Thanks how do I clean the build folder

backend code `$postdata = json_decode( file_get_contents( "php://input" ), TRUE ); //$id = $postdata[ "email" ]; //$name = $postdata[ "password" ]; $result[ 'response' ] = "Success"; $result[ 'username' ] = "Mohammad Tariq Shamim"; // Store values in an array $returnValue = array( $result ); $array['data'] = $returnValue; // Send back request in JSON format echo json_encode( $array ); //echo json_encode( array( 'response' => 'No data found for ' . $_POST[ 'email' ] ) );

struct ApiResponse<T: Decodable>: Decodable {     let status: Int     let data: T?     let error: String? }
