Limitations ⚠️

This command line tool can only detect static strings. If you compute your localized String keys dynamically, they won't be detected by xcode-dead-string, so this won't work:

var key = "my_string_key"
if foo {
  key += "_1"
} else {
  key += "_2"
}

You can work around this by either restructuring your code to only have static Strings:

let key: String
if foo {
  key = "my_string_key_1"
} else {
  key = "my_string_key_2"
}

Or you can ignore the keys from xcode-dead-strings by adding a comment in your Localizable.strings file:

/* no_dead_string */
"my_string_key_1" = "...";

// no_dead_string
"my_string_key_1" = "...";
