iOS example failing using Bazel version 1.1.0

Hello,

Using Bazel version 1.1.0 installed using Homebrew and following the steps on the documentation [https://docs.bazel.build/versions/master/tutorial/ios-app.html](url), I got the following error trying to build the iOS project :
```

'single_file' is no longer supported. use allow_single_file instead. You can use --incompatible_disable_deprecated_attr_params=false to temporarily disable this check.

With `--incompatible_disable_deprecated_attr_params=false` I'm getting another error :

```

```

If i understand correctly the example project is not up to date with the latest version ?
What's the new equivalent of `non_propagated_deps` ?

Thanks !
