User Defaults Editor

RocketSim’s User Defaults Editor lets you view and edit User Defaults in real time. Monitor whether a value updates after a specific action, change values on the fly, or add entirely new entries — all without writing code.

Editing values

You can edit any User Defaults value directly. Changes apply immediately, so you can see the effect in your running app. No rebuild required.

Adding new items

Add new entries of any type: strings, numbers, booleans, arrays, and dictionaries. This is useful for testing features that depend on specific User Defaults values. You can simulate states that would normally require code changes or plist edits.

Search and filter

Filter the list by value type or search for specific keys. Helpful when your app has dozens of stored preferences. You’ll find what you need without scrolling through everything.

Standard and Group defaults

Switch between your app’s standard User Defaults and App Group User Defaults. If you access a User Defaults plist from the App Directory Access page, it opens directly in the editor.
