Cleanup

[brodycj]

From review of PR #56 (watch2 support), I have a feeling that we should be able to clean up both the source code and all of the tests. I am raising this for future consideration and discussion.

Starting to add a list:

• use const & let instead of var, especially in new code (noticed after merging PR Support watch2 apps/extensions #56)
• look for ways to make the code easier to read & understand, especially the code added in PRs Support watch2 apps/extensions #56 & Test coverage: addTarget add to main project as dependency #76

Regarding code readability, are you thinking to enhance dependency lookup ability, or a more general thought? If the former, I have a few thoughts based on work in #76:

• Xcode links dependencies sort of messily, but helper functions could be exposed to help with this.
• The addTarget function could/should expose easier data about any generated dependencies it adds via addTargetDependency (the new UUIDs generated from addTargetDependency aren't in turn exposed through the response object of addTarget).

I was thinking more general, dependency lookup ideas sound good. -- Sent from my mobile
