Apple want to build exactly that. The trouble is the EU rejected apples proposal.
Apple did not simply withdraw from the EU market. Over the months before WWDC, the company put forward multiple technical architectures intended to resolve the interoperability problem without, in its view, turning every iPhone into an open-access system for any AI provider.
The most developed was a framework called the Trusted System Agent — a software intermediary that would broker third-party assistants' access to the same iPhone capabilities Siri AI uses. Instead of giving rival AI systems a direct connection to messages, files, and app controls, the Trusted System Agent would have acted as a gatekeeper, mediating access, enforcing user consent flows, and limiting what any single assistant could do autonomously. Apple also proposed a phased rollout: launch Siri AI for EU users immediately, then gradually deploy the Trusted System Agent over 18 months so competing assistants could reach the same capability level safely.
The European Commission rejected both proposals. According to Apple, the Commission did not accept any of the solutions put forward over several months and did not offer alternatives. Apple's statement characterized the Commission's position as requiring that any AI system receive "nearly unlimited access" to a user's device — including the ability to read and send messages, make purchases, access files, and execute actions across any installed app, without requiring ongoing user consent or visibility. The Commission has not issued a public statement in direct response to the WWDC announcement as of June 9, 2026, and a spokesperson did not respond to requests for comment outside business hours on June 8.
