Hi there, I'm a researcher studying software evolution. As part of my current research, I'm studying the implications of open-sourcing a proprietary software, for instance, if the project succeed in attracting newcomers. Swift was in my list.
To further analyze the impacts of Swift’s migration, we analyzed the git log commit history of your project in terms of _number of contributions_, _number of newcomers_, and _number of contributors per month_. The following figure presents a temporal perspective regarding these three measures. [image: Inline image 1] Given the numbers presented in the graphic, we would like to ask Swift developers the following questions: 1. What motivated the project to open its source code at Github? How do you evaluate the benefits of this migration? 2. Does this snapshot make sense? Did you find any inconsistency on the data? 3. Do you have any internal policy to promote/attract/retain newcomers? If so, do them succeed? 4. Did you expect a high number of newcomers joining the project right after it became open-source? 5. Although several developers that joined the project placed their very first contribution in a very short amount of time, most of them did not keep contributing in the following days. Why do you believe this happens? Thanks in advance for your collaboration, Gustavo Pinto, PhD http://www.gustavopinto.org
