Hello
I'm making an app that displays large Double numbers, for example 86,859.002. The problem is how do I change the comma( , ) with the dot ( . )

Thank you

When you show numeric values for users, you use NumberFormatter:

Code Block let value: Double = 86_859.002
let nf = NumberFormatter()
nf.numberStyle = .decimal
nf.thousandSeparator = "."
nf.decimalSeparator = ","
nf.maximumFractionDigits = 3
print(nf.string(from: value as NSNumber) ?? "")
//->86.859,002

You usually set an appropriate Locale instead of specifying thousandSeparator explicitly.
An example.

Code Block let nfEs = NumberFormatter()
nfEs.numberStyle = .decimal
nfEs.locale = Locale(identifier: "es_ES")
nfEs.maximumFractionDigits = 3
print(nfEs.string(from: value as NSNumber) ?? "")
//->86.859,002
