edit PHPicker configurations
