Build performance can be analyzed in Xcode to speed up your builds. This can quickly speed up your workflow and save a lot of time during the day for all developers working on the project. Slow builds often distract us as they enable us to focus on distractions like social media and Slack. By Antoine Van Der Lee.
By investigating your build performance and investing some time to improve where possible, you’ll see that you can make progress with a few small steps. Author made their WeTransfer’s incremental build time 4x faster using several optimizations. Let’s dive into the options we have today:
- Measuring build performance using the Xcode Build Timeline
- Build performance insights with Build Timing Summary
- Optimizing build phases
- Type checking of functions and expressions
- Build settings to speed up build performance
- Swift Package Build Plugins
Now and then, it’s good to revisit your Xcode build times. You can benefit from every second you gain, and remember that it builds up over time: a second for every build is a minute for every 60 builds you do. Improvements can be made throughout project settings, build phases, and code-type checking improvements. Good read!
