Swift spritekit set userdata

Question

In my quick spritekit game I want to set a custom value in the sprite, I am trying to do it like this

p.userData?.setValue(value: "Hello", forKey: "c")

But when I try to do it, it says "Couldn't find an overload for 'setValue' that takes the supplied arguments."

So the main question is:

How do I set a custom value in a sprite?

The first argument in the method has no external parameter name, so it must be

p.userData?.setValue("Hello", forKey: "c")

or better (since userData

is NSMutableDictionary

and does not encode the key value, magic is required here):

p.userData?.setObject("Hello", forKey: "c")

Note also (as noted in the comment) that you must create the dictionary first:

p.userData = NSMutableDictionary()
p.userData?.setObject("Hello", forKey: "c")

or, alternatively, assign the dictionary with your keys and values:

p.userData = ["c" : "Hello"]
