I am having trouble converting my array of String to Currency.
I have created an extension currencyInputFormatting(), however the commas are being placed in the wrong spots.
Here is my code to add the currency to my text.
cell.balanceLabel.text? = (monthlyBalanceStringArray)[indexPath.row].currencyFormatting()
extension String {
// formatting text for currency textField
func currencyFormatting() -> String {
var number: NSNumber!
let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.maximumFractionDigits = 2
var amountWithPrefix = self
let regex = try! NSRegularExpression(pattern: "[^0-9]", options: .caseInsensitive)
amountWithPrefix = regex.stringByReplacingMatches(in: amountWithPrefix, options: NSRegularExpression.MatchingOptions(rawValue: 0), range: NSMakeRange(0, self.characters.count), withTemplate: "")
let double = (amountWithPrefix as NSString).doubleValue
number = NSNumber(value: (double))
// number = NSNumber(value: (double / 100))
guard number != 0 as NSNumber else {
return ""
}
return formatter.string(from: number)!
}

"the commas are being placed in the wrong spots." What do you mean? Can you please give an example of inputs, and expected and actual outputs. Also, always post code, data, logs, error message, etc as text (not images) so they are searchable, and can be copied when answering.

You don't need to replace any any characters using regex. Just use NSNumberFormatter
extension String {
// formatting text for currency textField
func currencyFormatting() -> String {
if let value = Double(self) {
let formatter = NumberFormatter()
formatter.numberStyle = .currency
formatter.maximumFractionDigits = 2
if let str = formatter.string(for: value) {
return str
}
}
return ""
}
}
"74154.7".currencyFormatting() // $74,154.70
"74719.4048014544".currencyFormatting() // $74,719.40

Note that if the goal is to display the currency in US$ you would need also to set a fixed locale to your formatter otherwise 100 dollars might became 100 euros.
