A strings file (a file with a .strings file extension) is a resource file that stores localized user-facing text.
The file format consists of key-value pairs where the key (used as parameters in methods) appears on the left of the expression and the localized string value appears on the right, as in:
/* Class = "UILabel"; text = "Baths:"; ObjectID = "2c7-xk-az0"; */"2c7-xk-az0.text" = "Baths:";For user-facing text in user interface files, Xcode creates the base language strings files for you, but you can also create strings files for text that you use in your code.
