Apple held its annual developer conference today, and as usual used the keynote address to announce all of the new software features coming to Apple's many products this fall. This year's WWDC is occurring at a moment of unprecedented economic uncertainty. Apple's sales are expected to take a hit as President Trump continues to threaten the company with increased trade tariffs. The event also comes in the aftermath of the very AI-heavy conference of Apple's archrival Google, putting pressure on Apple to show off what has so far been a delayed and underwhelming foray into consumer-facing artificial intelligence.

That means a pre-release version of the iOS 26 operating system for iPhones is now accessible for registered Apple developers to test.
