string - How to get first word from sentence in Swift -

i trying first word string sentence variable. how that? have local notification , need use it's message first word variable, possible? localnotifications use localnotificationhelper library easier handling. maybe there logic problem not think so. more not know enough options in swift language.

edit: have namefield.text! in nsuserdefaults array. need delete message first word array. right remove first object array not solution me because need delete namefield.text! array when localnotification pops out , user click on button.

here create notification message:

localnotificationhelper.sharedinstance().schedulenotificationwithkey("text", title: "see options(left)", message: namefield.text!+"some text", date: deadlinepicker.date, userinfo: userinfo) 

now need message:namefield.text! variable @ app launch.

this how trigger notification button actions:

nsnotificationcenter.defaultcenter().addobserver(self, selector: "somefunction:", name: identifier, object: nil) 

you can split sentence using white space char , extracting first element.

let sentence = "what wonderful world" if let firstword = sentence.characters.split(" ").first.map(string.init) {     print(firstword) // "what" }
