Swift 3 Object-Oriented Quiz True or False Question

This is one of the questions on the quiz at the end of the video collection. I got it wrong and I'd like to know why I missed it.

When creating objects we can only use primitive types (like String, Int, etc) as the types for stored properties True or False

I answered True and got it wrong. Aren't classes and structs considered objects? Then within you put in stored properties such as types... and I guess since you can also store functions. So because you can put in functions does it make the answer to this question False?

Hate missing questions on these quizzes but I love this community~! I feel like I answered my own question but conformation would be nice. Also any tips and tricks for coding/speeding up/motivating myself through these lessons would be awesome!!!

:x: I think you are misunderstanding the question.

The question is saying "When creating objects we can only use primitive types (like String, Int, etc) as the types for stored properties True or False"

It is actually false because when creating objects we can actually have other objects as properties.

Review properties: Properties have a type, like variables and constants do. They store values, but they are part of a object. For example; we can make an object that is called Person and it has three properties: name, age, and favoriteFruit. name is a string (a primitive type), age is an Int (also primitive), and favoriteFood which is a type of a different object, Food. Pretend this class Fruit has two properties: name and isSweet.

:white_check_mark: Doing this is 100% fine Swift, because properties can have a type of a different object.

I hope this makes sense. If you have more questions, please ask below. Thanks!
