How to properly validate if any string is a valid bitcoin address?

[djalfirevic]

Is there any method where you can post a string, and that it returns whether this is a valid address or not?

I've tried to use something like this

private func isValidAddress() -> Bool {
    if let _ = try? BitcoinAddress(cashaddr: address) {
        return true
    } else if let _ = try? BitcoinAddress(legacy: address) {
        return true
    }
        
    return true
}

Thats actually the correct way of validating an address.
Only I would change the last return and actually pass the address 😜
