Apple has released new RC (release candidate) betas for its upcoming software updates, including iOS 18.6, to developers and public beta testers. The RC indication suggests that the launch of these operating systems is imminent.
iOS 18.6 will be accompanied by companion updates for iPadOS, macOS, tvOS, watchOS, HomePod, and visionOS (for developers only). Apple has been preparing these software updates in preparation for its major new OS versions launching this fall.
The accelerated release cycle, with RC betas arriving just one week after beta 3, suggests a public launch is likely to happen soon. However, the features introduced in iOS 18.6 are minimal, with the focus on stability and performance improvements rather than significant new enhancements.
Apple has also announced several EU-related changes coming to third-party app marketplaces and app downloads. These updates are expected to be released later this week or at the latest by next Monday, July 28.
With major OS updates like iOS 26 on the horizon, it’s likely that Apple is prioritizing stability and performance improvements in its upcoming software releases.
