Base iOS client version 3.5.2 is a build number 2259. Base 2.3 from January 2013 was a build number 270. Roughly 2000 builds in 5 years means roughly 8 builds every week, and if you won’t optimize it to be a streamlined task, it can become a painful experience.
If I told you Base iOS client takes around 3.5 minutes for a clean build on a decent MacBook Pro (Mid 2015) you would probably say it’s not that bad, considering around 2000 classes and 30+ cocoapods. However, since we haven’t ever worked specifically on build time optimization, we surely could do something to cut it down a bit.
