Clone boringssl
git clone https://github.com/google/boringssl.git boringssl
Build boringssl
cd boringssl
mkdir build && cd build
./build.ios
build.ios is my build script
#!/bin/bash
set -e

Merge libcrypto & libssl
If you want a standalone lib (name like libboringssl.a), you can use below shell script
#!/bin/bash
set -e
export IPHONEOS_DEPLOYMENT_TARGET="9.0"
function merge_crypto_ssl_lib () {
cd crypto && ar x libcrypto.a
cd ../ssl && ar x libssl.a && cd ..
ar r libboringssl.a ./crypto/*.o ./ssl/*.o
}

Create OpenSSL.framework
After build libboringssl.a, if you want using it in swift, you will need a modulemap, so we create a framework.
the framework must be named OpenSSL.framework
mkdir OpenSSL.framework
cp libboringssl.a OpenSSL.framework/OpenSSL
mkdir OpenSSL.framework/Headers
cp ../include/openssl/* OpenSSL.framework/Headers/
mkdir OpenSSL.framework/Modules
modulemap_file=OpenSSL.framework/Modules/module.modulemap
echo "framework module OpenSSL {" > ${modulemap_file}
echo " export *" >> ${modulemap_file}
echo "}" >> ${modulemap_file}
