How we improved our iOS CI infrastructure with observability tools

摘要

When we upgraded to Xcode 13.1 in April 2022, we noticed a few issues such as instability of the CI tests and other problems related to the switch to Xcode 13.1.

After taking a step back, we investigated this issue by integrating some observability tools into our iOS CI development process. This gave us a comprehensive perspective of the entire process, from the beginning to the end of the UITest job. In this article, we share the improvements we made, the insights we gathered, and the impact of these improvements on the overall process and resource utilisation.
