I have just moved a large existing XCode workspace to XCode 10.2.1. In one of the MacOS projects, the target includes a "Copy Bundle Resources" build step to copy various files, including a number of PNG files. This has worked for years without problems on XCode 7 and earlier, but now I get a slew of the following pair or error messages:
"unable to find utility "pngcrush", not a developer tool or in PATH"
and
"Command CopyPNGFile emitted errors but did not return a nonzero exit code to indicate failure"
"pngcrush" does exist in "/Applications/Xcode.app/Contents/Developer/usr/bin/pngcrush". The target does appear to build successfully despite the fact that errors arr reported. What can I do to fix this problem?
Thank You
Larry
