Apple typically locks down signing an iOS update for one or two weeks after its release. When an update is locked from signing, iPhone users will no longer be able to install it due to server-side software verification checks.

| Apple has stopped signing iOS 18.5, meaning iPhone users can no longer downgrade. |
And this time too, just about a week after releasing the iOS 18.6 update, Apple officially stopped signing iOS 18.5. This policy aims to encourage iPhone users to upgrade to the new operating system, ensuring security improvements.
iOS 18.6 is a minor update focused on fixing bugs related to Photos that could prevent users from sharing memorable videos. Additionally, this new iOS version patches over 20 security vulnerabilities.
Experts also recommend that iPhone users update to iOS 18.6 as soon as possible, especially if they are using earlier versions of iOS 18 which have many security vulnerabilities.
Therefore, once iPhone users have upgraded to the latest iOS 18.6 version, they will no longer be able to downgrade to iOS 18.5.
