Rapid enhancements in Artificial Intelligence over the past few years have revolutionized the workflow in different sectors. Integration of AI with software development tools can enhance the efficiency and productivity of developers. Tools such as GitHub Copilot, Cursor AI, etc, provide AI assistance to automate repetitive tasks, and Apple has also lagged behind in the race, introducing AI features in its Integrated Development environment- Xcode.
In this article, we will discuss the AI features of this app and how you can make the most out of them.
What is Xcode AI Assistant?
The AI features of Xcode, available on Xcode for Windows and Mac, include “Predictive Code Completion” and “Swift Assist.” These tools assist developers in bug detection, suggesting and auto-completing code, etc, and increase their efficiency, also speeding up the development process that comes under AI Assistants and making Xcode one of the best IDEs.
How to Use Xcode AI Assistant?
AI features of Xcode.
- Predictive Code Completion.
- Swift Assist.
Predictive Code Completion
Predictive Code Completion is a new AI feature of Xcode 16. It helps you write code faster by suggesting it. It is trained for Swift and Apple SDKs (Software Development Kits) by Apple. Predictive Code Completion runs locally on your Mac, which means your code is kept completely private and not used for any training purposes by Apple. And you can use it even while working offline.
Requirements For Using Predictive Code Completion
- You must have Xcode 16 or a later version of it.
- Must have a Mac with Apple silicon and macOS 15 or later.
- More than 2 GB of free disk space.
- 16 GB RAM.
How to Install Predictive Code Completion in Xcode?
To install Predictive Code Completion on your Xcode, follow the given steps.
Installing Predictive Code Completion on Xcode 15 and older versions-
- Update your Xcode app from the Mac App Store and make sure you’re using Xcode 16 or later.
- After updating, when you open Xcode, a window will pop up on your screen. Here, you can do a check on “Predictive Code Completion Model” and click on “Download & Install.”
- Now enter your password and click on “Install Software.”
- Then it will load for some more time, and a window will pop up on your screen, where you click on “Relaunch Xcode.”
- After relaunching the Xcode application, the download will start.
Installing Predictive Code Completion while using Xcode 16 or a later version-
- Open Xcode on your Mac.
- Go to Xcode (top left corner) > Settings.
- Click on “Text Editing” in Settings.
- Open the “Editing” section in Text Editing.
- Check the “Predictive code completion” option in the Editing section.
- Click on the “Download” button.
- Now “Predictive Code Completion” has been downloaded to your Xcode successfully.
- If you want to disable the Predictive Code Completion, then follow the same process and uncheck the “Predictive code completion” option in – Xcode > Settings > Text Editing > Editing.
How to Use Predictive Code Completion?
After downloading the Predictive Code Completion, to use it, you have to write the code in your code editor, and it will give you suggestions, and you can press the “Tab” key to accept these suggestions (see the GIF below).
You can also use comments to guide these suggestions. For example, when you write a comment, Predictive Code Completion will give you suggestions according to your comment, as you can see in the GIF below.
Predictive Code Completion gives decent suggestions, but it is not 100% accurate. Sometimes it makes mistakes while giving suggestions, and then you can edit them as per your needs. It suggests changes based on the context of your code, and as your project moves ahead, it becomes more accurate because now it has more context.
Swift Assist
It is the upcoming feature of the app and was announced by Apple at WWDC 2024 (Worldwide Developer Conference) 2024. Swift Assist is an AI companion for developers that helps them by seamlessly integrating with Xcode and knows the latest Software Development Kits (SDKs) and Swift language features needed for working with new frameworks.
You will be able to give prompts to Swift Assist and generate the code, which can be helpful for experimenting with new ideas. Swift Assist uses a model that runs in the cloud, so, unlike Predictive Code Completion, it requires an internet connection to use it. All your code data is used to process the request only and is never stored or used by Apple to train their AI & ML models.
In this article, we discussed the AI functionalities of Xcode that you can use to enhance your productivity. Note- these features are in their initial phase, and they are not 100% accurate, but with time, they will get better.
