一晩かかってもダウンロードできなかったXCodeが、よーやくダウンロードできた。オフィシャルのサイトは途中からのダウンロードのリジュームできないから、クラウドの端末でダウロードした後にOneDriveにコピーして、OneDriveからダウンロード。
XCodeインストール
Xcode_10.1.xipってファイルを展開して、アプリケーションフォルダにいれる。初期の起動もやってみて成功！
Command Line Toolsのインストール
こっちもダウンロードしたものをそのままインストールで成功！
ダメ元だったので、なんだうまく行っている感があってドキドキ。
サンプルプロジェクトの作成と実行
適当なディレクトリで作業
react-native init AwesomeProject
なんか、がしゃがしゃ動き出してreact-nativeインストールが始まった。どうなるかな。。途中、選択する状態になったので、HomeBrewの方を選択。
あれ？途中rubyらしき文言がなんども出てくる。へー。
……結構時間かかるのね。
あー、エラー出たわ。

太字のところやってみる。なんか、ごちゃごちゃ色々出て。

だって。結局Cのコンパイラが必要なのかな。いや、エラーにはなってないから、どっちかというと「SDK “iphoneos” cannot be located」てのが問題っぽいな。
調べてみる。
（メモ）xcrunでsdkが見つからないエラーが出る場合の対処@Qiita, shouta-dev様
なんか、パスの問題っぽい？以下を実行してパスを通す。
sudo xcode-select –switch /Applications/Xcode.app/Contents/Developer/
そして、再度該当のディレクトリで以下コマンドでインストール。
$ pod install

Generating Pods project
Integrating client project[!] Please close any current Xcode sessions and use `AwesomeProject.xcworkspace` for this project from now on.
Pod installation complete! There are 28 dependencies from the Podfile and 26 total pods installed.
おー、なんかうまくいったっぽい！
サンプルを実行してみる
プロジェクトディレクトリで、以下のコマンドを実行。
react-native run-ios
info Found Xcode workspace “AwesomeProject.xcworkspace”
info Launching iPhone X (iOS 12.1)
info Building (using “xcodebuild -workspace AwesomeProject.xcworkspace -configuration Debug -scheme AwesomeProject -destination id=D82DC4D8-796F-4199-8EE1-F220A239395A”)
………….
おおお！なんかエミュレータが立ち上がった！！！
すげー！嬉しい！
そして、案の定、超重い！！！！
でもよしとする！
これが実機で動いたら嬉しいなぁ。とりあえずここまで！
