The right answer on this question seems to be "True", but not the "False" as you indicate. Please explain

Hi Andrea,

The only acceptable answer is:

We add a third key value pair to the dictionary.

Why?

Because at the very top it says:

// Given the following code:

var dict = [1: "someValue", 2: "anotherValue"]
dict.updateValue("yetAnoterValue", forKey: 3) // add third item to dictionary

for (key, value) in dict { // I added this to see the results in the playground
    print(value)
}

If a 3rd value already existed, then it would update the value but given the specific code in the challenge, no third value existed and so only one answer is correct.

I hope that helps,

Mike

PPS: I would recommend to always play with examples in the Playground to get a feel for how to work with the code and see how it responds when you make changes.
