Just days after the original, a new build of iOS 18 beta four has been issued to developers by Apple. The build number for the new beta 4 is now at (22A5316K) and it supersedes the prior release that seeded last Friday as a part of dev.the evaluation. This fast revision is causing curiosity and raise as to what changes are being done or new features will be in this latest addition.
The Original Beta 4 Major Features Released initially on July 23, iOS beta 4, the first of its kind before it gets official as iOS18, includes a few new features and changes.

Fresh CarPlay Wallpapers: Apple released a new selection of wallpapers to decorate the in-car experience more with the arrival of additional customization opportunities for users. Modified Hidden Apps Folder: An important change in the UI which lets users easily manage and find their hidden apps. More RCS Carriers: Apple extended the Rich Communication Services (RCS) to additional carriers, delivering better messaging amenities. Dark Mode Icons On Light: You can use light mode, but enjoy dark icons for an aesthetic contrast. There are a lot of tweaks such as Interface Tweaks which include tons of small improvements targeted at refining the user experience both functionally and aesthetically.
Why Make the Update?
Apple never actually stated why it needed to push out the revised update, but speculation suggests that an unearthed vulnerability or a particularly nasty bug detected inside-both of which are highly likely given its need for such swift action. Beta is the testing ground of sorts, and it’s rare that Apple would not be sending out quick updates if necessary to solve any major issues early on with feedback from developers.
What might have been new in Beta 4 Revised It’s not clear exactly what has changed in the updated iOS 18 beta 4. But, developers should at least install this new build and submit a report if there are indeed any changes or improvements done. As per the beta nature of all releases, it is more probable that those issues are at play if developer this update includes:
Beta 4 Vulnerabilities Fixes:
Bugs and vulnerabilities in Discourse fixed within an hour of smart users poking holes. Performance improvements: Various parts of the game have been optimized to give a more stable and smoother performance. Additional Features: Chances are the beta 5 software will include new features or bug fixes that were initially planned for, but not implemented in the original beta 4 release.
Pattern of Updates This is in line with the past few weeks, where Apple has shipped a new build of developer beta 3 ahead of public betas for iOS 18. Using these directions, Apple can review the developer beta and make it as smooth an experience as possible before rolling it out to eager iPhones. This new developer beta 4 could signal the release of public beta 2, from what we heard on rumors a release next week (maybe Monday?).
A Developer Aspect in Updating a Process Apple has an extensive developer base that can beta test out these versions and provide feedback on any issues. Developers are part and parcel of:
Bug Identification: Providing details of any bugs or problems they come across to assist Apple in fixing them quickly. New Feature Testing: Validation of functionality and usability from a user perspective, ensuring the feature is serving users based on their requirements. Performance feedback: How fast, the beta build held stable or not and was the overall user experience.
Conclusion
Apple’s release of the update to iOS 18 beta 4 not only proves a new effort by Apple in perfecting and priming its newest iPad operating system for probable stability. We still don’t know why the change is made, and reason aside it appears Fire TV OS team seems to be on an active quest for solving non-issues. You can check it out by joining the iOS Beta Program (make sure “Get Betas” is toggled on) and contributing your feedback to help improve iOS 18!
While we remain on the edge of our seats for more info and a public beta release, it’s important to remember that developers are still leading Apple’s mobile OS dance. We’ll be covering iOS 18 and all of its changes, so keep your eye out for further coverage on the platform.
