ARC error in XCode

[Nubeh]

I'm using Unity 5.0.3 and I get this error in Xcode after uilding the app:

I found out that disabling ARC form the files ZipArchive and UnityZipFile by using the flag -fno-objc-arc solves the problem. That said, is it possible to not have the build error while keeping ARC enabled?

Thanks

Where do i add this flag @Nubeh ?

EDIT: nvm i found it Xcode->Build Settings->Other C/Other C++ flags

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 : "Assets/Plugins/IOS"
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.
