Question 1

How do I integrate Scyther with Firebase Crashlytics without breaking crash capture?

Accepted Answer

Initialize Crashlytics first, then Scyther, to ensure proper exception handler chaining. The Crash Logging section explicitly warns that Scyther must be started last to forward crashes to previous handlers like Crashlytics.

Question 2

Scyther vs Flipper for iOS debugging: which is better?

Accepted Answer

Scyther is a native, all-in-one toolkit integrated into your app with features like database browsing and location spoofing, while Flipper is a cross-platform desktop client. Choose Scyther for embedded debugging without external tools, but Flipper if you need multi-platform support.

Question 3

How to add custom debug screens to the Scyther menu?

Accepted Answer

Use the DeveloperOption API to append options with view controllers. The Custom Developer Options section shows examples like adding a DebugSettingsViewController, allowing seamless integration of app-specific tools.

Question 4

Does Scyther work with both SwiftUI and UIKit apps?

Accepted Answer

Yes, Scyther supports both frameworks. The Quick Start provides setup code for App (SwiftUI) and AppDelegate (UIKit), and UI tools like grid overlays are framework-agnostic, as noted in the detailed usage guide.

Question 5

Can I use Scyther to browse Realm databases?

Accepted Answer

Yes, but you need to create a custom DatabaseBrowserAdapter without adding Realm dependencies to Scyther. The Database Browser section explains how to implement adapters for third-party databases like Realm with schema and CRUD methods.

Question 6

What's the performance impact of enabling Scyther's network logging?

Accepted Answer

Scyther uses actors and AsyncStream for thread-safe logging with minimal overhead, and logs are automatically cleaned up after 7 days. However, continuous interception of all HTTP requests could add slight latency in resource-constrained environments.
