#expand_build_settings(string, configuration) ⇒ String

Recursively resolves build settings in any string for the given configuration. This includes xcconfig expansion and handling for the :rfc1034identifier. Unresolved settings are passed unchanged, e.g. $(UNRESOLVED_SETTING_NAME).

Parameters:

  • string (String) —

    Any string that may include build settings to be resolved

  • configuration (String) —

    Name of any valid configuration for this target

Returns:

  • (String) —

    A copy of the original string with all embedded build settings expanded

#expanded_build_setting(setting_name, configuration) ⇒ String?

Layer on top of #resolved_build_setting to recursively expand all build settings as they would be resolved in Xcode. Calls #expand_build_settings on the value returned by #resolved_build_setting, with the exception of anything defined in #fixed_build_settings. Those settings are returned directly.

Parameters:

  • setting_name (String) —

    Name of any valid build setting for this target

  • configuration (String) —

    Name of any valid configuration for this target

Returns:

  • (String, nil) —

    The build setting value with all embedded settings expanded or nil if not found

#fixed_build_settings ⇒ Hash

List of build settings with values not present in the configuration.

Returns:

  • (Hash) —
