cyclomatic_complexity wrong estimate ?

Describe the bug

I might be missing something but this code:

    func testCYC(bool: Bool) {
        if bool {
            print("it is true")
        }
        print("it is default")
    }

has 2 paths of execution

and if we follow the cyclomatic complexity formula where M = E - N + 2*P, this produces M = 2. However when I change the cyclomatic_complexity warning to 1, no warning is displayed. I feel like SwiftLint treats this to have a complexity of 1 and I am not sure why.

Is this a bug ?

For the record: https://github.com/terryyin/lizard produces M = 2 for the same code snippet which is what I'd expect.

cyclomatic_complexity:
  warning: 1

No source file or test is named. Start with the cyclomatic_complexity rule, reproduce the report using the shown Swift function and warning threshold of 1, and trace how the rule counts branches. Done means the behavior matches the expected complexity and a regression test covers this example.
