I've set up an iPhone using Apple Configurator and enrolled it in MDM with a passcode policy that allows up to 10 failed attempts before wiping the device. This worked fine on iOS 17, but I'm noticing that on iOS 18, the device isn't wiping after those failed attempts. I've checked that the device is supervised, the policy is active, and even the MDM-enforced payloads aren't triggering a wipe. Has anyone else experienced this issue? Did Apple change something in iOS 18 that affects this feature? I'm wondering if this is a bug or if there's a new hidden setting or requirement.

We encountered a device on iOS 18.4 that wiped after failed attempts, but I’m not sure about the latest update (18.5). There seems to be some inconsistency here.
I haven't tested this on iOS 18 yet, but I did see it work fine on iOS 17 when setting up Intune. It's strange to hear it’s not functioning like before. Maybe there’s a bug?
There's usually an option to toggle the wiping after a certain number of attempts. I’ve seen it there for a while now, so check if that’s still available.
Have you checked if the 'erase data' option is enabled? In iOS 18, it includes the setting to wipe after 10 failed attempts by default, so you might not need to set that up separately.
Yeah, worked well on iOS 17 for me too. Reporting this to Apple could be tricky, and who knows how long it takes for them to respond.
