Creating NSData from NSString in Swift

Question

I\'m trying to ultimately have an NSMutableURLRequest with a valid HTTPBody, but I can\'t seem to get my string data (coming from a UITextFie

Answer 1

To create not optional data I recommend using it:

let key = "1234567"
let keyData = Data(key.utf8)

Answer 2

Swift 4.2

let data = yourString.data(using: .utf8, allowLossyConversion: true)

Answer 3

Here very simple method

let data = string.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
