ios - using Swift to get contents of URL using NSURLSession, however, it return errors -

i've got 3 errors, "'nearbyvc.type' not confirm protocol 'uitableviewdatasource'" @ error1, "'nearbyvc.type' not have member named 'session'" @ error2 , "expected declaration" @ error3. however, cannot figure out why such errors appeared.if know hot solve, please me.

// ※error1※ class nearbyvc: uiviewcontroller,uitableviewdelegate,uitableviewdatasource{  @iboutlet var listview: uitableview? var tabledata = []  override func viewdidload() {     super.viewdidload()      // additional setup after loading view. }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }  func tableview(tableview: uitableview,numberofrowsinsection section: int) -> int{     return 1 }  func tableview(tableview: uitableview,cellforrowatindexpath indexpath: nsindexpath) -> uitableview{     let cell:uitableviewcell = uitableviewcell(style: uitableviewcellstyle.subtitle, reuseidentifier: "mytestcell")     let rowdata:nsdictionary = self.tabledata[indexpath.row] nsdictionary      cell.textlabel.text = "row#\(indexpath.row)"     cell.detailtextlabel?.text = "subtitle #\(indexpath.row)" }  let url = nsurl(string:"http:~~") let session = nsurlsession.sharedsession()  // ※error2※ let task:nsurlsessiontask = session.datataskwithurl(url,completionhandler:apihandler)  //use separate handler function in lieu of doing inline clarity func apihandler(data:nsdata!,response:nsurlresponse!,error:nserror!){     if (error != nil) {         println("api error:\(error),\(error.userinfo)")     }     var jsonerror:nserror?     var json:nsdictionary = nsjsonserialization.jsonobjectwithdata(data, options: nsjsonreadingoptions.mutablecontainers, error: &jsonerror) nsdictionary     if (jsonerror != nil) {         println("error parsing json: \(jsonerror)")     }     else{         let status:string? = json["msg"] as? string         println("servar status:\(status)")     } } // ※error3※ task.resume() } 

• error1:

  func tableview(tableview: uitableview,cellforrowatindexpath indexpath: nsindexpath) -> uitableview{     let cell:uitableviewcell = uitableviewcell(style: uitableviewcellstyle.subtitle, reuseidentifier: "mytestcell")     let rowdata:nsdictionary = self.tabledata[indexpath.row] nsdictionary      cell.textlabel.text = "row#\(indexpath.row)"     cell.detailtextlabel?.text = "subtitle #\(indexpath.row)" } 

  i won't analize in body, should return uitableviewcell not uitableview

  as specified in protocol:

  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell 

• error2:

  let url = nsurl(string:"http:~~") let session = nsurlsession.sharedsession()  // ※error2※ let task:nsurlsessiontask = session.datataskwithurl(url,completionhandler:apihandler) 

  you cannot initialize constant in class , use initialize one, move function.

• error3

  fix error2 fix error3.

disclamer: haven't analised whole code you've written , have identified causes of compiler error.
