Apple has updated and re-released the sixth beta version of iOS 26 for developers. This new build, which comes just a few days after the first beta 6 released on Monday, carries the same version name but a different build number. Initially released to developers on Monday with build number 23A5318c, it was re-released today with build number 23A5318f.

iOS 26 beta 6 released

The fact that the new build’s version name hasn’t changed indicates that Apple hasn’t added any significant new features to the system or made any major changes that directly impact the user experience.

The update is believed to be designed to address some bugs or security vulnerabilities identified before the public beta was released. This new developer build, released simultaneously with the public iOS 26 beta 3, indicates that Apple has taken swift action to address some critical issues during the development process.

The first build of iOS 26 beta 6 released on Monday provided a smooth performance experience for some users. However, the release of this updated build demonstrates that the technical issues some users have encountered or the security vulnerabilities discovered behind the scenes have not been ignored. Apple did not provide any details in the release notes or provide any information about the scope of the changes.

Developers are required to install the updated version with this new build number on their devices. While Apple has not disclosed details of potential issues with the previous build, it is believed that this version may contain significant security and stability changes. The updated beta 6 is an interim intervention to ensure the overall stability of iOS 26.
