if you want to build a house, you use a blueprint. A blueprint shows the features of your house, such as the kitchen, bathrooms, and bedrooms. When you use a blueprint to build multiple houses, you know that the houses will look similar. In programming, a type is like a blueprint, and an instance is like a house that you built from the blueprint. In a type, features are called properties, and be..

I got found this book in the apple books app. so I just want to develop the app. so let me try it. experiment “Use \() to include a floating-point calculation in a string and to include someone’s name in a greeting."

Now I take one more step. This is the first question var gemCounter = 1 moveForward() moveForward() collectGem() gemCounter = 1 comment) I can set a var statement in this way quest 2 = incrementing variable this means increasing var. var gemCounter = 0 while !isBlocked { while !isBlocked { if isOnGem { collectGem() gemCounter = gemCounter + 1 } moveForward() } turnRight() } comment) 큰 범위(while)에..

A algorithm is a set of rules and instructions you use solve the problem. For example, a navigation app uses an algorithm to figure out the fastest path to where you want to go. the skill you are adding now is the process of writing and tweaking code so you can use it in different situations. this puzzle has many different solutions, so trust your instincts and try different ideas until one work..

Yes, I can use the condition after the while statement. Quest 1 while !isBlocked { moveForward() if isOnOpenSwitch { moveForward() } else if isonClosedSwitch { toggleSwitch () } } while 스테이트먼트 쓸때 첫 조건은 그냥 앞으로 나아가라고 해도 된다. 이 점을 생각해내기가 어려웠음. Quest 2 func turnAndCollectGem() { moveForward() turnLeft() moveForward() collectGem() turnRight() } while !isBlocked { turnAndColllectGem () } tip. In coding..

1. 부정을 이런식으로 표현합니다. ! 를 문장 앞에 써 준다는 게 함정. 2. func 은 문장 맨 밑에서 정의해 주거나 앞에서 정의해 주거나 상관없음. 3. AND = &&. ; NOT = ! ; OR = ||

what I have learned until now 1) if statement. if condition { 명령문 } else if condition { 명령문 } 2) boolean statement. : a condition like "true" or "false" if statement 안에 차례로 명령문을 쓸 수 있다. func 문법을 배우고 있습니다. unless I would forget.

swipe 가 아니라 swift 였다. 이름을 착각. 지금 손이 가는대로 닥치는대로 아이폰 앱을 만들기 위해 노력하고 있다. swift fundamental 책을 다운 받아서 읽어보고 거기에 나오는 예제들을 하고 있다. basic to code 1 - it's like a childish game for code. but I have to do these things as well. I don't know how long it takes for my coding journey. today I learned "for i in 1.... 6" loop 기능이라고 한다. 반복하길 원할 때 쓰는 기능. 앱에 원하는 기능. 1. expiration date 기능. 삽입 2. 인앱 결제. (만기되었을 때 바로 결제..
