How do I get the last value in a string separated by commas?

Question

I have this string

let data = 123,456,7,8,9,10

I want to extract the last value separated by a "," which in this case would be 10, and its not necessarily a two digit value.

I tried this:

var data = 123,456,7,8,9,10
data = data.last!

Answer 1

Use String method data.components(separatedBy:)

let data = "123,456,7,8,9,10"
let lastComponent = data.components(separatedBy: ",").last
print(lastComponent)
