How to check if value is true?

March 15, 2022

I have a struct:

public struct TextFormat: Equatable {

  var bold: Bool
  var italic: Bool
  var underline: Bool
  var strikethrough: Bool

  public init() {
    self.bold = false
    self.italic = false
    self.underline = false
    self.strikethrough = false
  }
}

var format: TextFormat = TextFormat()

How do I check if the value of format.bold == true or format.italic == true, basically I want to check which value in the struct is true and print only the value that’s true?

>Solution :

First of all the init method is not needed

To print the true values a possible solution is to add a computed property

public struct TextFormat: Equatable {
    var bold = false
    var italic = false
    var underline = false
    var strikethrough = false
    
    var status : String {
        var result = [String]()
        if bold { result.append("bold") }
        if italic { result.append("italic") }
        if underline { result.append("underline") }
        if strikethrough { result.append("strikethrough") }
        return result.joined(separator: ", ")
    }
}

Certainly there are other ways.
