iOS12.0 Safari Autofill Bug
Hopefully this will save some of the Community some unnecessary angst - should they come across this bug in iOS12...
There appears to be a significant bug with Safari’s Password Autofill function on the iPad, such that after updating the iPad to iOS12, from 11.4.1, Password Autofill stops working. No amount of Googling has found a corresponding complaint at this time - and this Community doesn’t appear (yet) to have described the specific issue that I’ve encountered - initially with an iPad Mini 2 (A1490). It may affect other variants (as yet unconfirmed), but due to the seriousness of the bug for me, I’m not about to make the mistake of upgrading my iPad Pro to iOS12 so as to prove the point!
After many days of systematic debug (and support calls with the Apple Support Team - without finding resolution) - I have found the apparent cause of the problem - and since demonstrated its consistency with my configuration.
The problem is this:
When attempting to access a website that requires login, Password Autofill is not offering to populate the appropriate fields with credentials from the keychain. When you are routinely using strong/complex passwords, that are different for every account, this problem becomes serious when you rely upon the iOS keychain for credential management.
The bug, that prevents Autofill from working, is with split-keyboard (which I routinely use without thinking about). If you use the full-screen keyboard, that occupies half your screen, then Autofill in iOS12 works broadly as intended; the keyboard directly offers credentials when it senses a logon page. With split-keyboard, the keyboard does not offer credentials; whether this is a failure to “sense” the input fields - or a failure to offer credentials - I cannot say.
So, if you are unlucky enough to experience an Autofill issue in iOS12 - and you are using the split keyboard feature - the workaround may be to return to using the full keyboard. Hopefully Apple will fix this.
If you experience this problem, I strongly recommend that you fill-in Apple’s feedback form to report the issue and/or contact Technical Support. Any responses here will also be useful to Community members.
