How to convert Any? to Data in swift [duplicate]

Question

I need to convert from type Any? to Data.

something like this

func getItem(item:Any?) {
    let data = convertToData(item)
}

Answer 1

You can do like this:

func getItem(item:Any?) {
    if let data = item as? Data {
      // do your thing
    }else {
      // not convertible to Data
    }
}

Answer 2

You can't convert Any? to data because Any? does not have a known type. It's literally any type at all (or nil, since you have an optional Any. you can use a conditional cast to try to cast your value to data, but it may fail:

func getItem(item:Any?) {
    guard let data = Data(item) else {
        return
    }
}
