The Swift(x, cgopts) calling sequence translates Maple code to Swift code.

- If the parameter x is an algebraic expression, then a Swift statement assigning the expression to a variable is generated.

- If x is a list of equations $\mathrm{nm}=\mathrm{expr}$, where $\mathrm{nm}$ is a name and $\mathrm{expr}$ is an algebraic expression, then this is understood as a sequence of assignment statements.  In this case, the equivalent sequence of Swift assignment statements is generated.

- If x is a procedure, then a Swift function is generated which is equivalent to the procedure, along with any necessary import statements.

The parameter cgopts may include one or more CodeGeneration options, as described in CodeGenerationOptions.
