Design an iOS app that helps hardware engineers quickly browse a catalog of 100,000+ electronic components. Users should be able to stack filters—like capacitance range, tolerance, and voltage rating—and see results update immediately while the list stays buttery-smooth to scroll. Provide a clean, flexible filter panel with easy presets and a quick reset. Signed-in users can save and reuse named filter sets that sync to their account across devices. Build the UI in SwiftUI.
