Streamlining Our Icon Enum: threw an error at the end of the video.

Hi everyone, I seemed to follow along in the video just fine until the end and I've thrown an error that says: "!Missing return in a function expected to return "UIImage?" (line 54).

Here's the code:

import UIKit import Foundation

enum Icon: String { case ClearDay = "clear-day" case ClearNight = "clear-night" case Rain = "rain" case Snow = "snow" case Sleet = "sleet" case Wind = "wind" case Fog = "fog" case Cloudy = "cloudy" case PartlyCloudyDay = "partly-cloudy-day" case ParlyCloudyNight = "partly-cloudy-night"

func toImage() -> UIImage? {
    var imageName: String

    switch self {
    case .ClearDay:
        imageName = "clear-day.png"
    case .ClearNight:
        imageName = "clear-night.png"
    case .Rain:
        imageName = "rain.png"
    case .Snow:
        imageName = "snow.png"
    case .Sleet:
        imageName = "sleet.png"
    case .Wind:
        imageName = "wind.png"
    case .Fog:
        imageName = "fog.png"
    case .Cloudy:
        imageName = "cloudy.png"
    case .PartlyCloudyDay:
        imageName = "cloudy-day.png"
    case .ParlyCloudyNight:
        imageName = "cloudy-day.png"

    return UIImage(named: imageName)


    }

}

Maybe removing the return line out of the brackets will help?

Try this:

    func toImage() -> UIImage? {      
        var imageName: String

            switch self {

            case .ClearDay:
                imageName = "clear-day.png"
            case .ClearNight:
                imageName = "clear-night.png"
            case .Rain:
                imageName = "rain.png"
            case .Snow:
                imageName = "snow.png"
            case .Sleet:
                imageName = "sleet.png"
            case .Wind:
                imageName = "wind.png"
            case .Fog:
                imageName = "fog.png"
            case .Cloudy:
                imageName = "cloudy.png"
            case .PartlyCloudyDay:
                imageName = "cloudy-day.png"
            case .PartlyCloudyNight:
                imageName = "cloudy-night.png"
            default:  
                imageName = "default.png"      
            }                                                              

        return UIImage(named: imageName)  
    }
}
