Question 1

How to validate postal codes in Swift for international apps?

Accepted Answer

Use PostalCodeValidator with a locale or region code; it supports 200+ regions via the validate() method, as shown in the README code examples. This integrates easily into iOS or macOS projects using Swift Package Manager.

Question 2

PostalCodeValidator vs CLDR for Swift projects?

Accepted Answer

PostalCodeValidator is better since CLDR deprecated postal code formats; it provides a maintained Swift-native solution, but CLDR might offer more current data if manually updated. For Swift apps, PostalCodeValidator simplifies validation without managing CLDR directly.

Question 3

Does PostalCodeValidator work for military addresses?

Accepted Answer

No, the known issues section states it doesn't include special postal codes like armed forces in Germany. You'll need to handle these cases separately or use a different validation source for such codes.

Question 4

How up-to-date is PostalCodeValidator's data?

Accepted Answer

The data is static and was retrieved on November 27, 2019, so it might be outdated. For projects needing current postal code rules, consider supplementing with live APIs or checking for library updates.

Question 5

What are alternatives for address validation in iOS?

Accepted Answer

Alternatives include third-party APIs like Google Places for full address validation, or other Swift libraries if needed. PostalCodeValidator is specific to postal codes, so it's best paired with other tools for comprehensive solutions.

Question 6

Can I use PostalCodeValidator for e-commerce shipping?

Accepted Answer

Yes, it's designed for international applications like e-commerce and shipping, but verify that the covered regions and data currency meet your needs, especially for countries with recent postal code changes.
