How in Swift to know that struct is deleted from Memory?
Structs are deallocated when they go out of scope. You can't put a deinit in a struct, but here is a workaround. You can make a struct that has a reference to a class that prints something when deallocated.
class DeallocPrinter { deinit { print("deallocated") }}struct SomeStruct { let printer = DeallocPrinter()}
So when the struct is deallocated - if you haven't made a copy of the struct, it'll print deallocated when it's deallocated, since the DeallocPrinter will be deallocated at the same time the struct is deallocated.
A simple way is the using of a dummy class. Just create an empty class and implement there the deinit(). Then use this class in your struct as member, p.e.
let dummyClass = DummyClass()
Once the structure is released, the deinit() function of the class is called. If not, then you have a memory leak.
