01. SwiftUI & Apple Human Interface Guidelines

SwiftUI provides a declarative syntax for constructing iOS, iPadOS, and watchOS interfaces. Integrated directly into iOS rendering pipelines, SwiftUI views automatically adapt across dynamic type, dark mode, and accessibility (VoiceOver) settings.

02. iOS Keychain & Hardware Security Enclave

Sensitive tokens and cryptographic private keys are backed by the Apple Secure Enclave hardware processor. RAFly configures biometric FaceID authentication checks before accessing secure keychain items.
