Method: Xcodeproj::Project::Object::XCBuildConfiguration#resolve_build_setting

Defined in:
lib/xcodeproj/project/object/build_configuration.rb

#resolve_build_setting(key, root_target = nil, previous_key = nil) ⇒ String

Gets the value for the given build setting considering any configuration file present and resolving inheritance between them. It also takes in consideration environment variables.

Parameters:

  • key (String) —

    the key of the build setting.

  • root_target (PBXNativeTarget) (defaults to: nil) —

    use this to resolve complete recursion between project and targets.

  • previous_key (String) (defaults to: nil) —

    use this to resolve complete recursion between different build settings.

Returns:

  • (String) —

    The value of the build setting
