Since spec.add_development_dependency "rake" is already in the gemspec template, we don't need it in the Gemfile and we should always defer to the gemspec for our dependencies except for advanced use cases.
This should fix the following case which uses "HTBResources.bundle" as resource.
```
% rake
ERROR! An iOS application cannot be installed if it contains a directory called `resources'. Please rename the directory at path `vendor/Pods/Resources/HTBResources.bundle' to, for instance, `vendor/Pods/Resources/assets'.
````
it cause an error If app.resources_dirs has nested array
app.resources_dirs << ['Images']
```
