– I am using zip plugin in my app for download files from cloud.This is working well with Android But Error in making build for iPhone.

– it shows " null! " in pop up after completion of build.

– If i remove plugin table from my build.settings then it will not give error but zip file handling is not working.

– Please give me a solution ,if anyone have successfully implement zip plugin in iPhone.
