DeviceKit
DeviceKit is a hardware library for iOS that provides a value-type replacement for device specifications and system state metrics. It serves as a framework for detecting device identity, hardware capabilities, display metrics, and real-time system state indicators.
The library includes tools for identifying specific device models, families, and simulator status to implement hardware-specific optimizations. It also provides a detector for physical components, such as biometric sensors and stylus support, to toggle interface features.
Additional capabilities cover display metrics analysis for screen dimensions and pixel densities, as well as system monitoring for battery levels, charging status, power modes, and available disk space.
Features
- Hardware Device Identification - Identifies specific hardware models and simulator status to implement device-specific optimizations.
- Hardware Capability Detection - Detects the presence of physical components like biometric sensors and stylus support to toggle features.
- Battery Status Monitors - Tracks current energy levels and charging states to manage background activity.
- Detailed Battery Charge Monitors - Monitors energy levels and charging states to optimize background activity and notify users.
- Power State Monitors - Monitors battery levels and power states to trigger automatic resource usage adjustments.
- Device Hardware Abstractions - Provides a value-type replacement for UIDevice for detailed hardware specifications and system metrics.
- Hardware Identifier Mappings - Maps system-level hardware identifiers to a curated set of predefined device categories and model families.
- Device State Inspection - Detects environmental conditions such as low power mode and disk space to adjust resource usage.
- System Usage Monitoring - Monitors low power mode and disk space status to adjust application resource usage.
- Display Metrics - Retrieves screen dimensions, aspect ratios, and pixel densities for responsive layout adjustments.
- Display Scaling - Retrieves screen dimensions and pixel densities to adjust layouts and scaling across Apple displays.
- Haptic Capability Detectors - Checks for hardware support for biometric sensors and stylus input to enable specific interface features.
- Delegate-Based Hardware Abstraction - Decouples hardware capability logic from specific system implementations using a hardware abstraction layer.
- Value Type Prioritization - Uses an architectural preference for immutable value types to represent device attributes and prevent state mutation.
- Lazy Environment Queries - Implements lazy querying of battery and environment data to minimize the overhead of frequent system calls.
- Device Hardware Helpers - Value-type replacement for standard device identification APIs.
- Device Utilities - Value-type replacement for UIDevice.
