Get the source code from https://www.openssl.org/source/

Build it for your Mac using commands such as:
(Note these steps are based on a build script for OpenSSL 1.0.2k)

tar xzf openssl-1.something.tar.gz
cd openssl-1.something

CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
export CC
MACOSX_SDK=/Developer/SDKs/MacOSX10.12.sdk
[ -d ${MACOSX_SDK} ] || 
MACOSX_SDK=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk

./Configure debug-darwin64-x86_64-cc --openssldir="$(pwd)-x86_64"
perl -i -pe 's|static volatile sig_atomic_t intr_signal|static volatile 
int intr_signal|' crypto/ui/ui_openssl.c
perl -i -pe "s|^CC= gcc|CC= ${CC} -arch x86_64 
-mmacosx-version-min=10.6|g" Makefile
perl -i -pe "s|^CFLAG= |CFLAG= -arch x86_64 -mmacosx-version-min=10.6 
-isysroot ${MACOSX_SDK} |g" Makefile
make MAKEDEPPROG=${CC} depend
make
make test
make install

Now debug the program in openssl-1.something-x86_64/bin/openssl

(Sorry, I don't know how to tell XCode to debug a program already
compiled with the XCode command line clang)

Enjoy
