Functions that take a variable number of arguments have proven to be an effective tool in Swift. Up to now, these functions could only accept a single type of argument. Authors have worked around this restriction by using less specific types like Any or by creating lots of overloaded boilerplate code at each argument arity.
Generic programming provides an effective answer to these challenges. This proposal seeks to unify Swift’s generic programming capabilities with its variable-arity programming features by adding variadic generics to Swift.
