Rare crash with password generator keyboard

[xuaninbox]

In Jun last year i did a pr to add support for the iOS12 password generator keyboard:

but due to this issue:

We have seen crashes happening on the FUIPasswordSignUpViewController, maybe this feature should be removed for now until apple fix it?

The linked stackoverflow question mentions the Firebase/Performance as being a contributor to the crash. Are you using Performance, or does the crash reproduce without it?

[xuaninbox]

Yes we do use Performance but we haven't seen this crash before adding the auto password generator, maybe they are related?

[morganchen12]

Seems related to this issue: firebase/firebase-ios-sdk#2283

We can disable the password autofill, but I'd also like to leave it available for users who aren't using Firebase Performance.

This should be reverted once firebase/firebase-ios-sdk#2283 has been released.

@xuaninbox Seems the pr above is discarded. Do you want to revert it again?
