How to disable toolbar item?

Question

How can I disable toolbar item by tag?

I've tried this method:

for item in (navigationController?.toolbarItems)! {
    if item.tag == 1 {
        item.enabled = false   
    }
}

but I do not know why, it did not work. How can I fix my code?

My solution was:

var items = (navigationController?.toolbar.items)!
for item: UIBarButtonItem in items {
    if item.tag == 1 {
        item.enabled = true
    }
}
