Using the Fastlane Spaceship Tunes can I create a new language for existing app? - fastlane

Question

I would like to use the Fastlane Spaceship library for the iTunes Connect API to create a new language. For example, I already have a new version that is editable and has the English (U.S.) language set as primary, I would like to add the language French. Can I do this programmatically or do I have to use Apple's UI?

Answer 1

Looking at the code of deliver, you can do the following:
# Makes sure all languages we need are actually created
def verify_available_languages!(options)
# Collect all languages we need
# We only care about languages from user provided values
# as the other languages are on iTC already anyway
v = options[:app].edit_version
UI.user_error!("Could not find a version to edit for app '#{options[:app].name}', the app metadata is read-only currently") unless v
enabled_languages = []
LOCALISED_VERSION_VALUES.each do |key|
current = options[key]
next unless current && current.kind_of?(Hash)
current.each do |language, value|
enabled_languages << language unless enabled_languages.include?(language)
end
end
if enabled_languages.count > 0
v.create_languages(enabled_languages)
lng_text = "language"
lng_text += "s" if enabled_languages.count != 1
UI.message("Activating #{lng_text} #{enabled_languages.join(', ')}...")
v.save!
end
true
end
So basically use this method to create a new language:
v.create_languages(enabled_languages)
