In iOS applications, the main types of memory leaks are related to improper management of object references:

• Strong Reference Cycles — when two objects have strong references to each other and neither can be released.
• Leaks caused by Closures — if a closure captures self with a strong reference, it can lead to a cycle.
• Unreleased resources — objects that are not released due to lack of deinit call or improper use.

Example of a strong reference cycle:

class Person {
    var apartment: Apartment?
}

class Apartment {
    var tenant: Person?
}

let person = Person()
let apartment = Apartment()
person.apartment = apartment
apartment.tenant = person // strong reference cycle

To prevent this, weak (weak) or unowned (unowned) references are used.
