Swift how to use enum to get string value

Question

I have enum:

enum NewProgramDetails: String {
    case Description = "Description", ToMode = "To Mode", From = "From", To = "To", Days = "Days"

    static let allValues = [Description, ToMode, From, To, Days]
}

I want to use this enum to display in my cell depend on indexPath:

cell.textLabel.text = NewProgramDetails.ToMode

error: Cannot assign value of type 'ViewController.NewProgramDetails' to type 'String?'

How can I use enum values to assign it to label text as a string?

Answer 1

In swift 3, you can use this

var enumValue = Customer.Physics
var str = String(describing: enumValue)

Answer 2

使用枚举的rawValue ：

cell.textLabel.text = NewProgramDetails.ToMode.rawValue

Answer 3

Other than using rawValue ,

NewProgramDetails.ToMode.rawValue // "To Mode"

you can also call String.init to get the enum value's string representation:

String(NewProgramDetails.ToMode)

This will return "ToMode" , which can be a little bit different from the rawValue you assigned. But if you are lazy enough to not assign raw values, this String.init method can be used!

I've posted a feedback to feedbackassistant with text:

let test: AVCaptureDevice.Position = .back
print("This is fail: \(test)")
