Changes going into the core Swift distribution must meet a very high bar as far as implementation and design, the confidence we have into committing to specific APIs (especially since we’ll have ABI stability in Swift 5), and other factors. Thus this will not really alleviate much burden on the Core team or on the community — one of the core goals of your proposal. Further, incorporating all those concerns up front when building libraries might be counterproductive.</div><div class=""><br class=""></div><div class="">FWIW, Ben Cohen and I have been talking about possibly using Swift packages as a way to seed out experimental ideas for extensions to the Standard Library. This would allow ideas to be trialed by real usage (a complaint I’ve seen about some changes we’ve made to Swift in the past). Users could build things on top of those libraries, knowing they are available as packages, and if an API “graduates” to being part of the Standard Library the user can then depend upon it being available there. If it never graduates, however, the package remains around.</div><div class=""><br class=""></div><div class="">One thing that resonates me in what you propose is about having a “well-organized effort” whose aim is to make these libraries feel cohesive and implemented well. However, given that many of these naturally fall somewhere in the spectrum of responsibilities within the Standard Library and Foundation, I think it is self-misleading to think that the Core Team or others would not be involved in these efforts if the intention is to possibly incorporate these one day into the core Swift distribution. There also may be other ways to achieve that level of cohesion in API design, such as through community discussion (possibly via the <a href="http://swift.org/" target="_blank" class="">Swift.org</a> mailing lists/forums). This discussion would not necessarily be the same as the path to “ratification” of a library into core Swift, but a step that could benefit many library authors (including considering ideas one day incorporated into the core swift). With such a mechanism many library authors could benefit even if they do not intend to have the library as part of the core distribution.</div><div class=""><br class=""></div><div class="">My apologies that these are all hand-wavy ideas, but I’m trying to paint a possible alternative way to achieve your goal of more library evolution for Swift without having such a formal work group that may be too heavy weight or too narrowly focused.</div><div class=""><br class=""></div><div class="">Ted<br class=""><div class=""><br class=""><blockquote type="cite" class=""><div class="">On Nov 7, 2017, at 9:54 AM, Dave DeLong via swift-evolution <<a href="mailto:swift-evolution@swift.org" target="_blank" class="">swift-evolution@swift.org</a>> wrote:</div><br class="m_6397394472239744289Apple-interchange-newline"><div class=""><div style="word-wrap:break-word;line-break:after-white-space" class="">Hi Swift-Evolution,<br class=""><br class="">The Standard Library's goal is to be small and targeted.

The "Non-Standard Library" will offer a well-curated, high-value collection of routines, types, and documentation to support Swift development on all platforms.<br class=""><br class=""><b class="">Goals</b><br class=""><br class="">The main goals of this effort would be:<br class=""><div class=""><ul class=""><li class="">Alleviate pressure on the Core Team while providing the developer community with functionality that normally falls under Apple's internal development umbrella.</li><li class="">Deliver authoritative, reliable, and regularly updated libraries avoiding issues faced by third-party dependencies.</li><li class="">Provide oversight, organization, and full community involvement to ensure its components are worthy, maintained, and passing a bar of need and excellence.</li></ul></div><b class="">Suggested Libraries</b><br class=""><br class="">There are several areas we think that are ripe for improvement and implementation as a non-standard library, such as (but not limited to):<br class=""><div class=""><ul class=""><li class="">A BigNum library</li><li class="">A full-featured Random library</li><li class="">A simplified date/time library</li><li class="">A library for manipulating paths (that is not based on URL or String)</li><li class="">An expanded Swift-native Geometry library and so forth.</li></ul></div>The scope and extent of the sublibraries would be proposed and debated on a parallel Non-Standard Library Evolution development list.<br class=""><br class=""><b class="">Coordination</b><br class=""><br class="">This effort would be fully coordinated with the Swift development team, respecting the team's existing commitments and responsibilities. We would request an Apple body to act as an official coordinator, enabling both oversight of this effort and to expose Apple-sourced suggestions to the Non-Standard community for action.<br class=""><br class=""><b class="">Next Steps</b><br class=""><br class="">To proceed, we need a general community consensus that this effort is worth the significant overhead it would involve.<br class=""><br class="">We must then:<br class=""><div class=""><ul class=""><li class="">Select a project lead, who appoints technical leaders from the community.</li><li class="">Recruit a core team, a small group responsible for strategic direction, pulled from experienced members well versed in contributing to Swift-dev.</li><li class="">Establish a Non-Standard Swift Evolution process, based on the one that is currently followed by Swift Evolution. Following SE practices will guarantee a consistent and excellent language experience for those developers including the Non-Standard library into their projects.</li><li class="">Build a Non-Standard Swift Evolution repository home.</li><li class="">Adopt a code license, based on Swift's current licensing.</li><li class="">Define the community working group rules and code of conduct.</li><li class="">Establish a mailing list and/or forum.</li><li class="">Begin the selection of target sublibraries and populating them by recruiting committers and contributors.</li></ul></div><b class="">Alternative Names</b><br class=""><br class="">Suggested names for this effort include the following.<br class=""><div class=""><ul class=""><li class="">Extended-Standard Library</li><li class="">Community-Standard Library</li><li class="">Non-Standard Library</li></ul></div>We are not married to any of these names and welcome alternative suggestions.<br class=""><br class=""><b class="">Measures of Success</b><br class=""><br class="">A successful Non-Standard Library will provide a stable and incrementally grown ecology of Swift frameworks that developers can depend upon with a minimum of turbulence and regret cycles. For that reason, the most successful content will be core functionality, with significant field testing prior to adoption. We recommend that NSSE follow a model of provisionary adoption and refinement before deployment to ensure any adopting code base will not be affected by later module changes.<div class=""><br class=""></div><div class="">Thanks,</div><div class=""><br class=""></div><div class="">Dave DeLong and Erica Sadun</div></div>_______________________________________________<br class="">swift-evolution mailing list<br class=""><a href="mailto:swift-evolution@swift.org" target="_blank" class="">swift-evolution@swift.org</a><br class=""><a href="https://lists.swift.org/mailman/listinfo/swift-evolution" target="_blank" class="">https://lists.swift.org/mailman/listinfo/swift-evolution</a><br class=""></div></blockquote></div><br class=""></div></div></blockquote><blockquote type="cite" class=""><div class=""><span class="">_______________________________________________</span><br class=""><span class="">swift-evolution mailing list</span><br class=""><span class=""><a href="mailto:swift-evolution@swift.org" target="_blank" class="">swift-evolution@swift.org</a></span><br class=""><span class=""><a href="https://lists.swift.org/mailman/listinfo/swift-evolution" target="_blank" class="">https://lists.swift.org/mailman/listinfo/swift-evolution</a></span><br class=""></div></blockquote></div></div>_______________________________________________<br class="">
