Why are initializers used?

I'm confused. Why do we need an initializer in our struct? Can someone give me a real life world example? Just a little confused.

As the video showed. Your struct have an initializer by default. However, that initializer requires you to specify all the values. If you want to avoid that behaviour you need to specify your own init function. When you do that, the default init is overridden and your function will be used instead. On that function you can ask for specific values.

Structs are similar to objects.

The parameters to init( param1: value, param2: value) can be passed through so you can pass through multiple values to the stored property of your struct. it is interesting, that you can do this easily with enums with this new swift protocol.
