Change the tip percentage picker to show a new screen rather than using a segmented control, and give it a wider range of options – everything from 0% to 100%. Tip: use the range 0..<101 for your range rather than a fixed array.

I can't solve the second part of the problem

I change the array like this

  let tipPercentages = [1..<101]

But i i have an erro in the view

Can some one give me some tips?

let tipPercentages = (1..<101)

Paul is telling you that you should no longer use an array at all. Instead, you should just enter the range when creating the picker.
