Mach-Swift

Introduction

You can easily get information from Mach.

The framework wrapped Mach functions in Swift.
It provides the following information.

• Host
  • Statistics
    • Virtual Memory Statistics / Wrapped host_statistics(HOST_VM_INFO)
    • CPU Load Info / Wrapped host_statistics(HOST_CPU_LOAD_INFO)
  • Info
    • Basic Info / Wrapped host_info(HOST_BASIC_INFO)
  • Processor
    • CPU Load Info / Wrapped host_processor_info()
• Task
  • Info
    • Basic Info / Wrapped task_info()
  • Thread
    • Basic Info / Wrapped task_threads(), thread_info()

Requirements

• Platforms
  • iOS 10.0+
  • macOS 10.12+
• Swift 5.0

Installation

Carthage
