Help me Initialize All the Things !

I need help understanding initializing because I'm not exactly sure of what I'm doing nor do I possess the technical acumen of when I should be using them. I have a VERY light idea of when I should be using them. I'm not even sure what or why it exist. I just know I need them. Convince initializers are also confusing.

Are initializers put in place to give default values for your classes as a starting point ?

I went on ahead and re-watched some of Amit's videos and re-wrote the code. My questions are asked inline 

 // These are the initial values, correct ? Are these the starting points for an object ?
class Product {
    let title: String
    var price: Double = 0.0


   // 1st initializer - Does this set a default value of title and price to "title" and "price" ?

   // This doesn't make sence to me because price should be a double, right ?

   // If we have this, why do we need to declare initial values above ? @ starting points

 // code like this seems redundant to me. I feel like we are saying 
//"This particular classe's title and price are equal to title and price"
// Can anyone  elaborate on this for me ?

    init (title: String, price: Double){        
        self.title = title
        self.price = price
    }
