How can I prevent retain cycles in my code?

How can I prevent retain cycles in my code?

To prevent retain cycles, you can use weak references for delegates and closures. This allows objects to be deallocated.

Can you give me an example of using weak references?

Sure! In Swift, you can declare a delegate as 'weak' like this: 'weak var delegate: MyDelegate?'. This prevents a retain cycle.

What are some common scenarios where retain cycles occur?

Common scenarios include closures capturing self strongly, and delegates not being declared as weak.

How can I detect retain cycles in my application?

You can use memory graph debugging tools available in Xcode to visualize and detect retain cycles in your application.
