【SwiftUI】力技でTo Be Continued作った

この記事は[DeNA 24 新卒 Advent Calendar 2023](https://qiita.com/advent-calendar/2023/dena-24-newgrad)の11日目の記事です。

# はじめに
画像など使わず完全にSwiftUIのみでTo Be Continuedを再現します。

# 実装
### まずは死ぬ気でToBeContinuedViewを作ります
```swift
import SwiftUI

struct ToBeContinuedView: Shape {
    func path(in rect: CGRect) -> Path {
        var path = Path()

ここまできたらほぼ終わりです

### フォントを追加する
以下の記事の手順で[こちら](https://fonts.google.com/specimen/Caveat?preview.text=To%20Be%20Continued)のフォントを追加します。

https://qiita.com/SNQ-2001/items/6531526ab3aa51855247

### ContentViewを実装する
```swift
import SwiftUI

struct ContentView: View {
    @State private var isPresentedToBeContinued = false
    
    private let toBeContinuedViewWidth: CGFloat = 250
    
    var body: some View {
        GeometryReader { geometryProxy in
            VStack {
                Button {
                    withAnimation {
                        isPresentedToBeContinued.toggle()
                    }
                } label: {
                    Text("エンディング開始")
                }
                .buttonStyle(.borderedProminent)
            }
            .padding(20)
            .frame(maxWidth: .infinity, maxHeight: .infinity)
            .background(Color(red: 50 / 255, green: 50 / 255, blue: 50 / 255))
            .ignoresSafeArea()
            .overlay(alignment: .bottomLeading) {
                if isPresentedToBeContinued {
                    toBeContinuedView(proxy: geometryProxy)
                }
            }
        }
    }
    
    private func toBeContinuedView(proxy: GeometryProxy) -> some View {
        ToBeContinuedView()
            .fill(Color(red: 21 / 255, green: 22 / 255, blue: 16 / 255))
            .stroke(Color(red: 227 / 255, green: 227 / 255, blue: 227 / 255), lineWidth: 2.5)
            // 縦横比率を固定する
            .aspectRatio(300/68, contentMode: .fit)
            .frame(width: toBeContinuedViewWidth)
            .overlay(content: toBeContinuedTextView)
            // 画面の横幅のだけ左にずらして画面外からスタートさせる
            .transition(.move(edge: .trailing).combined(with: .offset(x: proxy.size.width)))
            .padding(20)
    }
    
    private func toBeContinuedTextView() -> some View {
        Text("To Be Continued")
            .font(.custom("Caveat-SemiBold", size: toBeContinuedViewWidth / 10))
            .foregroundStyle(Color(red: 227 / 255, green: 227 / 255, blue: 227 / 255))
            .offset(x: -15)
    }
}
```

# ちょっと解説
なんかコードだけ紹介して終わるのもちょっとアレなんで、
ポイントをいくつか紹介

### 縦横比率の固定
`aspectRatio`の第一引数に比率を渡してあげれば縦横比率が固定されます。
今回みたいに`width`だけを指定したいときは便利です。
```swift
.aspectRatio(300/68, contentMode: .fit)
```

### トランジションの合成
`transition`を`combined`で繋ぐと合成できます。
今回は「右からスライドしてくる」 & 「`proxy.size.width`の位置から移動する」の組み合わせです。
```swift
.transition(.move(edge: .trailing).combined(with: .offset(x: proxy.size.width)))
```

### カスタムフォントの使用
ここの記事に書いてあります。

# おわり
割と完成度高くできたと思います。
曲は著作権関係でやめときましたが、曲があったらもっと楽しめそうですね
