SOLVED: Phone regex giving out of bounds error

Forums > Swift
@Vendetagainst  

Hi all,

I have a function written with Combine to validate a phone number:

        @Published var phone : String = ""
        @Published var isPhoneValid : Bool = false
        func validatePhone() {
            $phone.map { phone in
                let regex = try! NSRegularExpression(pattern: "([+]?1+[-]?)?+([(]?+([0-9]{3})?+[)]?)?+[-]?+[0-9]{3}+[-]?+[0-9]{4}")
                return regex.firstMatch(in: self.phone, options: [], range: NSRange(location: 0, length: phone.utf16.count)) != nil
            }
            .assign(to: &$isPhoneValid)
        }

The phone number is modified via a TextField in SwiftUI.

However, it is giving me this error:

Thread 1: "*** -[NSRegularExpression enumerateMatchesInString:options:range:usingBlock:]: Range or index out of bounds"

I have the exact same code to validate emails and that works perfectly. Why is this out of range? Thanks!

I figured it out, I had to change self.phone to phone, so now the code is 

@Published var phone : String = ""
@Published var isPhoneValid : Bool = false

func validatePhone() {
            $phone.map { phone in
                let regex = try! NSRegularExpression(pattern: "([+]?1+[-]?)?+([(]?+([0-9]{3})?+[)]?)?+[-]?+[0-9]{3}+[-]?+[0-9]{4}")
                return regex.firstMatch(in: phone, options: [], range: NSRange(location: 0, length: phone.utf16.count)) != nil
            }
            .assign(to: &$isPhoneValid)
        }

Do you have examples of the input you are, uh, inputting when you get the error?

   

@Vendetagainst  

The app was initially crashing whenever I inputted a number.

If you check my above post, I solved it.
