At WWDC 2025, Apple unveiled its new Foundation Models framework, a significant step forward in empowering developers to use its AI models in a completely offline, on-device manner. Craig Federighi, Apple’s VP of software engineering, took the stage to introduce this feature, highlighting how it will allow developers to integrate Apple’s on-device AI models into their apps without relying on cloud API costs.
One of the key features of this framework is its ability to support offline AI experiences, which is especially important for applications that need to function in areas with limited or no internet access. For example, apps like Kahoot could create personalised quizzes using on-device models, enhancing the studying experience for users. The benefit of these on-device capabilities is that they operate without the need for cloud connectivity, making the process faster, more secure, and more private.
The Foundation Models framework is built to be easy for developers to use, with native support for Swift, Apple’s programming language. According to Apple, developers can integrate these powerful AI models into their apps with just a few lines of code. This simplicity makes it easier for even smaller developers to incorporate sophisticated AI into their applications.
Already, some well-known apps are tapping into the framework. Automattic’s Day One journaling app is using the Foundation Models framework to create engaging user experiences, while the popular mapping app AllTrails is leveraging it to recommend personalised hiking routes. Apple has made the framework available for testing through the Apple Developer Program, with a public beta set to launch next month.
Overall, Apple’s Foundation Models framework offers an exciting new opportunity for developers to bring AI-powered features to their apps, all while maintaining user privacy and enabling offline capabilities. It’s another step in Apple’s ongoing efforts to make AI more accessible and usable on its devices, without compromising on performance or security.
