Apple releases first iOS 26.3 developer beta for iPhone

Apple has rolled out the first iOS 26.3 developer beta for iPhone, kicking off the next round of testing. One expected change is an Apple-Google initiative designed to make switching between iOS and Android easier.

This beta follows last week’s public release of iOS 26.2, which introduced deeper ways to tweak Liquid Glass design elements, added more CarPlay customization options, and delivered other refinements.
