How to install a private pod from git using username and token?
Here is what I have tried so far:
included the source into the pod

```
source 'https://cdn.cocoapods.org/‘
source 'https:github.com/your_repo'
target 'app' do
  use_frameworks!
  pod 'private_pod'
end

```

this doesn't work because git don't have access to pod yet
