I have PR #1020 ready with a fix. Sorry for the inconvenience.

@nielsenko
Did you have approximate update date for fix this?
I'm big fan of back link feature and I want to test it asap.

Hi @barqui
We are awaiting an important fix for iOS from realm-core before cutting a release. I'm told it should happen today.
