Is there a way to use tabs to evenly space out description strings in Swift?

Question

Overriding the description variable of a custom class:

override var description : String {
        let mirrored_object = Mirror(reflecting: self)
        let         


        

Answer 1

Try use this method. It first calculates the max length of the property, and then uses that to pad the property names:

let maxPropertyLength: Int = mirrored_object.children.map { Int($0.label?.characters.count ?? 0) }.max() ?? 0
for attr in mirrored_object.children {
    if let propertyName = attr.label {
        str.append("\(propertyName.padding(toLength: maxPropertyLength + 2, withPad: " ", startingAt: 0)) = \(attr.value)\n")
    }
}
return str as String
