Try this. If you are opening this as a local file from your Documents folder as DriverDetails.json you can try this:

if let path = Bundle.main.path(forResource: "DriverDetails", ofType: "json") { 
    do { 
        let jsonData = try Data(contentsOf: URL(fileURLWithPath: path), options: .mappedIfSafe) 
        if let json = try JSONSerialization.jsonObject(with: jsonData, options: .mutableContainers) as? [String: Any] {
            if let jsonDriverDetails = json["Driver_Details"] as? [[String: Any]] {
                // Here you have an array of DriverDetails Dictionaries
                for jsonDriverDetail in jsonDriverDetails {
                    // Iterating through each Dictionary you can access the values using the key
                    staffNameLabel.text = jsonDriverDetails["Staff_Name"] as? String
                }
            }
         }
     } catch { print(error.localizedDescription) } 
 }
