Summary Abstract Swift and C++ handleMessage differences

Reported 2025-12-15 08:21:58 PST
We recently introduced the ability for the IPC handleMessage code to call directly into Swift message handling functions, via Swift/C++ interop. This led to the various 'handleMessage' functions becoming full of highly nested 'if' clauses, due to the different behavior for Swift and C++. We should extract these differences into the (pre-existing) MethodSignatureValidation structure, such that the 'handleMessage' functions themselves can regain their former simplicity.
