XCode error - denied (13)?

I get this weird error in XCode upon attempting a build:

rsync: send_files failed to open "/Users/User/App/platforms/ios/www/img/imgName.png": Permission denied (13)
rsync error: some files could not be transferred (code 23) at /BuildRoot/Library/Caches/com.apple.xbs/Sources/rsync/rsync-51/rsync/main.c(996) [sender=2.6.9]
Error occured on copying www. Code: 23
Command /bin/sh failed with exit code 3

Its as if these images are locked. In the normal folder they are not, but in this folder I cannot view the properties.

How do fix this?

First fix try: Remove the iOS platform and re-add it.

Tried that.

I’ve also tried to change permissions on the folder and on the images themselves now.

No help.

And it seems this is the only error!

I had to add myself to the access list on each of the restricted images. Most odd, never had to do this before, but at least it worked!

For this issue, anyway.
