Overview
We discovered several issues when relying on manually created proxies using
NSObject
and overriding certain methods, such asresponds(to:)
andforwardingTarget(for:)
. While most of these issues can be (and were) resolved, we encountered problems with optional protocols being called from Swift, which could lead to unexpected behavior.Based on this and other internal discussions, we decided to move forward with a proper proxy by inheriting from
NSProxy
, allowing us to fully control the messaging chain.
