18-Variadic Parameters in Functions in Swift | iOS | MacOSX | iPhone | iPad | iOS Apps Development
Variadic Parameters:
• A variadic parameter accepts zero or more values of a specified type.
• You use a variadic parameter to specify that the parameter can be passed a varying number of input values when the function is called.
• Write variadic parameters by inserting three period characters (...) after the parameter’s type name.
• The values passed to a variadic parameter are made available within the function’s body as an array of the appropriate type.
