i18n

Interprolated strings won't parse correctly when exporting for localization. Instead use String.localizedStringWithFormat() passing in the NSLocalizedString as the first argument.

Things to remember:

• Remember to configure the scheme for the language you want to test, just updating the device isn't enough.
• Clean the project if not everything is coming through.
• The Localizable.strings portion of the .xliff document needs to have the <target> node added to it.

Interoperability with Obj C

If you have an error in your Swift code the *-Swift.h header will not build.
