Answer by Govani Dhruv Vijaykumar for Prevent multiple Tap on the same UIButton

I did it like this

var callInProgress = falsefunc call(){   if callInProgress == true{     return   }   callInProgress = true  //Make it false when your task done}

it will not allow user to call the function one more time untill you make callInProgress false

This is the only thing working
