Swift NumberFormat returns 0.00

I am trying to format a number from 1000 to $1,000.00 or 12.99 to $12.99 or 100 to $100.00 (etc)

let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = .decimal
let formattedNumberTotalCost = numberFormatter.string(from: NSNumber(value:self.itemCost))
//return 1,000
let totalCostStringLeft = String(format: "$%.02f", formattedNumberTotalCost!)
//returns 0.00 SHOULD return $1,000.00
leftui.text = totalCostStringLeft
//shows 0.00

What am I doing wrong here?

Just to provide a complete answer here, the NumberFormatter will do all you require - you just need to tell it to format the string as a currency.

Change:

numberFormatter.numberStyle = .decimal

to:

numberFormatter.numberStyle = .currency

and the work is done. Drop the assignment to totalCostStringLeft and assign

leftui.text = formattedNumberTotalCost

Your answer wasn't working as it tried to combine two methods of formatting numbers as strings. The particular error was using a "%f" formatting string and then passing a string where it expected a floating-point value.
