Function should have at least one blank line after it

function-whitespace

Every function and method declaration should have one blank line before and after itself. An exception to this rule are functions that are declared at the start of a file (only need one blank line after their declaration) or at the end of a file (only need one blank line before their declaration). Comments immediately before a function declaration (no blank lines between them and the function) are considered to be part of the declaration.

func function1() {
  var text = 1

Force casts should be avoided
Open

        let payload = (packet.protocolParser as! UDPProtocolParser).payload
Severity: Minor
Found in src/IPStack/UDPDirectStack.swift by tailor

forced-type-cast

Avoid using the forced form of the type cast operator (as!) because Swift is not able to determine at compile time if the type conversion will succeed. In the event of an unsuccessful conversion, a runtime error will be triggered. The conditional form of the type cast operator (as?) is safer and should be used when possible.

Preferred

if let movie = item as? Movie {
    print("Movie: '\(movie.name)', dir. \(movie.director)")
}

Not Preferred

let movie = item as! Movie
print("Movie: '\(movie.name)', dir. \(movie.director)")
