code 16, Apple's app development tool for iPhone, iPad, and Mac software, includes a built-in AI feature that suggests code as developers type. It can complete a single line, fill in function arguments, or generate an entire function body based on a comment. The feature launched in September 2024 and runs entirely on the developer's own Apple Silicon Mac, keeping code private and working even offline.
Details
The predictive code completion feature uses a machine learning model trained specifically on Swift programming code and Apple's software development frameworks. The model is roughly 2GB in size and requires macOS Sequoia, Apple Silicon hardware, and at least 8GB of memory to operate. Unlike competitors such as GitHub Copilot (which sends code to cloud servers), Apple's tool processes everything locally. Apple separately announced Swift Assist, a chat-based coding assistant that runs in the cloud using Private Cloud Compute, but as of early 2026 Swift Assist had not shipped publicly. Xcode 16 also supports third-party large language models such as Claude and GPT-4 via plug-in integrations.

OtherSafari's Intelligent Tracking Prevention (ITP) uses machine learning running directly in the browser to identify advertising networks and data companies that track users across different websites, and then blocks or limits their ability to do so. First introduced in September 2017, ITP has been updated continuously and now blocks third-party tracking cookies entirely by default.Creative GenPersonal Voice is an accessibility feature introduced with iOS 17 in September 2023 that lets users create a synthetic voice that sounds like their own. It is designed primarily for people who are at risk of losing their ability to speak due to conditions like ALS. After recording 150 short phrases (roughly 15 minutes of audio), the device processes the recordings overnight using on-device machine learning and creates a voice clone the user can speak through in calls, FaceTime, and apps.OtherApple Watch uses machine learning algorithms to detect when a wearer has had a hard fall or been in a car crash, and can automatically contact emergency services if the person is unresponsive. Fall Detection has been available since Apple Watch Series 4 in 2018. Crash Detection for severe car accidents was added with the iPhone 14 and Apple Watch Series 8 in 2022.
