Check if one element in array is contained in string

Question

let preferredCountryCurrenciesSymbols = ["USD", "EUR", "GBP", "HKD", "JPY", "RUB", "AUD", "CAD"]
let currency = "USDT"

I need code which loop the array and search in the string for .contains

I've tried with this, but it's not finding it

Check if array contains part of a string in Swift?

So basically the function I need is -> Bool have it or don't have it.

The question you linked is the opposite of what you need.

You can find if any value in the array is contained within currency:

let preferredCountryCurrenciesSymbols = ["USD", "EUR", "GBP", "HKD", "JPY", "RUB", "AUD", "CAD"]
let currency = "USDT"
if preferredCountryCurrenciesSymbols.first(where: { currency.contains($0) }) != nil {
    print("found")
} else {
    print("not found")
}
