SwiftUI API Key Management Guide – Secure Your App with Best Practices

API we used today: https://www.weatherapi.com/
Did you know that exposing API keys in your SwiftUI app can lead to security vulnerabilities — even if your repo is private?
In this tutorial, we’ll walk through the right way to store and access API keys in Xcode using .xcconfig files — and keep your secrets safe. 🔐

Apple doesn’t provide this out-of-the-box for SwiftUI, so we’re building it ourselves — clean, secure, and GitHub-safe.

🧐 What You’ll Learn:
✅ How to use .xcconfig files to store secrets
✅ How to inject API keys into Info.plist safely
✅ How to read secrets from SwiftUI using Bundle.main
✅ How to make secure HTTP requests with API keys

🎯 By the end, your SwiftUI app will be pulling live API data — without ever exposing your keys!
