Custom LLDB command that generates a cURL command from any URLRequest in Swift

.lldbinit

command regex curl 's/(.+)/expr -l Swift -O -- let anyRequest = %1; if let unwrappedRequest = (anyRequest as? URLRequest), let url = unwrappedRequest.url { var baseCommand = #"curl "\#(url.absoluteString)""#; let quote = String(UnicodeScalar(UInt8(39))); if unwrappedRequest.httpMethod == "HEAD" { baseCommand += " --head"; }; var command = [baseCommand]; if let method = unwrappedRequest.httpMethod, (method != "GET" && method != "HEAD") { command.append("-X \(method)"); }; if let headers = unwrappedRequest.allHTTPHeaderFields { for (key, value) in headers where key != "Cookie" { command.append("-H \(quote)\(key): \(value)\(quote)"); }; }; if let data = unwrappedRequest.httpBody, let body = String(data: data, encoding: .utf8) { command.append("-d \(quote)\(body)\(quote)"); }; print(command.joined(separator: " \\\n\t"));}/'

@chrisvanbuskirk please elaborate. Since this is a LLVM console command, I don't see how this version would affect performance at all? Even my original implementation wouldn't affect performance more than generally printing all over the place. But again, logging is standard practice and in most app usage, negligible.
