What are the security considerations when using Swift for app development?

Security considerations in using Swift for the development of apps involve leveraging its strong type safety, optionals, and memory management to avoid common vulnerabilities such as null pointer exceptions and buffer overflows. Type safety and optionals in Swift prevent most errors and crashes at runtime, while access control restricts access to sensitive code. The key best practices that can guard against breaches and attacks include secure data storage, input validation, and proper handling of sensitive information. Swift uses ARC for automatic memory management, reducing risks related to manual memory handling, hence making the development process more secure.
