Description

Reports a trailing ; at the end of a Swift statement. Semicolons in Swift are optional; they are only required to separate two statements sharing the same physical line. A ; that has nothing after it on the line is pure noise.

let a = 1;                       // FLAW
print(a);                        // FLAW

let c = 3; let d = 4             // OK — `;` separates two statements
let s = "x;y"                    // OK — `;` inside a string literal

Rationale

Trailing semicolons are usually leftovers from porting code from C, Objective-C, or Java. They add nothing and dilute the Swift style.

Remediation

Delete the trailing ;.

let a = 1
print(a)
