eul

Actively maintained fork of gao-sun/eul with Xcode 26 / macOS compatibility fixes. Full credits and original project by @gao-sun.

What's new in this fork (2026)

• Fixed build compatibility with Xcode 26 and modern macOS
• Disabled ENABLE_USER_SCRIPT_SANDBOXING to unblock the SwiftFormat build phase
• Fixed SDKROOT resolution (was causing "invalid absolute path 'macosx'" error)
• Replaced deprecated kIOMainPortDefault with availability-guarded fallback for macOS < 12
• Refactored BluetoothStore to use modern APIs without deprecated IOBluetooth framework
• Updated entitlements across all widget extensions

Highlights

• Dark Mode compatible
• Big Sur widgets out of the box
• Bluetooth battery level
• Written in SwiftUI (as much as possible)

macOS 10.15 minimum for SwiftUI support
