# Squirrel

🐿️ *Pronounced: Scroll-Wheel*

A menu bar app that adds scrolling to the simulator.

- For some reason, you can't scroll in Xcode's simulator.
- This app enables scrolling again!
- Features: customizable settings, made with SwiftUI, and a cute squirrel.

## Installation

You can download Squirrel on the [App Store](https://apps.apple.com/app/squirrel-for-simulator/id1669664068).

Alternatively, get the [ZIP file](https://github.com/aheze/Squirrel/releases/latest/download/Squirrel.zip), or use Homebrew:

```bash
brew install hkamran80/things/squirrel-for-simulator
```

**Note:** Squirrel requires macOS Big Sur (11.0) or higher.

## Notes

- Press <kbd>ESC</kbd> to stop scrolling in case something bugs out.
- Trackpad support is currently unstable, but most scroll wheels / mice should work.
- Customization Reference - General:
  - `Enabled` - whether Squirrel is active.
  - `Natural Scrolling` - toggles the scroll direction.
  - `Pointer Color` - the color of the cursor pointer.
  - `Pointer Size` - the length of the pointer.
  - `Pointer Opacity` - the opacity.
  - `Pointer Scale` - scale the pointer by this when scrolling starts.

  - `Inactivity Timeout` - how many seconds to wait before stopping scroll.
  - `Scroll Interval` - how often to execute a scroll step.

### How does it work?

Squirrel uses your Mac's accessibility controls to simulate a "drag" gesture.

### Apple, if you're reading this:

Please add native scroll support to the Simulator! Feels like such a small feature but it'll be very welcome.
