Courses Plus Student 9,332 PointsFirst you need to understand the definition of a struct. With a struct you can create a data type like the primitive type: Strings, Numbers, you named it. That's why he said he wants to return an array of type Points, because he created a data type of type Point. But first you need to understand the definition of structure.

3,134 Pointswell an array can have any kind of objects inside it, we are used to have array with objects of type Int for example, the syntax is something like this:
var numberArray : [Int]this way we are making the numberArray array with objects of type Int inside it. now as mentioned we can make structs Point like we made in the video. Now we can make an array with objects of type Point like this:var PointArray : [Point]the array PointArray have objects of type Point (Point is a structure). Hope my answer made sense. :)
