Swift, 강의만 들으면 손에 안 익는 느낌. 그럴 땐, 직접 작성해보는 것이 중요합니다. 이 앱은 Swift 문법을 180문제로 빈틈없이 익히는 타이핑 훈련 앱입니다. 기초 문법부터 메모리 구조, ARC, 비동기 처리까지. 작은 단위로 나뉜 문제들이 자연스럽게 이해를 돕고, 손이 기억하도록 구성했습니다. 초보자에겐 Swift 입문서, 경험자에겐 완벽한 복습서. Swift 전체 문법을 커버하는 180문제 구성입니다. Swift를 그냥 배우는 게 아니라 몸에 익히는 앱입니다. 하루 30문제, 6일이면, Swift가 자연스럽게 손에 붙기 시작합니다.
