Convert string to base64 in Swift 3
<pre><code>let strsize = 10_000_000
let tries = 100
var longstring:String = "a"

for i in 1...strsize {
longstring += "a"
}

for i in 1..&lt;2 {
let basestring = NSData(base64EncodedString: longstring, options: .IgnoreUnknownCharacters)
print(basestring)
}
</code></pre>

<p>Writing a code in command prompt. What is the correct code to write for Swift 3 which I been getting <code>use of unresolved identifier NSData</code> . Most of the tutorials on encoding string to base64 aren't working.</p>

<p>This is working for you on Linux or Mac?
