iOS 18
Last updated
Late on Friday, Apple uncharacteristically issued an update to its current developer beta four of both iOS 18 and iPadOS 18.
On Friday, Apple released an update to its fourth developer beta for iOS 18 and iPadOS 18. The build numbers on both were previously 22A5316j and now are 22A5316K.
Apple has not said what the update entails, so it’s likely a security or urgent bug fix that couldn’t wait for the next expected refresh.
AppleInsider and Apple strongly recommend that users avoid installing test operating systems or other beta or RC software on “mission-critical” or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they always have sufficient backups of their critical data.
