Technical Notes
Legacy technologies include features, functions, classes, and methods that have been deprecated or are no longer supported. A technology identified in the ADC Reference Library as deprecated has been superseded and may become unsupported in the future. A technology identified as unsupported is no longer available from Apple for use by software or hardware developers. Legacy documents help developers understand legacy technologies, identify replacements, and update their products to run on current Apple platforms.
