Reproduce UIViewController deserialization with an empty dictionary from AppDelegate.swift:19, then inspect ContextDescriptorType.swift:83 and the callers in Metadata.swift and Properties.swift. Trace why fieldOffsets creates an invalid range for UIViewController; done means the reported deserialize(from: [:]) crash no longer occurs.
