Apple rolled out iOS 11 developer beta 6 (build 15A5354b) on Monday as we get ever closer to the official release this fall. The update is available for developers with compatible iPhone, iPad, and iPod touch models.
iOS 11 developer betas require an Apple Developer account and an iPhone SE or newer, fourth generation iPad or newer, or a sixth generation iPod touch. The update is available through the iOS Software Update option, or through the Developer website if you haven’t signed up for beta testing yet.
Monday’s release represents an accelerated release cycle, as the last round of developer betas hit just one week ago. Apple is expected to ship macOS High Sierra in September or October.
This release does not affect those who are running the public beta of iOS 11.
