how to parse first name and last name from pancard using Visionkit in ios swift?

Question

I have been trying to parse pan card details to appropriate fields. But I could not parse correctly. Here I have used regex to find pan card number and date of birth and results perfect. But I could not able find the first name and last name correctly because position are changing.

There are two type of Pan card:

1.) Pan card one contains first name, last name, pan card number, dob. 2.) Pan card second contains Name: user name, father's Name: user father name, pan card number and dob

Here is the block three different text:

Pan card Type: 2

Here is code for finding first name and last name: Here lines array are block detected text converted into array.

   var lines: [String] = []
            detectedText.enumerateLines { textLine, _ in
                lines.append(textLine)
            }
            print(lines)

    for (key, value) in lines.enumerated() {
                print("i:::", value)
                if self.validatePANCardNumber(value) == true {

                    print("pan card:::", value)

                }
                if self.validateDOB(value) == true {
                    print("dob pan:::", value)
                }

                if value.contains("/ Name") {

                   print("Item \(key + 1):value: \(lines[key + 1])")
                   let f_name = lines[key + 1]
                   print("first Name::", f_name)

                }

                if value.contains("/ Father's Name") {

                    print("Item \(key + 1):value: \(lines[key + 1])")
                    let last_name = lines[key + 1]
                    print("last Name::", last_name)

                }


            }
