+* **BREAKING CHANGES**:
+  - Locale is no longer part of the `locationFromAddress` and `placemarkFromAddress`, but should be set first by `setLocaleIdentifier`. This was already implemented on Android but is now working similarly on iOS.
+  - Updates documentation related to setting the locale.
+  - Added `setLocaleIdentifier` to the example app.
+  - Updates `geocoding_ios` version to 3.0.0.

-Both the `locationFromAddress` and `placemarkFromCoordinates` accept an optional `localeIdentifier` parameter. This parameter can be used to enforce the results to be formatted (and translated) according to the specified locale. The `localeIdentifier` should be formatted using the syntax: [languageCode]_[countryCode]. Use the [ISO 639-1 or ISO 639-2](http://www.loc.gov/standards/iso639-2/php/English_list.php) standard for the language code and the 2 letter [ISO 3166-1](https://en.wikipedia.org/wiki/ISO_3166-1) standard for the country code.
