Apple Begins Testing iOS 18.6 Update for iPhones
Apple this week began testing iOS 18.6, according to our website's visitor logs, which have been a reliable indicator of upcoming iOS versions. The update is currently limited to Apple's software engineers, with no developer or public beta available yet.

The first iOS 18.6 beta will likely be made available in May or June, and the update should be released to the general public before the end of July.
It is still too early to know what new features and changes will be introduced in iOS 18.6, if any. iOS 17.6 and iOS 16.6 had only bug fixes and security patches, but earlier updates like iOS 13.6, iOS 14.6, and iOS 15.6 included some new features.
Apple recently delayed personalized Siri features until some point "in the coming year," but the current consensus is that those upgrades will not launch until the iOS 19 cycle.
The chart below recaps "point-six" updates over the past five years.
