I’d like to integrate tailor for swift (http://tailor.sh) into my build pipeline, but I don’t seem to know where to get started. When I added the script to my build phases in Xcode bitrise doesn’t start tailor because it’s not installed on the system. Is it somehow possible to have tailor installed on the build machine?
Absolutely!
You can install any tool, see: http://devcenter.bitrise.io/tips-and-tricks/install-additional-tools/
Once installed it’s up to you how you want to run it, if it’s an Xcode build phase script that’s ok too, or you can run the tool with e.g. a Script step too.
If you have any questions, just let us know!
