Swift Variable Declarations

Variable declaration statements declare new variables. They can optionally assign a value to them or map those variables to on-disk files.

Declaration statements have the general form:

typename variablename (<mapping> | = initialValue ) ;

The format of the mapping expression is defined in the Mappers section. initialValue may be either an expression or a procedure call that returns a single value.

Variables can also be declared in a multivalued-procedure statement, described in another section.
