There is a problem with install.swift script - if you have Xcode installed in different folder than default or if you have multiple Xcode versions it either fails or installs templates in wrong Xcode version.
To fix this problem I suggest to use "xcode-select --print-path" command to get active Xcode path dynamically instead of hardcoded "/Applications/Xcode.app/Contents/Developer".
