Beyond code generation
During the WWDC 2026 keynote, Craig Federighi outlined new capabilities of Xcode 27's coding assistant. Beyond full app simulation already announced, the assistant can now automatically localize an application — handling strings, translations, and regional adaptations — and interact with simulated devices to test scenarios autonomously. These features bring agentic development into areas that were previously entirely manual.
Custom skills: taking AI beyond the device
The second relevant addition concerns custom skills: developers can extend the coding assistant's capabilities with specialized skills running on servers. As Federighi described in the MacRumors live blog, the ecosystem opens up to hybrid logic where part of the reasoning happens on-device and part in the cloud via the Foundation Models framework. This pattern likely previews a development cycle that will become dominant through 2026-2027.
