Swift - add text to dictionary

While I am trying to add a value to a dictionary, it always fail while I try to set the value from my textField.text. I have a text field, that I want to add to a dictionary, with this code:

var dict = [String:AnyObject]()

dict.updateValue(usernameText.text!, forKey: "key")

print(dict["key"]!)

However, on the print it doesn't show anything. When I am setting the value as "a value" - it prints fine. How come I can't add a text field value?

What type is usernameText ? and are you certain that there is any text in it ?

try adding print(usernameText.text!) to make sure.

I tested with UITextField and could not reproduce the problem when there is text in the .text property.

Try it like this:

dict["key"] = usernameText.text!

Update:

Just tried this code: 

var dict = [String:AnyObject]()        
dict.updateValue("Foo", forKey: "key")

print(dict["key"]!)

and it prints me as I expected Foo, try the following code, setting non optional value under "key" key:

if let aText = usernameText.text {
    dict.updateValue(aText, forKey: "key")
}
