Observable.create内でonNextしたらonCompletedが次の行に無いと警告するSwiftlint custom rule

Task/Promise/Future代わりにObservableを利用する場合、Observable.createするのだが、onNextは1回しかしないのでonNextの次行にonCompletedがなかったら警告する。

custom_rules:
  next_with_completed:
    regex: "\\.create\\s*\\{\\s*\\(?\\w+\\)?\\s*->\\s+Disposable in\\n[\\S\\s]*(onNext\\([\\w]+\\)|on\\(\\.next\\(\\w+\\)\\))\\n(?![^//]+\\.onCompleted)"
    message: "Must call onCompleted event next line of onNext."
    severity: warning
