Just discovered recently that keynote does have a collaboration function through iCloud. Was a little clunky to get going but is working great now. Not quite google docs but it does instantly sync across devices when you save

All the iWork apps have collaboration functionality (with mostly full feature parity), and it works on macOS/iOS/web too.

Disclosure: Was a QA Engineer at Apple on those apps/that functionality.

If you have two iOS iWork apps, can each one sign into a separate iCloud account? Or are all iWork apps forced to use a device-wide iCloud login?

[minimaxir]

Unfortunately no; it just uses the system login set in Settings.

Hopefully Apple will enable multiple identities for apps as part of their new push for single signon. They recently added multiple device users for schools. Enterprise users can have per-app VPNs.

Ironically, because Google and Microsoft collaboration apps don't have iOS platform control, they are much more flexible in supporting multiple user identities.

There are many scenarios where information needs to be separated (projects, consultants, cross-org teams, OSS projects) and multiple identities are a proven means of separation and compliance. This needs to be possible without Enterprise MDM.

I think each just pulls from the system account.

Just curious, what makes it "clunky" to you?

For my use, there's a "Collaborate" button. You click it and invite people. Once they click the invitation, you can watch them view/edit.
