うっかりOptinalを文字列に変換してしまい、"Optinal("こんにちは")" みたいな文字列になってしまうやつをやっつけてみた( 'ω') #CodePiece

CodePiece.swift

"\(Normal() as Optional)"
// -> "Optional(description)"

"\(Force() as Optional)"
// -> "description"


// ------------------
struct Normal: CustomStringConvertible {
    var description: String { return "\(#function)" }
}

struct Force: CustomForce💪StringConvertible {
    var description: String { return "\(#function)" }
}
