During eight months on Esri’s arcgis-maps-sdk-swift-toolkit and arcgis-maps-sdk-swift-samples, Daniel Hochhalter Ruiz delivered robust offline map workflows, advanced 3D visualization, and programmatic geometry editing tools. He implemented features such as an Offline Manager, OnDemand Map Area Selector, and a Programmatic Reticle Tool, focusing on reliability, localization, and developer onboarding. Daniel used Swift and SwiftUI to refactor UI components, streamline code, and expand test coverage, while maintaining thorough documentation and metadata. His work addressed API alignment, improved error handling, and enhanced user experience, resulting in a maintainable, scalable codebase that accelerates prototyping and supports complex GIS development scenarios.

July 2025 performance: Delivered a new programmatic geometry editing sample and reinforced the core programmatic reticle workflow in Esri/arcgis-maps-sdk-swift-samples. Key deliverables include a new Programmatic Reticle Tool Sample with a button-driven interface for creating and editing points, lines, polygons, and multipoints, along with project configuration and README updates. Core enhancements to the Geometry Editor for the Reticle Tool improve immediate UI feedback, hover state handling, and error resilience, with clearer editing feedback. PR feedback across multiple commits was incorporated to improve stability and UX. The work accelerates prototyping, improves reliability of programmatic editing, and enhances documentation for developers.

April 2025: Delivered stability improvements and developer-focused samples across two repos. Key toolkit updates include robust credential management for utility network traces—loading credentials during view initialization and safe handling of acquisition failures to prevent crashes—and UI standardization with Button.done, Button.cancel, and Button.ok, plus centralized localization of common button titles. In the samples repo, added WMTS and Web Feature Service samples with complete code, documentation, and metadata, and introduced a Blend Renderer for Hillshade, along with corresponding project/config updates. Business value: improved runtime stability, consistent UX and localization, and an expanded, well-documented sample library that accelerates integration, testing, and QA. Technologies demonstrated: Swift, UI component design, localization, error handling, and code quality improvements (reduced force unwraps) across two repos.

January 2025 focused on delivering robust offline capabilities, stabilizing core map loading paths, and cleaning and modernizing the codebase for Esri/arcgis-maps-sdk-swift-toolkit. Key features shipped include a comprehensive Offline Manager and Offline Map Infrastructure that enables creating maps from portal items, manages offline maps through OfflineMapInfo, and provides a visible download UX; plus on-demand map area download actions and related hasDownloadedMapAreas refinements. UI consistency was improved by replacing a custom button with the system button. Test coverage was expanded with OnDemandMapModel.Status tests. Major refactors simplified on-demand map models, removed legacy status checks and deprecated parameters, and PR feedback resolutions were implemented. This combination yields a more reliable offline workflow, easier maintenance, and a scalable foundation for future capabilities.
