Worked on stabilizing iOS build compatibility for the wireapp/core-crypto repository by addressing deployment target inconsistencies. Focused on updating the iOS deployment target across multiple project files to align with app version 16.4, this effort resolved a deployment mismatch that could have led to runtime issues and integration problems. The work involved careful build configuration management using Makefile and Swift, ensuring that the core-crypto library remained compatible with the main iOS application. By establishing a consistent deployment target, the changes improved build stability, enhanced CI/CD reliability, and reduced the risk of downstream integration errors for ongoing iOS development.
