iOS 26.6 adds new alert when you try blocking too many contacts

iOS 26.6 beta 1 arrived today, and with iOS 27 right around the corner, it’s unsurprisingly very light on changes. But one difference was discovered by Aaron Perris: a new alert that appears in iOS 26.6 when you try to block one contact too many.

iOS 26.6 code reveals new alert when you’ve maxed out your blocked contacts

Apple doesn’t publicize this information, but iOS quietly enforces a limit on how many contacts you can add to your ‘blocked’ list.

Though the vast majority of users likely never hit that limit, iOS 26.6 adds a new alert for the few that do.

Here’s what it says, per Aaron Perris:

Blocked Contacts Limit Reached
