I’m often buried in massive server logs and need an iOS app that helps me find issues fast. It should open multi‑GB log files quickly and let me browse and search without freezing. The file must be streamed and indexed in the background (do not load the whole file into memory). I need fast regex filters to isolate relevant lines and configurable color rules for timestamps, severity levels, and other patterns. Show an interactive timeline of log activity with pinch‑to‑zoom so I can drill into spikes. The UI should stay responsive while indexing and searches run. Build it in Swift with SwiftUI, organize the code using an MVC approach, and use CocoaPods for dependencies.
