Pace

Instant desktop space switching on macOS. No animation delay.

Pace sits in your menu bar and lets you switch spaces instantly via global hotkeys or trackpad swipes — bypassing the default macOS transition animation.

Requirements

• macOS 14+
• Accessibility permission (for trackpad gesture interception and shortcut recording)

How it works

Pace intercepts horizontal dock swipe gestures via a CGEvent tap and replaces them with synthetic high-velocity swipe events, effectively skipping the animation. Global hotkeys are registered through the Carbon Event API and trigger the same synthetic switch.

This project merges logic from InstantSpaceSwitcher (hotkey-based switching) and iss (gesture interception) into a single Swift menu bar app.

Build

Pace uses Tuist to generate the Xcode project from Project.swift and Tuist/Package.swift. Tuist is pinned via mise.toml.

# Resolve SPM dependencies (required once per checkout / after pulling changes
# to Tuist/Package.swift or Tuist/Package.resolved)
tuist install

# Generate the Xcode project (no Xcode window)
tuist generate --no-open

# Build
tuist xcodebuild build -scheme Pace -configuration Debug \
  -derivedDataPath build -clonedSourcePackagesDirPath build/SourcePackages \
  -destination 'platform=macOS'

# Run locally (handles tuist install + generate + build + launch internally)
./run-menubar.sh

Test

tuist install
tuist xcodebuild test -scheme Pace -configuration Debug \
  -derivedDataPath build -clonedSourcePackagesDirPath build/SourcePackages \
  -destination 'platform=macOS'
