here code :

func sectionalert () {      var message1 = nslocalizedstring("section 1 score ", comment: "");     message1 += "\(section1score)";     message1 += nslocalizedstring(" please review before continuing", comment: "1");      var message2 = nslocalizedstring("section 2 score ", comment: "");     message2 += "\(section2score)";     message2 += nslocalizedstring(" please review before continuing", comment: "2");      var message3 = nslocalizedstring("section 3 score ", comment: "");     message3 += "\(section3score)";     message3 += nslocalizedstring(" please review before continuing", comment: "3");      if (section1score >= 10){         let alertcontroller: uialertcontroller = uialertcontroller(title: nslocalizedstring("section 1 score on 10", comment: ""),             message: " \(message1)",             preferredstyle: .alert)          let okaction = uialertaction(title: "ok", style: .default) {             action -> void in }          alertcontroller.addaction(okaction)         self.presentviewcontroller(alertcontroller, animated: true, completion: nil)      } else if (section2score >= 10){         let alertcontroller: uialertcontroller = uialertcontroller(title: nslocalizedstring("section 2 score on 10", comment: ""),             message: "\(message2)",             preferredstyle: .alert)          let okaction = uialertaction(title: "ok", style: .default) {             action -> void in }          alertcontroller.addaction(okaction)         self.presentviewcontroller(alertcontroller, animated: true, completion: nil)      } else if (section3score >= 10){         let alertcontroller: uialertcontroller = uialertcontroller(title: nslocalizedstring("section 3 score on 10", comment: ""),             message: "\(message3)",             preferredstyle: .alert)          let okaction = uialertaction(title: "ok", style: .default) {             action -> void in }          alertcontroller.addaction(okaction)         self.presentviewcontroller(alertcontroller, animated: true, completion: nil)     } }

any ideas ??

thanks !

the primary problem you're using else if. section 2 , 3 conditionals won't tested unless prior ones evaluate false.

so want change this:

if (section1score >= 10){     // … } else if (section2score >= 10){     // … } else if (section3score >= 10){     // … }

to more this:

if (section1score >= 10){     // … }  if (section2score >= 10){     // … }  if (section3score >= 10){     // … }

that said, won't able present 3 view controllers @ same time. may want update code combine messages 1 alert. (this better user experience seeing 3 modal alerts appear @ same time.)
