I have an iframe in an Ionic 2 application. This iframe (different origin but I control both sides) uses indexedDB. I receive the error “IDBFactory.open() called in an invalid security context” when opening the database in the iframe on iOS. Note that it works on Android or on the web interface.

Is there anything I can do to make this work? I would like to avoid re-developing everything and just glue so that I can use my existing code in the iframe.
