If Statement With Negated Condition¶

In an “if” expression with an “else” block, avoid negation in the condition to make the code easier to read.

Examples¶

Negated Condition¶

- (void)foo:(int)bar {
  if (bar != 0) {
    [self diff];
  }
  else {
    [self same];
  }

  /* should be refactored to
  if (bar == 0) {
    [self same];
  }
  else {
    [self diff];
  }
  */
}
