Chapter5 Filter Operators

example(of: “takeWhile”) {
let disposeBag = DisposeBag()
// 1
Observable.of(2, 2, 4, 4, 6, 6)
// 2
.enumerated()
// 3
.takeWhile { index, integer in
// 4
integer % 2 == 0 && index < 3
}
// 5
.map { $0.element }
// 6
.subscribe(onNext: {
print($0) })
.disposed(by: disposeBag)
}

No 2 // 2 .enumerated()
Value of type ‘Observable’ has no member ‘enumerated’
how to solve this problem ?
