How to convert Data to a String
Swift version: 5.6
If you know an instance of Data contains a String and you want to convert it, you should use the String(decoding:as:) initializer, like this:
let str = String(decoding: data, as: UTF8.self)If the Data instance can’t be converted to a UTF-8 string, you’ll get sent back an empty string. This means you do need to know which format is used to store the string, but UTF-8 is usually the best to go with.
