SwiftyJSON.swift:267caused by a race condition when multiple threads access JSON dictionaries concurrently. Theunwrapfunction was mutating a dictionary while iterating over it withforEach, which caused a crash during Copy-on-Write when accessed from multiple threads. The fix creates a new dictionary instead of mutating during iteration.Checklist
