The "use" line in the swift3 section is wrong. Your config tells the proxy to load that module from the swift project (ie from swift import swift3). However, that won't work because swift3 isn't shipped with swift. Instead you need to have something like "use = egg:swift3#middleware".

For more info on how the paste deploy config works, see http://pythonpaste.org/deploy/#config-format

Searching online revealed similar issues when swift3 wasn't installed, but i have checked the following things below and it looks like swift3 is installed. Python isn't my main language so still a bit lost and finding my way around the language.
