Are there reserved keywords for destructors in Swift? Is there even a need for such a thing in this language?

Destructors in C# are methods inside the class used to destroy instances of that class when they are no longer needed. The Destructor is called implicitly by the.NET Framework’s Garbage collector and therefore programmer has no control as when to invoke the destructor.
An instance variable or an object is eligible for destruction when it is no longer reachable. A Destructor is unique to its class i.e. there cannot be more than one destructor in a class.

A Destructor has no return type and has exactly the same name as the class name (Including the same case). It is distinguished apart from a constructor because of the Tilde symbol (~) prefixed to its name. A Destructor does not accept any parameters and modifiers.

deinit (Deinitialization) handles cleanup which should occur before the object is released.

There are a few standard things done in deinit. Remove observers, synchronize the state of an object, and write trace messages for debugging. Other things are possible, just avoid long running chunks of code.
