swift - Storing an XML element in a string -

i using swxmlhash parse xml webpage

let xml = swxmlhash.parse(data) println(xml["root"]["schedule"]["date"].element?.text) 

this prints out element want. however, cannot seem store in string.

i declare string

var getxmlitem: string 

and try set equal xml element want:

getxmlitem = xml["root"]["schedule"]["date"].element?.text 

but gives me error:

value of optional type 'string?' not unwrapped; did mean use '!' or '?'?

is not way set equal xml? still learning swift confusing me.

swift takes hardline between values can null , values cannot null. thinktext optional within swxmlhash framrwork. try this:

getxmlitem = xml["root"]["schedule"]["date"].element?.text! 

you need sure text isn't nil though.

an alternative declare getxmlitem optional string:

var getxmlitem : string? 

what prefer swift infer type automatically:

var getxmlitem = xml["root"]["schedule"]["date"].element?.text // getxmlitem string?
