Instead, any `install` we implement will likely install the <b class="">built products</b> of a package. That's a pretty substantial difference vs the other package managers which use `install`. It also means that we likely won't need an update/upgrade command for installed products at all.</div><div class=""><br class=""></div><div class="">With the exception of CocoaPods, it appears that the other package managers that use `install` for what I'm calling "resolve" are package managers for non-compiled languages. There's no real difference between a source package and a library product for them; sources can be pulled down and then used by other clients directly. However, in Swift, you need to actually build your dependencies before they become available. [Hat tip to Martin Waitz, who just brought this up as well].</div><div class=""><br class=""></div><div class="">Additionally, I don't think we have any aspirations of making it easy to install even built dependencies into some global location that would get automatically searched by every other package. Instead, we want to have "hermetic builds", where the entire dependency graph is explicit and self-contained (with the exception of dependencies provided by your OS, like system frameworks). So our `install` would really serve quite a different purpose than e.g. yarn's `global install`.</div><div class=""><br class=""></div><div class="">FWIW, I don't think most beginning users will ever even have to know about or use the `resolve` verb; you can do everything you need to with `swift build`, `swift update`, etc which implicitly run `resolve` for you. The more important parts of this proposal, in my opinion, are the <b class="">behavior</b> of `resolve` (which will usually be implicit), and the "Package.resolved" file. I agree with Jon that the name `resolve` isn't super clear re: the fact that it actually fetches the dependencies that it resolves when needed, but since invoking this verb directly is already an advanced-user feature I'm not too concerned about that – and I'd like it to match the name of the "Package.resolved" file, which is the most accurate and descriptive name we've come up with for that file.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>- Rick</div><br class=""><div><blockquote type="cite" class=""><div class="">On Apr 30, 2017, at 10:50 AM, David Hart <<a href="mailto:david@hartbit.com" class="">david@hartbit.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><p style="box-sizing: border-box; margin-bottom: 16px; color: rgb(36, 41, 46); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol'; font-size: 16px; background-color: rgb(255, 255, 255); margin-top: 0px !important;" class="">Hi Rick,</p><p style="box-sizing: border-box; margin-top: 0px; margin-bottom: 16px; color: rgb(36, 41, 46); font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Helvetica, Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol'; font-size: 16px; background-color: rgb(255, 255, 255);" class="">Thanks for taking the time to reply.

My biggest reservation with the word "install" is that it really sounds like it should install things into the system, or another shareable location, instead of fetching dependencies into the dependency location for a single top-level package. We might actually want to add a real "install" command that does some type of installation some day in the future, though we might also choose to forever leave that sort of thing to your system package manager. And while there is some precedence for other package managers using "install" to fetch dependencies, I think there's broader precedence for it meaning to either install things into the system, or at least create an installable "build root", with e.g. `make install`, `xcodebuild install`, `brew install`, etc.</div><div class=""><br class=""></div><div class="">I just did a quick survey of the same package managers I surveyed previously to see if they all used this term, and here's what I found:</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; line-height: normal;" class=""><b class="">yarn</b>: `install`</div><div style="margin: 0px; line-height: normal;" class=""><b class="">composer</b>: `install`</div><div style="margin: 0px; line-height: normal;" class=""><b class="">cargo</b>: No true equivalent, just supprts `update` or `build`.

We expect that the decision not to use this extension will be controversial, as following established precedent is valuable. However, we think that a "lockfile" is a very poor name for this concept, and that using that name would cause confusion when we re-introduce pins.
