Hello all, I am following the lesson of the day 40. And I have an Xcode error that won't let me compile the code. Compared to Paul's code, I don't see any difference. Has this happened to anyone else or do you know how to solve it? Thank you very much!!

struct Bundle {
    func decode(_ file: String) -> [String: Astronaut] {
        guard let url = self.url(forResource: file, withExtension: nil) else { //Error here: 'nil' requires a contextual type - and: Value of type 'Bundle' has no member 'url'
            fatalError("Failed to locate \(file) in bundle.") // Locate JSON
        }

        guard let data = try? Data(contentsOf: url) else {
            fatalError("Failed to load \(file) from bundle.") // Load JSON
        }

        let decoder = JSONDecoder()

        guard let loaded = try? decoder.decode([String: Astronaut].self, from: data) else {
            fatalError("Failed to decode \(file) from bundle.") // Decode JSON
        }
    }
}

What's the error?

I have pasted the code now because the image I had uploaded has not loaded. Thanks!

You're right!! I hadn't noticed, thank you very much!
