Big Mountain Studio is the iOS-development teaching brand of Mark Moeykens, a SwiftUI specialist whose courses focus on the depth of Apple's declarative UI framework. He has been publishing SwiftUI material continuously since the framework's 2019 release — uniquely well-positioned to track the API as it evolves between iOS versions.
The CourseFlix listing reflects that specialisation: SwiftUI Essentials (the canonical intro), SwiftData Mastery in SwiftUI (Apple's modern persistence framework), and AI Mastery in SwiftUI (integrating LLMs into iOS apps). Material is paid and aimed at iOS developers building real apps on the SwiftUI track rather than maintaining legacy UIKit codebases.
