According to 9to5Mac, iOS 26.2 beta 3 code reveals Apple is preparing to let users replace Siri with third-party AI assistants when using the iPhone’s side button. The update includes a new ‘SystemVoiceAssistant’ system app and references to a ‘Side Button App’ that would handle the assistant switching. iOS 26.2 will launch next month as Apple’s final major software update before the holidays. The timing suggests this is likely Apple’s last chance to implement Digital Markets Act compliance measures with end-of-year deadlines. Although unconfirmed, the feature appears highly likely to be limited to the European Union where DMA regulations require such interoperability.
The Siri Replacement Reality
This is honestly huge. For years, iPhone users have been stuck with Siri whether they wanted it or not. The side button has been Siri’s exclusive territory since… well, forever. Now Apple might finally be opening that up. But here’s the thing – this isn’t about Apple suddenly becoming generous. This is pure regulatory pressure from the EU’s Digital Markets Act. They’re basically being forced to play nice with competitors.
What This Means For Users
Imagine being able to summon ChatGPT, Google Assistant, or Amazon Alexa just by pressing the side button. No more “Hey Siri” awkwardness. No more switching between apps. It would fundamentally change how people interact with AI on their iPhones. But let’s be real – how many people will actually switch? Siri might not be perfect, but it’s deeply integrated into Apple’s ecosystem. Still, having the choice is everything. Competition could push Apple to finally make Siri… you know, actually good.
The EU Factor
This is almost certainly going to be another EU-exclusive feature, just like sideloading and alternative browser engines. Apple’s playing the “we’ll only do this where we’re forced to” game. Which makes sense from their perspective – why voluntarily weaken your ecosystem control? But it creates this weird situation where iPhone users in different regions have completely different experiences. Will people in the US and Asia ever get these features? Probably not unless their governments step up with similar regulations.
Developer Opportunities
For AI companies, this is massive. Getting system-level access to iPhone users? That’s the holy grail. But I’m curious how Apple will implement this. Will they create some kind of certification process? Will there be technical limitations? And what about privacy – will third-party assistants have the same level of on-device processing that Siri enjoys? There are so many unanswered questions.

The Bigger Picture
This feels like part of a larger shift at Apple. They’re being pushed toward openness whether they like it or not. Between this, the App Store changes, and RCS messaging, the walls are slowly coming down. Is this good for users? Absolutely. But it’s also risky for Apple’s carefully controlled experience. The question is whether they can maintain their famous “it just works” philosophy while letting third parties into their most sacred spaces. Next month’s iOS 26.2 release can’t come soon enough.
