What does below paragraph mean ? consider adding the delegate as an input to the object’s initializer

If an object must absolutely have a delegate set, consider adding the delegate as an input to the object’s initializer and marking its type as forced unwrapped using ! instead of optional via ?. This will force consumers to set the delegate before using the object.

@amanvedsharma Thanks very much for your question!

I imagine they are suggestion to do something like this:

protocol MyDelegate: class {
    func doStuff()
}

class MyClass {

    weak var delegate: MyDelegate!

    init(delegate: MyDelegate){
        self.delegate = delegate
    }

    func myFuction(){
        self.delegate.doStuff()
    }
}

I hope this helps!

All the best :slight_smile:
