ios - How to access elements from an NSObject in swift? -

i've set variables object

import uikit class speedtestresult: nsobject {     var testtime: nsdate? } 

then in controller set object , pass class store it:

testresult.testtime = nsdate() speedtestmanager().addtestresult(testresult) 

i need store object , access elements within in view later, have:

import foundation class speedtestmanager : nsobject {     var testresultarray = [nsobject]()     func addtestresult(testresult: nsobject) {         testresultarray.append(testresult)         print("printing testresultarray: \(testresultarray)")      } } 

but when try print the object

printing testresultarray: [<projectname.speedtestresult: 0x127b85e50>] 

how access elements within object , store object , retrieve later use in view?

class testresult : nsobject, nssecurecoding {     var testtime: nsdate?      override init() {         super.init()     }      @objc required init?(coder decoder: nscoder) {         self.testtime = decoder.decodeobjectforkey("testtime") as? nsdate     }      @objc func encodewithcoder(encoder: nscoder) {         encoder.encodeobject(self.testtime, forkey: "testtime")     }      @objc static func supportssecurecoding() -> bool {         return true     }      override var description: string {         return string.init(format: "testresult: %@", self.testtime ?? "null")     } }  class speedtestmanager : nsobject, nssecurecoding {     var testresultarray = [nsobject]()      func addtestresult(testresult: nsobject) {         testresultarray.append(testresult)         print("printing testresultarray: \(testresultarray)")     }      override init() {         super.init()     }      @objc func encodewithcoder(encoder: nscoder) {         encoder.encodeobject(self.testresultarray, forkey: "testresultarray")     }      @objc required init?(coder decoder: nscoder) {         self.testresultarray = decoder.decodeobjectforkey("testresultarray") as! [nsobject]     }      @objc static func supportssecurecoding() -> bool {         return true     }      override var description: string {         return string.init(format: "speedmanager: [%@]", self.testresultarray.map({"\($0)"}).joinwithseparator(","))     } }  class testviewcontroller: uiviewcontroller {      override func viewdidload() {         super.viewdidload()           let testresult = testresult()             testresult.testtime = nsdate()          let speedmanager = speedtestmanager()             speedmanager.addtestresult(testresult)          nsuserdefaults.standarduserdefaults().setobject(nskeyedarchiver.archiveddatawithrootobject(speedmanager), forkey: "speedmanager")         nsuserdefaults.standarduserdefaults().synchronize()          if let archivedspeedmanager = nsuserdefaults.standarduserdefaults().objectforkey("speedmanager") as? nsdata {             let unarchivedspeedmanager = nskeyedunarchiver.unarchiveobjectwithdata(archivedspeedmanager)             print("speedmanager: \(unarchivedspeedmanager ?? "null")")         }         else {             print("failed unarchive speed manager")         }     } }
