Does SWIFT cost money?

Is there a fee associated with using SWIFT for international financial transactions? As a professional practitioner in the field of cryptocurrency and finance, I understand the importance of minimizing costs and maximizing efficiency in financial operations. Could you elaborate on the potential costs and charges that may be incurred when utilizing SWIFT for cross-border payments or transfers? Additionally, are there any alternative methods or solutions that could potentially offer a more cost-effective option for conducting international financial transactions?
