Script fails when "VendorFrameworks" does not exist

[wojciech-kulik]

Great job, thank you very much for this library, you saved me a lot of time.

Only one thing is missing in the script:
mkdir -p "$SWIFT_OUTPUT_PATH"
Without -p parameter it fails, because "VendorFrameworks" directory does not exist yet.

Also you can check out my modifications I had to do in order to run it on earlier iOS versions:

Sorry for the late reply, just fixed the parameter issue, and I've fixed the version related issue based on your comment.
