How to use Leaf in iOS app in 2025?

[tstavnychyy-scudio]

Hi Everyone.
I recently started developing VPN client using Leaf library on iOS and curious how are you using Leaf in your iOS projects? Because it seems that non-official method to get TUN File Descriptor id has stopped working, and now iOS app should only use packetFlow and redirect data to Leaf. Has anyone made some progress here or can share some insights? Thank you.
