So, let’s go with the trendy tech of machine learning because it is getting quite popular in the market.

A graphical representation from Grand View Research shows the global market size of machine learning was valued at $36.73 billion in 2022. They have also looked at how this industry will just grow year by year with an annual rate of 34.8% from 2023 to 2030.

Out of all the largest market size will be the United States with a value of $21.14 billion in 2024. (Source: Statista)

As USA users have a larger number of iOS users, integrating Machine Learning into iOS apps can transform user experiences, making them smarter, faster, and more personalized. Apple’s CoreML framework simplifies this process.

CoreML allows developers to seamlessly incorporate pre-trained machine-learning models into their iOS apps. Whether you are looking to enhance security, improve search functionality, or predict user behavior, CoreML has got you covered.

In this blog, you will learn about the whole process of integrating machine learning in iOS. It will help you understand how you can optimize performance and ensure data privacy.

Let’s dive in and see what exactly CoreML is and its process to integrate into your iOS app development.

What is CoreML?

CoreML does not allow you to create and train machine learning models directly on an iPhone. Instead, it’s a framework that lets you import pre-trained models into your app easily. You just drag and drop the models into your project, they are optimized to be fast, secure, and power-efficient. Essentially, you are using a pre-made “black box” that you can send data into and get predictions out of.

One of the best things about CodeML is that Xcode handles most of the setup for you when you import a model. It automatically generates Swift classes, making it easy to use your model in your code with a simple line like: ‘let model = sentiment_model ()’. We’ll look at a detailed example later, but basically, Xcode gives you a ready-to-use programmatic interface for your pre-trained model.

However, there is a catch, the interface’s quality depends on how well the model is defined. When a CoreML model is created, Xcode generates metadata describing its inputs, outputs, and functionality. If the model’s creator didn’t specify this metadata clearly, you’ll need to do some extra work to format the inputs correctly and understand how the model works internally.

Let’s go through this process in the next section.

Step By Step Process of Integrating CodeML into Your App

Step 1: Prepare Your CoreML Model

Before you start with Xcode, make sure your CoreML model (lstm_model.mlb package file) is ready.

Step 2: Create a New Xcode Project

In this step, use Xcode 15.1 to create a simple iOS and incorporate the CoreML model. Follow these steps to create your basic app:

1. Open Xcode and Create a New Project:
2. Open Xcode and select the option to create a new project.
3. Choose the template for an iOS app.
4. Set up your project:
5. Give your project a name and an organization identifier. You can choose any name you like or follow the example given.
6. Make sure to set the interface to SwiftUI and the language to Swift.
7. Open your project:
8. After creating your project, open the newly created .xcodeproj file. You should see a folder structure similar to this.

Step 3: Integrate CoreML with Swift

Import CoreML: In your ViewController or wherever you plan to use the model, import the CoreML framework.

import CoreML

Load the Model: Create an instance of the model class.

let model = YourModelName(data: yourInputData)

Prepare the Input: Ensure your input data matches the model’s required input format. This might involve preprocessing steps such as resizing images, normalizing data, etc.

let input = YourModelNameInput(data: yourInputData)

Make Predictions: Use the model to make predictions.do {

do {

 let prediction = try model.prediction(input: input)

   // Use the prediction result

} catch {

    print("Error making prediction: \(error)")

}Step 4: Handle Post-Processing

Process the Output: Depending on your model, you may need to post-process the output to make it usable for your application. This might involve deciding results, applying thresholds, etc.

Step 5: Optimize for Performance

Model Optimization: Ensure your mobile is optimized for on-device performance. Use techniques like quantization or model pruning if necessary.

Use Background Threads: Perform model predictions on a background thread to avoid blocking the main thread and keep your mobile design UI responsive.

Step 6: Test Your Integration

Test Extensively: Run extensive tests on various devices to ensure the model performs well across different scenarios and device capabilities.

Monitor Performance: Use Instruments and other profiling tools to monitor memory and CPU usage, ensuring the model’s inference does not degrade app performance.

Step 7: Update and Maintain

Regular Updates: Keep your model updated as you gather more data or improve the model’s accuracy.

User Feedback: Incorporate user feedback to continuously improve the model and its integration within the app.
