If all you care about is whether or not there is a match, you do not need to capture the output of grep and then compare it; you can simply test its exit status directly:
Code:
if grep -qr FAILED ~/build_results.txt; then
      RESULT='fail'
else
      RESULT='pass'
fi
echo is a $RESULT

Or, perhaps, more optimistically:
Code:
result=success
grep -qr FAILED ~/build_results.txt && result=fail
echo is a $result

xcrun

xcrun
     xcrun -- run or locate development tools

SYNOPSIS

     xcrun [-sdk SDK] -find <tool_name>

     xcrun [-sdk SDK] [-log] <tool_name> [<tool_arguments>]

     <tool_name> [<tool_arguments>]

DESCRIPTION

     xcrun provides a means locate or invoke coexistence- and platform-aware developer tools from the command-line, without requiring users to
     modify makefiles or otherwise take laborious or inconvenient measures to adopt Xcode's multiple tool chains.

     xcode-select is used to specify which installation of Xcode is used, and may be overridden by the DEVELOPER_DIR environment variable.

     The SDK defaults to the current OS SDK, and can be specified by SDKROOT environment variable or the -sdk flag (which takes precedences over
     SDKROOT).

USAGE

     The first usage returns the full path to the found tool_name.

     The second usage executes tool_name with the given tool_arguments.

     The last syntax is when xcrun replaces any of the standard UNIX developer tools (typically in /usr/bin).  In this case, xcrun will use its
     tool name to locate the corresponding tool within evaluated DEVELOPER_DIR and SDK.

     If the tool is not named xcrun , tool_arguments are not parsed by xcrun.

OPTIONS

     -verbose
	   display information about how the redirected path is constructed.

     -no-cache
	   don't consult the cache when looking up values.  In effect, causes the cache to be refreshed.

     -sdk SDK
	   specifies which SDK to use.	Overrides any SDKROOT set in the environment.

     -log  print the full command line that is invoked.

     -find
	   print the full path to the tool.

ENVIRONMENT

     DEVELOPER_DIR - specifies the search path for locating the current developer tools (overrides xcode-select default).

     SDKROOT - specifies the SDK to use; overriden by the command line -sdk flag.

     xcrun_log - same as specifying -log

     xcrun_nocache - same as specifying -no-cache

     xcrun_verbose - same as specifying -verbose

DIAGNOSTICS

     When xcrun is invoked with the name xcrun , the flags -log and -verbose are useful debugging aids.  The flag -no-cache can be used to bypass
     cache lookup.

     When xcrun as taken the place of another tool, the arguments are those of the tool replaced, and the various xcrun flags can't be used.  In
     this case, use the specific environment variables instead.
