React Nativeの環境構築中になぜかpod install
に失敗して詰まり、今後も同じようなエラーに遭遇しそうだなぁと思ったので残します。
環境
react native 0.61.5 ruby 2.6.5 pod 1.9.3

解決法
ログの後半に「xcrun: error: SDK "iphoneos" cannot be located」とあるのでXcodeのパスを確認
$ sudo xcode-select --print-path /Applications/Xcode.app/Contents/Developer
Xcodeのパスが違う場所がよくわからない場所になっているので、パスを指定してあげて再度インストールすると成功する。
$ sudo xcode-select --switch /Applications/Xcode.app $ pod install
