To-do's for UniZip for Unity & XCode:

• add "PluginsCode>iOS>ZipArchive" files & folder to Unity project "Assets\Plugins\iOS"
• After that copy from package UnityZip: ">Asset>Plugins" (folders, files) & add to your project VTDB: "\Assets\Plugins"

Alterations for UniZip for iOS successful build:

• If package is newly imported after above setup:
  (1) Open "ZipArchive.mm" file and REMOVE:

-line 270[dc release]
-line 271[gregorian release]
-line 327[comp release]
-line 328[gregorian release]
-line 40[super delloc]

(2) Open "UnityZipFile.mm" file and REMOVE:

-line 32[zip release]
-line 35[list release]
-line 59[zip release]

-Before Build in XCode select "unity framework" from "unity iPhone" and go to "build settings>other>flags" add "-lz" symbol.
