How am i supposed to be able to change the content of a constant? Shouldn't it be a variable like in the video?

You ask me to do this:

let currencies = ["US":"Dollar","UK":"Pound","JP":"Yen"] let ukCurrency = currencies.removeValueForKey("UK")

but shouldn't it be like this?:

var currencies = ["US":"Dollar","UK":"Pound","JP":"Yen"] let ukCurrency = currencies.removeValueForKey("UK")

You are right, Michael. It should be like var currencies.

Ok, thanks a lot! This is the kind of stuff that confuses a newbee like me. :-) (And it seems it's not the only place in the course with mistakes like this)
