How to Decode a String Except Html Tags Using Swift Language

1.Create a Header Class Name as Helper.Swift

// Helper.swift

static func toString(_ parameter: Any?, defaultValue: String = "") -> String

{

if let stringValue = parameter as? String {

let decodedString = String(htmlEncodedString: stringValue)

return decodedString

}

return defaultValue

}

//Extension For Html Decode

extension String

{

init(htmlEncodedString: String)

{

self.init()

guard let encodedData = htmlEncodedString.data(using: .utf8) else {

self = htmlEncodedString

return

}

let attributedOptions: [String : Any] = [

NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,

NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue

]

do {

let attributedString = try NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil)

self = attributedString.string

} catch {

print("Error: \(error)")

self = htmlEncodedString

}

Usage :

self.msg = Helper.toString(dictionary["msg"] as Any)
