FAQ

When should I use the Swift API Client?

If your project is in Swift or partially in Swift, you should use the Swift API Client. We don't support Swift in our Objective-C API Client.

When should I not migrate to the Swift API Client?

If your project is Objective-C only and you don't plan to use Swift, it is maybe better to continue to use the Objective-C API Client.

Also, you should know that query.queryType, query.removeWordsIfNoResult and query.typoTolerance are not accessible in Objective-C.

Can I still use the Objective-C API Client?

Yes. If you are using the Objective-C API Client and do not want to upgrade then you can stick to it. We will continue to update and support it.
