You are explicitly unwrapping the optional variable currentQuestion. When this variable is nil it will cause a crash.
Please read the Swift documentation about optional chaining: https://docs.swift.org/swift-book/LanguageGuide/OptionalChaining.html
You should safely set the text of your label as such:
lblQuestion.text = currentQuestion?.question
