Worked on the Esri/arcgis-maps-sdk-swift-toolkit repository to implement a centralized code signing configuration aimed at stabilizing continuous integration and streamlining build processes. The approach involved introducing a TestRunner.xcconfig file to standardize code signing across all build configurations, defaulting to automatic signing to reduce manual intervention. Both Debug and Release targets were updated to reference this centralized configuration, enhancing consistency and maintainability. This change led to fewer signing-related build failures, faster CI cycles, and simplified onboarding for new contributors. The work demonstrated proficiency in Xcode configuration, iOS development, and the use of Swift within modern CI/CD workflows.
