Pattern: Malformed parentheses for control statement
Issue: -
if, for, while, do statements shouldn't wrap their conditionals in parentheses.
Examples of correct code:
if condition {
if (a, b) == (0, 1) {
if (a || b) && (c || d) {
if (min...max).contains(value) {
if renderGif(data) {
renderGif(data)
for item in collection {
for (key, value) in dictionary {
for (index, value) in enumerate(array) {
for var index = 0; index < 42; index++ {
guard condition else {
while condition {
} while condition {
do { ; } while condition {
switch foo {Examples of incorrect code:
↓if (condition) {
↓if(condition) {
↓if ((a || b) && (c || d)) {
↓if ((min...max).contains(value)) {
↓for (item in collection) {
↓for (var index = 0; index < 42; index++) {
↓for(item in collection) {
↓for(var index = 0; index < 42; index++) {
↓guard (condition) else {
↓while (condition) {
↓while(condition) {
} ↓while (condition) {
} ↓while(condition) {
do { ; } ↓while(condition) {
do { ; } ↓while (condition) {
↓switch (foo) {
