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()
- Statistics
- Task
- Info
- Basic Info / Wrapped task_info()
- Thread
- Basic Info / Wrapped task_threads(), thread_info()
- Info
Requirements
- Platforms
- iOS 10.0+
- macOS 10.12+
- Swift 5.0
Installation
