✍️ Sample Swift Questions & Answers
1. What is the primary advantage of ISO 20022's structured data fields over MT free-form text fields?
Structured data fields in ISO 20022 enable automated processing, reduce manual intervention, and improve data quality compared to unstructured MT free-form fields.
2. What key data element does ISO 20022 introduce that MT messages lacked?
ISO 20022 supports structured remittance data, LEIs, and purpose codes that enable end-to-end automation and regulatory reporting.
3. What does Swift's `Sendable` protocol communicate about a type?
`Sendable` marks types whose values can be safely shared across concurrency domains (actors or tasks) because they don't allow shared mutable state.
4. Under the Wolfsberg Group principles, which due diligence standard applies when a correspondent bank cannot adequately assess the AML risks of its respondent bank?
Enhanced Due Diligence is required when standard KYB measures are insufficient to assess risks posed by a respondent bank relationship.
5. Why is documentation important in Swift risk management?
This is fundamental to Swift practice. It creates an audit trail, supports decision-making, and demonstrates due diligence represents the professional standard for risk management in the Swift certification framework.
6. A `RecipeParser` must support JSON, XML, and CSV formats. You want to add new formats without modifying the parser. Which design embodies the Open/Closed Principle in Swift?
Protocol-based strategy injection lets you add `YAMLParser` later by writing a new conformance, leaving `RecipeParser` itself unchanged — open for extension, closed for modification.
