http://www.ioscreator.com/tutorials/add-search-table-view-tutorial-ios8-swift

i following tutorial. lot of red errors due using named tuple, not simple array in tutorial. need tuple, can provide right code problem?

i have code:

var mydata = [data]()  // adding data array var newdata = data(category: "lorem", name: "ipsum") mydata.append(newdata)

i first error here:

controller.searchresultsupdater = self

my solution. , should add uisearchresultsupdating, uisearchcontrollerdelegate, uisearchbardelegate

var dataforsearch: [music]? = nil var searchcontroller: uisearchcontroller! var searchpredicate: nspredicate!   func updatesearchresultsforsearchcontroller(searchcontroller: uisearchcontroller) {     self.dataforsearch?.removeall(keepcapacity: false)     var searchtext = searchcontroller.searchbar.text     if searchcontroller.active == true {         searchpredicate = nspredicate(format: "namesong contains[c] %@", searchtext)         dataforsearch = self.fetchedresultscontroller?.fetchedobjects?.filter() {            return self.searchpredicate.evaluatewithobject($0)         } as! [music]?     }     self.tableview.reloaddata() }  func searchbar(searchbar: uisearchbar, selectedscopebuttonindexdidchange selectedscope: int) {     updatesearchresultsforsearchcontroller(searchcontroller) }  override func viewdidload() {     super.viewdidload()     self.tableview.delegate = self     searchcontroller = ({         var controllersearch = uisearchcontroller(searchresultscontroller: nil)         controllersearch.delegate = self         controllersearch.searchbar.delegate = self         controllersearch.definespresentationcontext = false // default false         controllersearch.hidesnavigationbarduringpresentation = true         controllersearch.searchbar.sizetofit()         controllersearch.searchresultsupdater = self          self.tableview.tableheaderview = controllersearch.searchbar         return controllersearch     })()     self.tableview.reloaddata() }
