Stack

Swift, SwiftUI, MapKit

Features

• Real-time weather and wave conditions for five Michigan beaches
• NWS alerts shown per beach
• Beach detail view combining weather, buoy, and alert data into one screen
• Map view showing all five beaches

Architecture

Two-person project. The app calls a custom FastAPI backend that handles all the data. The frontend doesn't pull from NWS or NDBC directly. It calls one endpoint per beach and gets back everything it needs in a single response.

Map view. All five beaches are pinned on a MapKit view. Tapping a beach opens its detail screen.

Beach detail view. Each beach has a detail view showing current conditions, forecast, wave height, water temperature, and any active NWS alerts. All of this comes from one backend call to /beaches/{id}.

Data flow. The app hits the backend on Render, gets back a combined dataset, and maps it to SwiftUI views.

Requirements

• Xcode 16+
• iOS 18+

Setup

git clone https://github.com/jaidenhenley/Swift-MichiganAPIWeather.git

Open in Xcode and run on a physical device or Simulator. The app points to the deployed backend on Render so no local server setup is needed.
