@AliSoftware please take a look at this?

This PR seems good.

The travis failure is only due to integration specs not being rebuilt with the fixed script, we should probably fix/rebuild them along the way but I won't have time today, so postponing the merge until then. (except if @mrackwitz do rebuild them again today 😉)

I think both versions fail if there are spaces in the file name. My alternate version is this:

XCASSET_FILES="$XCASSET_FILES $(find "$PWD" -path $PWD/Pods -prune -o -name "*.xcassets"  -print | sed "s/^\\(.*\\)$/'\\1'/")"

It works for me but I've not done much testing beyond my one project that was failing.

(I can create a pull request if you like but it might be easier to include in this one?)

I had spaces in my file name because of the auto created watch kit extension. @sdarlington fixes the issue for me.

@sdarlington @spenrose

i can fix it.
i also have the problem.
but i use "-" replace spaces to solve it temporary

How about using \0?

find "$PWD" -name "*.xcassets" -not -path "$PODS_ROOT/*" -print0 | while read -d $'\0' xcasset ; do
  XCASSET_FILES="$XCASSET_FILES '$xcasset'"
done

@bonkey Looks good (though I've not tried it). Didn't know about the -d option for read.

It needs some adjustments as it looks like XCASSET_FILES in a loop is a local copy only

@bonkey seems can use \n

Found at least sth what works in my case:

    XCASSET_FILES="$XCASSET_FILES $(find "$PWD" -name "*.xcassets" -not -path "$PODS_ROOT/*" -exec echo -n " '{}'" \;)"

I still prefer @bonkey or my solution -- I think they're a lot clearer -- but if it works I'll be happy(!).

I have same issue with large project containing multiple XCassets and App extension.

• I have no spaces in the path or any of the file names or xcassets or any of the image names.
• The original fix in this pull request did not help (which is changing while read line; do to while read -d $'\n' line; do

My solution was to use @sdarlington fix:
XCASSET_FILES="$XCASSET_FILES $(find "$PWD" -path $PWD/Pods -prune -o -name "*.xcassets" -print | sed "s/^\\(.*\\)$/'\\1'/")"

changing line 172 to
while read line; do XCASSET_FILES="$XCASSET_FILES $(find "$PWD" -path $PWD/Pods -prune -o -name "*.xcassets" -print | sed "s/^\\(.*\\)$/'\\1'/")";

Here's step by step for those who has same problem:

1. Find out where your gems installed: ruby -r rubygems -e "p Gem.path"
2. modify the lines at the end of file: sudo nano /Library/Ruby/Gems/2.0.0/gems/cocoapods-0.36.3/lib/cocoapods/generator/copy_resources_script.rb (or whatever your path is) and change line 172 to the above.
3. pod update in your project

Thanks for the pull request @candyan, this unfortunately doesn't completely fix the problem so I'm going to close this in favour of #3405.
