Apple is preparing iOS 26.6.1 and iOS 18.7.10 as two late-cycle iPhone updates focused mainly on security and reliability, with release candidate builds already appearing ahead of the expected public rollout. Apple’s public security page still lists iOS 26.6 as the latest general release, which arrived on July 27.
Apple distributed the iOS 26.6.1 release candidate with build number 23G82, while iOS 18.7.10 carries build number 22H373. The RC stage normally means Apple has finished major development unless testers discover another problem before release.

| Update | Build | Main focus |
|---|---|---|
| iOS 26.6.1 | 23G82 | Security fixes and bug fixes |
| iOS 18.7.10 | 22H373 | Security and stability updates |
Apple has not announced major new features for either update, and iOS 26.6.1 release information points specifically toward security fixes rather than interface changes or new apps.
Users can therefore expect improvements in areas such as:
- Security vulnerabilities discovered after iOS 26.6
- System stability and reliability
- Background software bugs
- Compatibility problems affecting apps or Apple services
- Smaller fixes Apple wants deployed before iOS 27 arrives
Why Apple is still updating iOS 18
iOS 18.7.10 remains important for older supported hardware and users staying on the previous operating system. Apple previously released iOS 18.7.9 in May, while the newer 18.7.10 build is numbered 22H373.
Meanwhile, iOS 26.6 already included security fixes and changes to the Spotlight index that prepare devices for iOS 27, so iOS 26.6.1 appears to be another maintenance release before Apple shifts its attention toward the next major version.
With release candidate builds now available, iOS 26.6.1 and the corresponding iOS 18 update are in the final stage of testing, making a wider public rollout the next expected step.
