Summary

Libp2p relies on a package called [email protected] in 4 different places:

transport/tcp
transport/quic
transport/webrtc
protocol/mdns

This unmaintained library uses a deprecated iOS interface through one of its own dependencies `[email protected]:

https://discuss.libp2p.io/t/rust-libp2p-link-error-on-ios-undefined-symbols-kscnetworkinterfacetypeirda/2208

https://github.com/libp2p/rust-libp2p/issues/5140

Seeing that our bindings use this deprecated interface, iOS apps will fail to build for everyone using rust-libp2p.

Expected behavior

When adding the sdk.xcframework and the sdk.swift that we generate to be used inside the iOS app, the build works as there are no deprecated traits used

Actual behavior

When adding the sdk.xcframework and the sdk.swift that we generate to be used inside the iOS app, the build fails due to an undefined symbol _kSCNetworkInterfaceTypeIrDA

Relevant log output

No response

Possible Solution

The solution would be to update the system-configuration dependecy of the if-watch crate seeing if-watch is directly used in the libp2p repository
