**Severity:** Notice

**Category:** Code Style

## Description{% #description %}

This rule encourages developers to replace multiple consecutive `if` statements that compare the same value with a `switch` statement. Using a `switch` provides clearer intent, improves readability, and makes the control flow easier to follow when handling multiple discrete cases of a single variable.

To comply with this rule, identify sequences of `if` or `else if` conditions that test the same variable against different values and refactor them into a single `switch` statement. This practice leads to cleaner, more maintainable, and idiomatic Swift code. For example, instead of writing `if x == 1 { } else if x == 2 { }`, use `switch x { case 1: ... case 2: ... }`.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```swift
class Foo {
    func bar(plop: Int) {
        if plop == 1 {

        } else if plop == 2 {

        } else if plop == something {

        }
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```swift
class Foo {
    func bar(plop: Int) {
      // no else here, this example is non-sensical and should not pass
      if (x == 3) {
        if (x == 4) {
            // something
        }
      }
    }
}
```

```swift
class Foo {
    func bar(plop: Int) {
        switch plop {
            case 1:
                // something
            case 2:
                // something else
            default:
                // something else as well
        }
    }
}
