Extracting iOS Framework within Zip file via editor script

I am having an issue trying to extract an iOS framework within a zip file via an editor script. I can extract the zip file no problem and it generates the contents, however when it tries to extract the iOS framework it has an issue trying to extract a Headers folder, which is actually an Alias (on Macs). Instead it thinks the Headers folder is a file, and just creates a file instead.

The zip file is here:
https://github.com/Estimote/iOS-SDK/archive/4.26.3.zip
And you can find the framework within the EstimoteSDK folder.

I am using this library to perform the extraction from the zip:
https://github.com/r2d2rigo/dotnetzip-for-unity

Any help would be appreciated.

 

It's an iOS framework, why would you want to extract it? Just use it as a plugin.
