Having all branches in a switch or if chain with the same implementation is an error. Either a copy-paste error was made and something different should be executed, or there shouldn't be a switch/if chain at all.

Noncompliant Code Example

if b == 0 {  // Noncompliant
  doOneMoreThing()
} else {
  doOneMoreThing()
}

switch i {  // Noncompliant
  case 1:
    doSomething()
  case 2:
    doSomething()
  case 3:
    doSomething()
  default:
    doSomething()
}

Exceptions

This rule does not apply to if chains without else-s, or to switch-es without default clauses.

if b == 0 {    //no issue, this could have been done on purpose to make the code more readable
  doSomething()
} else if b == 1 {
  doSomething()
}
