Swift 3 / Xcode 8 - How to change the native language of my App?

Question

I’m finishing an application and I couldn’t help but notice that some components of my app are in English:

How to change the app’s native language?
How to make it change automatically according to the language of my device?

Answer 1

To do this, you must use Portuguese as a language in your project.

By default, the base language is English. To add another language, go to:

1. Access your . xcodeproject;
2. In the upper left corner, choose your project instead of your target;
3. Under "Localizations", add the language in question.

By doing this, Xcode gives you the option to translate all documents from your project (applicable, usually . string, . xib and . storyboard).

If you add a file after configuring the new language and want to include it in Localizations also, you must access:

4. Click on "Locate..."

5. Add the missing language.

If you’re using Portuguese as the language on your device, this will cause iOS to "translate" system components into your app.

To change only the base language, go to the folder where your project is located and open the contents of the project package: Then open the file project.pbxproj with the Text Editor. Once done, give a Command+F and look for "English". Now it’s easy, just change the English for Portuguese and the en for pt:
