After failure you need to download:
https://github.com/opencv/opencv_3rdparty/blob/ippicv/master_20170418/ippicv/ippicv_2017u2_mac_intel64_20170418.tgz

And put the library into:
~/opencv/ios/build/build-iphonesimulator/3rdparty/ippicv
Then re-run command!

For god's sake, cmake only downloads the i386 ippicv prebuilt library.

In addition for a correct build, you need to add the following to the Info.plist:

    <key>UIDeviceFamily</key>
    <array>
        <integer>1</integer>
        <integer>2</integer>
    </array>

For having full bitcode enabled, you need to add the following to the python buildscript in line #149:

        if self.dynamic:
            buildcmd += [
                "IPHONEOS_DEPLOYMENT_TARGET=8.0",
                "ONLY_ACTIVE_ARCH=NO",
                "BITCODE_GENERATION_MODE=bitcode"
            ]
