Failed to open file at path '/default.realm.lock': Operation not permitted

### What happened? I expected to be able to have realm load inside an app or AUv3 plugin running on iOS. I got an exception with the message: "Failed to open file at path '/default.realm.lock': Operation not permitted" I would expect the lock file to be saved in the same location as the database path. ### Repro steps Build an application with Realm 2.2.0, that tries to open a local realm.
