it only works with the firebase JS SDK, not with AngularFire :(

@roldyclark Thanks for writing about this issue and sharing the solution. I am facing the same issue, however the proposed solution did not work. Only once I used the browserLocalPersistence persistence strategy, the initialization worked as expected on iOS. Do you have any idea why this could be or how to get the default indexedDB persistence to work?
