Why does an iOS app developed using Unity 4.x SDK report an error when uploaded to the App Store?

When you package and upload an app developed using Unity 4.x SDK directly to the App Store, you may receive the following error message:

The iOS dynamic library inside the SDK v4.x for Unity has a simulator architecture, which the App Store does not allow. In order to launch and test the app, the simulator architecture in the SDK needs to be deleted. To do so, take the following steps:

1. In Xcode, select New Run Script Phase.

   

2. Add the following script to automatically delete the simulator architecture in the SDK when packaging:

   
   

   _36

   #!/bin/sh

   _36

   _36

   # Strip invalid architectures

   _36

   _36

   strip_invalid_archs() {

   _36

   binary="$1"

   _36

   echo "current binary ${binary}"

   _36

   # Get architectures for current file

   _36

   archs="$(lipo -info "$binary" | rev | cut -d ':' -f1 | rev)"

   _36

   stripped=""

   _36

   for arch in $archs; do

   _36

   if ! [[ "${ARCHS}" == *"$arch"* ]]; then

   _36

   if [ -f "$binary" ]; then

   _36

   # Strip non-valid architectures in-place

   _36

   lipo -remove "$arch" -output "$binary" "$binary" || exit 1

   _36

   stripped="$stripped $arch"

   _36

   _36

   fi

   _36

   done

   _36

   if [[ "$stripped" ]]; then

   _36

   _36

   _36

   }

   _36
