While installing [React](https://flaviocopes.com/react/) Native to run a project on iOS, I run into a problem.

I went into the project's `ios` folder to run `pod install` as I was instructed to do.

But as I ran that command, I got a long error message back:

From this error I read the `error: SDK "iphoneos" cannot be located`.

That looked suspicious, right?

So I researched a bit and what fixed the problem was running the command

```bash
sudo xcode-select --switch /Applications/Xcode.app
```

Then running `pod install` again worked fine!
