How to search an Array containing struct elements in Swift?

问题

It's kind pretty straight forward to find an element in an array with type String, Int, etc.

var States = ["CA", "FL", "MI"]
var filteredStates = States.filter {$0 == "FL"} // returns false, true, false

Now, I created a struct

struct Candy{
    let name:String
}

and then initialized it

var candies =  [Candy(name: "Chocolate"),
Candy(name: "Lollipop"),
Candy(name: "Caramel")]

Can anyone please suggest the right way to find "Chocolate" in the array containing struct elements? I'm not able to implement the find or filter method.

回答1:

With the following code you receive all candy structs in the array, which match to "Chocolate".

var candiesFiltered = candies.filter{$0.name == "Chocolate"}

If you just want a boolean if it has been found or not you could use the following code:

var found = candies.filter{$0.name == "Chocolate"}.count > 0
