Question 1

How do I set up a custom backend for MissionControl?

Accepted Answer

Create a server that returns a JSON dictionary of key-value pairs, then pass the URL to MissionControl.launch() with the remoteConfigURL parameter. The README's Phase 3 shows this with an example URL and JSON structure.

Question 2

MissionControl vs Firebase Remote Config: which is better?

Accepted Answer

MissionControl offers more control with a self-hosted backend and simple API, ideal for teams wanting flexibility. Firebase Remote Config is a managed service with built-in A/B testing, but less backend customization. Choose based on your need for control versus convenience.

Question 3

Can MissionControl handle feature flags for A/B testing?

Accepted Answer

It can manage basic feature flags via boolean values in the config, but lacks built-in user segmentation or experiment analytics. You'll need to implement targeting logic separately in your app or backend for advanced A/B testing.

Question 4

How to listen for config changes in real-time?

Accepted Answer

Use NSNotificationCenter to observe MissionControl.Notification.DidRefreshConfig or implement the MissionControlDelegate protocol for callbacks on refresh success or failure, as detailed in the 'Listen for changes' section.

Question 5

What happens if the remote config server goes down?

Accepted Answer

MissionControl falls back to cached settings from disk, then local config, and finally inline fallback values, ensuring the app remains functional offline. Failures can be monitored via delegate methods or notifications.

Question 6

Is MissionControl suitable for watchOS apps?

Accepted Answer

Yes, it explicitly supports watchOS along with iOS, tvOS, and macOS, making it a good choice for managing configuration consistently across Apple platforms, as indicated in the platform badges.
