Apple is aiming to launch the upgraded Siri that it originally previewed at WWDC 2024 in spring 2026 with iOS 26.4, according to Bloomberg. But in March, Apple delayed these features, saying in a statement that “it’s going to take us longer than we thought” to deliver them. If past trends continue, it’s possible that iOS 26.4 could arrive in March: iOS 18.4 launched on March 31st, while iOS 17.4 was released on March 5th. Apple originally planned to release the upgraded Siri in the fall alongside the iPhone 16 lineup, Bloomberg says. In reality, Apple’s initial Apple Intelligence features – which, for Siri, only included a new design – didn’t launch until more than a month after those phones came out.
