Iboutlets not working inside block swift -


i fetching request server , trying display in tablview. in process want hide spinner after fetching records. problem : associated self inside block not work. 

@iboutlet weak var spinner: uiactivityindicatorview! @iboutlet weak var customtableview: customtableview! var widgetarray :nsmutablearray = [] override func viewdidload() {     super.viewdidload()      print(dataobjects.sharedinstance.mainarray)     let appdelegate = uiapplication.sharedapplication().delegate as! appdelegate       spinner.hidden = false     spinner.startanimating()      customnetworkhit.networkhitforurl("http://winjitwinds.cloudapp.net/windapi/windapiservice.svc/getcategorydatapagewise?categoryid=1944&pageno=1", completion: {(arrayresult) -> void in          // spinner not stop animating , not hide          self.spinner.stopanimating()         self.spinner.hidden = true         print("disable spinner man")         dataobjects.sharedinstance.mainarray.addobjectsfromarray(arrayresult [anyobject])         self.widgetarray.addobjectsfromarray(arrayresult [anyobject])         self.customtableview.setuptableview(self.widgetarray)          // uitableview not reload data.          self.customtableview.reloaddata()       })

please specify mean "does not work". without it's hard know sure guess trying ui work on background thread (blocks don't run on main thread).

within block try this:

dispatch_async(dispatch_get_main_queue(), ^(){     // ui code goes here });

in swift:

dispatch_async(dispatch_get_main_queue()) {    // ui code goes here }
