Iterating over string in Swift to fetch mobile number

I'm trying to fetch mobile numbers from a long list of string which contains mobile number written in it separated by comma.

E.g:

8809394847, 9988338847, 9933883384, 8833938373

In my code, I have a function which accepts mobile number to do a particular job. My entire string is stored in a variable called inputData.

I tried using this code:

let mob = inputData.index(of: " ") ?? inputData.endIndex
    let mobile = inputData[..<mob]
    MyJob(phone: mobile). //Function that accepts mobile number

But it makes no sense.

My original code :

@IBAction func clickButton(_ sender: UIButton) {
    inputData = textView.text!

    MyJob(phone: mobile).  //Calling function

}

I need to run some kind of loop inside the clickButton function to fetch the mobile numbers and send it to the MyJob function one by one.

You can use split function to get array of substrings as [subStrings] like

let str = "8809394847,9988338847,9933883384, 8833938373"
let arrayOfNumbers = str.split(separator: ",")
print(arrayOfNumbers)

output: ["8809394847", "9988338847", "9933883384", "8833938373"]

iterate this array and send it to the MyJob function one by one.

Hope this helps.

You better try components separation string function

@IBAction func clickButton(_ sender: UIButton) {

  inputData = textView.text!

  var mobileNumbers = inputData.components(separatedBy: ",")

  for mobile in mobileNumbers {
     MyJob(phone: mobile) //Calling function
  }

 }

You can simply use String.components(separatedBy:) to split your String into separate phone numbers.

@IBAction func clickButton(_ sender: UIButton) {
    let numbersString = textView.text!
    let numbers = numbersString.components(separatedBy: ", ")
    for number in numbers {
        MyJob(phone: number)
    }
}

Use components(separatedBy with parameter ", " to make an array then use a loop for example

let string = "8809394847, 9988338847, 9933883384, 8833938373"
let phoneNumbers = string.components(separatedBy: ", ")
for phoneNumber in phoneNumbers {
    MyJob(phone: phoneNumber)
}
