A bitrise bash script to take codecov from a previous `swift test --enable-code-coverage` step and generate some basic human readable stats.

bitrise_swift_codecov.sh

#!/usr/bin/env bash
# fail if any commands fails
set -e



##
## INPUTS
## - $CODECOV_JSON - The location of the JSON file produced by
##                   swift test --enable-code-coverage
## - $PRINT_STDOUT - 'true' by default, but if 'false' then will not
##                   output the whole codecov table to stdout.
##
## OUTPUTS
## - $CODECOV    - Overally code coverage percent.
## - codecov.txt - Code coverage in a file.
## - shield      - Code coverge in a format shield.io recognizes
##
