Description

Reports an explicit → Void or → () return clause on a function declaration. Both forms are equivalent to declaring no return type at all, and Swift’s convention is to drop them.

func tick() -> Void { ... }      // FLAW
func tick() -> () { ... }        // FLAW

func tick() { ... }              // OK
func count() -> Int { ... }      // OK

Rationale

→ Void and → () say the same thing as the empty default return type. The Swift API Design Guidelines and the standard library consistently omit them, so leaving them in code signals either unfamiliarity with the convention or a literal port from another language. Cleaning them up keeps signatures uniform.

Remediation

Drop the return type:

func tick() {
    // ...
}
