Int64 don't show 0 when I save on Core Data

Question

this is my add button:

guard let name = texfiedldName.text else { return }
guard let phoneNumber = texfiedldAge.text else { return }
guard let email = texfiedldEmail.text else { return }

formatting text

let scanner = Scanner(string: phoneNumber)
let validCharacters = CharacterSet.decimalDigits
let startCharacters = validCharacters.union(CharacterSet(charactersIn: "+#"))
var digits: NSString?
var validNumber = ""
while !scanner.isAtEnd {
    if scanner.scanLocation == 0 {
        scanner.scanCharacters(from: startCharacters, into: &digits)
    } else {
        scanner.scanCharacters(from: validCharacters, into: &digits)
    }
    scanner.scanUpToCharacters(from: validCharacters, into: nil)
    if let digits = digits as String? {
        validNumber.append(digits)
    }
}
print(validNumber)

add to Core Data

let person = Person(context: PersistenceService.context)
person.name = name
person.number = Int64(validNumber)!
person.email = email
PersistenceService.saveContext()
self.people.append(person)

this is my output

085293173

but in the tableViewCell

85293173

can you help me please?

@vadian and why I put in another position return me the correct number in my cell? 3200582527 — Fabio, May 08 '18 at 06:38

@Martin R but I want it in Swift... my entity is in Int64... I formatting that in string? — Fabio, May 08 '18 at 07:04
@Fabio: The answer is still the same: Use a *string* to store the phone number, not an integer. That is independent of the language. — Martin R, May 08 '18 at 07:05
@Martin R if my entity is in Int64, I formatting the into String? — Fabio, May 08 '18 at 07:07
Again: Use a *String* attribute for the Core Data entity, **not** Int64. — Martin R, May 08 '18 at 07:08
The integer 0000009 is the same as just 9, but the phone number 000008 is not the same as 8, you better change the entity to string — Daniel Krom, May 08 '18 at 07:19
@DanielKrom I try but return this error: libswiftCore.dylib`_swift_runtime_on_report: -> 0x10d372e70 : pushq %rbp 0x10d372e71 : movq %rsp, %rbp 0x10d372e74 : popq %rbp 0x10d372e75 : retq 0x10d372e76 : nopw %cs:(%rax,%rax) — Fabio, May 08 '18 at 07:28
thx to MartinR and DanielKrom...the error depended on an inexplicable cash ... I created a new entity and all is done :) — Fabio, May 08 '18 at 07:51
