Code of "ReplaySubject" not working on page 70

📚 Official Books RxSwift
1

The code is not working on Xcode Version 8.3.2.
The error is on this line “print(label: “1)”, event: $0)”.
It says “Incorrect argument in call”.

The following code will work:

// 3
    subject
        .subscribe { event in
            print("1), \(event)")
        }
        .addDisposableTo(disposeBag)
    subject
        .subscribe { event in
            print("2), \(event)")
        }
        .addDisposableTo(disposeBag)

Just found out I have kept the code apeared earlier:

// 2
func print<T: CustomStringConvertible>(label: String, event: Event<T>) {
print(label, event.element ?? event.error ?? event)
}

Oh no, I can not delete my own post!

Don’t worry, I guess only the forum admins can delete posts. The important thing is you found where the issue was :slight_smile:
