Abstract

When an instance is no longer need, Swift deallocates the instance and frees up the instance resources. For the most part, this is an automatic process that you don’t need to worry about when you are using standard Swift types. However, if you are using resources that need to be manually freed up (such as open files), you can de-initialize these resources by overriding the deinit method (see Listing 42-1).
