This is a well-known library interoperability dynamic, and IMO we can't expect the solution for conflicting libraries to be that you have to get the library authors to communicate with one another. That effectively fixes nothing for the poor app developer who integrates these libraries. -- -Dave _______________________________________________ swift-evolution mailing list [email protected] https://lists.swift.org/mailman/listinfo/swift-evolution
