around this issue error has to be cast to CLError so the code property can be accessed, see as follows:
if let error = error as? CLError {
    switch error.code {
       case CLError.Code.geocodeFoundPartialResult:  print("\(#function): No results")
       default: print("\(#function): Error reports \((error as NSError).localizedDescription)")
    }
}
    let geocoder = CLGeocoder()
    let location = CLLocation(latitude: 23.8759, longitude: 90.3795)
    geocoder.reverseGeocodeLocation(location) {placemarks, error in

        if let error = error as? CLError {
            NSLog("Geocode failed with error: \(error)")
            let message: String
            switch error.code {
            case CLError.Code.geocodeFoundNoResult:
                message = "kCLErrorGeocodeFoundNoResult"
            case CLError.Code.geocodeCanceled:
                message = "kCLErrorGeocodeCanceled"
            case CLError.Code.geocodeFoundPartialResult:
                message = "kCLErrorGeocodeFoundNoResult"
            default: message = (error as NSError).description
            }
            return
        }

    }

Compile error with `let` in Swift switch statements


Tag : swift , By : stan

this one helps. multiItemList[1..multiItemList.endIndex] is not an array. You have to convert it to an array first. Change the line into the following:
let cdr: String[] = Array(multiItemList[1..multiItemList.endIndex])

With these it helps I don't know about exact error, but you can do conversion of [[Int]] something like this.
var days: [[Int]] = [[1], [1,2,3], [7]]

let numberStr = ["Zero","One","Two","Three","Four","Five","Six","Seven","Eight","Nine"]

let daysInString = days.map { (intList) -> [String] in
    return intList.map({ (intValue) -> String in
        return numberStr[intValue]
    })
}
print(daysInString)

// Output : [["One"], ["One", "Two", "Three"], ["Seven"]]

swift set value with switch will got error: expected initial value after '='

it helps some times I would wonder if there's any short cut way to set value of colorPredicate
let colorPredicate: NSPredicate = { (color: Color) -> NSPredicate in
    switch color {
        case .black:   return predicateForBlack()
        case .white:   return predicateForWhite()
    }
}(color)
let variable = { switch { ... } }()
let variable = switch { ... }
var lookup: [Color: NSPredicate] = [:]
lookup[.black] = NSPredicate(format: "color = black")
lookup[.white] = NSPredicate(format: "color = white")
let colorPredicate = lookup[color]

Swift: How to access a Switch Statement in a Swift file (error: Statements are not allowed at the top level)?

I wish this help you You are getting this error because you have your switch statement just sitting inside some class or struct (it's not clear where you have this code implemented). To fix your error you will need to put that switch inside a function. Perhaps you could create a function called setTheme, like so:
var theme = UserDefaults.standard.string(forKey: "themes")

var background: UIColor?
var labelColor: UIColor?
var buttonColor: UIColor?

func setTheme() {
  //First, check to make sure theme is not nil
  guard let theme = self.theme else { return }
  switch theme {
  case "Red":
    background = UIColor(named: "darkRed")
    labelColor = UIColor(named: "labelRed")
    buttonColor = UIColor(named: "buttonRed")
  case "Blue":
    background = UIColor(named: "darkBlue")
    labelColor = UIColor(named: "labelBlue")
    buttonColor = UIColor(named: "buttonBlue")
  default:
    return
  }
}
var background: UIColor? {
  guard let theme = self.theme else { return nil }
  switch theme {
    case "Red": return UIColor(named: "darkRed")
    case "Blue": return UIColor(named: "darkBlue")
    default: return nil
  }
}

How to describe error from Alamofire using switch case in Swift?

To fix the issue you can do As per Jayesh Thanki says you can identify the server error using status code and for internet connectivity you can use NetworkReachabilityManager of Alamofire. Write following code in viewDidLoad():
var networkManager: NetworkReachabilityManager = NetworkReachabilityManager()!
networkManager.startListening()
networkManager.listener = { (status) -> Void in
if status == NetworkReachabilityManager.NetworkReachabilityStatus.notReachable {
   print("No internet available")
}else{
   print("Internet available")
}
