nkhvorov Will I be able to freely access from Unity any directory (described in this AIR docs) in iOS?
No. iOS is by far the worst in this respect (or the best, from the point of view of user security). Apps simply can’t access each other’s data. There are ways for apps to communicate and share data but they are opt-in and limited to particular use cases and data types.
The only way is if both AIR and Unity versions of your app access the same private directory. From the above link the Unity API uses a sensible path
But it’s unclear if AIR uses the same path – the documentation gives
/var/mobile/Applications/<uid>/Library/Application Support/<applicationID>/Local Store but it’s very old and does not seem to conform to current iOS practices. I suspect Adobe may have changed it, but not documented it.
