Discover memory leaks with Testcase
summary
Describes an automated memory-leak detection technique for Swift using XCTest plus Mirror and weak-box wrappers: reflect an object’s stored properties, place any class instances into weak containers, and assert they become nil after the owning view controller is deallocated. Explains practical pitfalls such as casts through Any, Optional double-wrapping, and differences between structs and classes, and notes a limitation that Mirror itself can increase a reference count and produce false positives.
