We’re looking into whether an iOS version is feasible.
A typical iOS messaging app would use a push notification to wake the app when a message is received, but this exposes metadata to Apple’s push notification service and the app developer’s push gateway
If we don’t use push notifications then the best Apple allows us to do is wake up every 15 minutes and check for messages. But maybe the sender won’t be online when we check (their 15 minute intervals might not be aligned with ours - clocks aren’t perfect).

As I understand it, these kind of applications depend on being able to perform activities in the background, which is highly limited in iOS for battery efficiency reasons–and maybe for privacy.
Many years ago I was working on a project that shared connectivity details over wifi/bt, and iOS was troublesome also due to the application not being aware of the local bluetooth address.
Possibly similar issues impact other mesh networking applications on the platform.
