Where to go next?
If you are interested into knowing more about Core ML, how to use machine learning models in your development projects or how to create custom models you can check our other articles:
Demo App Overview
The app we are trying to make is fairly simple. Our app lets user either take a picture of something or choose a photo from their photo library. Then, the machine learning algorithm will try to predict what the object is in the picture. The result may not be perfect, but you will get an idea how you can apply Core ML in your app.
Getting Started
To begin, first go to Xcode 9 and create a new project. Select the single-view application template for this project, and make sure the language is set to Swift.
Creating the User Interface
Editor’s note: If you do not want to build the UI from scratch, you can download the starter project and jump to the Core ML section directly.
Implementing the Camera and Photo Library Functions
Now that we have designed the UI, let’s move onto the implementation. We will implement both the library and camera buttons in this section. In ViewController.swift, first adopt the UINavigationControllerDelegate protocol that will be required by the UIImagePickerController class.
Integrating the Core ML Data Model
Now, let’s switch gears for a bit and integrate the Core ML Data Model into our app. As mentioned earlier, we need a pre-trained model to work with Core ML. You can build your own model, but for this demo, we will use the pre-trained model available on Apple’s developer website.
Converting the Images
In the extension of ViewController.swift, update the code like below. We implement the imagePickerController (_:didFinishPickingMediaWithInfo) method to process the selected image:
Using Core ML
Anyway, let’s shift the focus back to Core ML. We use the Inceptionv3 model to perform object recognition. With Core ML, to do that, all we need is just a few lines of code. Paste the following code snippet below the imageView.image = newImage line.
