PostalCodeValidator
A validator for postal codes with support for 200+ regions.
import Foundation import PostalCodeValidator if let validator = PostalCodeValidator(locale: .current) { // United States (US) validator.validate(postalCode: "95014")) // true validator.validate(postalCode: "22162-1010") // true validator.validate(postalCode: "1234567")) // false validator.validate(postalCode: "INVALID")) // false } // 248 regions supported if let validator = PostalCodeValidator(regionCode: "JP") { // Japan (JP) validator.validate(postalCode: "154-0023")) // true validator.validate(postalCode: "12345") // false }
Note: Only the region of a locale is used to determine validation rules. To validate the postal code for a particular region, you can construct a locale using an identifier with the
"und"
language code.
Requirements
- Swift 4.0+
Installation
Swift Package Manager
Add the PostalCodeValidator package to your target dependencies in Package.swift
:
import PackageDescription let package = Package( name: "YourProject", dependencies: [ .package( url: "https://github.com/FormatterKit/PostalCodeValidator", from: "0.1.0" ), ] )
Then run the swift build
command to build your project.
Known Issues
- Armed forces in Germany (and likely other countries) use special postal codes, which aren't included in the upstream data source. This will cause validation of these postal codes to fail. so validation will fail for these postal codes. (Thanks for pointing this out, @timohetzel)
Additional Details
The CLDR previously maintained a list of postal code formats, but that information was deprecated in v27.
Following the guidance of the
