Worked on improving map rendering consistency in the maplibre-native repository, focusing on environments such as CarPlay and devices with varying screen densities. Addressed a key bug by implementing a scale factor utility to correct map view dimensions, ensuring accurate rendering across different displays. Synchronized the Metal view’s drawable size with the view scale factor after attachment to the display hierarchy, which resolved issues with mis-sized renders on multiple devices. Utilized Objective-C and Objective-C++ for these changes, applying expertise in CarPlay development, cross-platform workflows, and Metal to deliver more stable and visually consistent map experiences for end-users across iOS and macOS.
