How can I use Swift to obtain the battery status of my MacBook?

edit

You can use the IOKit framework to obtain the battery status of your MacBook in Swift. Here is some sample code:

import IOKit.ps

func batteryLevel() -> Int {
   let snapshot = IOPSCopyPowerSourcesInfo().takeRetainedValue()
   let sources = IOPSCopyPowerSourcesList(snapshot).takeRetainedValue() as Array

   guard let powerInfo = IOPSGetPowerSourceDescription(snapshot, sources[0] as CFTypeRef) as? [String: Any] else { return -1 }

   let maxCapacity = powerInfo[kIOPMaxCapacityKey] as! Int
   let currentCapacity = powerInfo[kIOPCurrentCapacityKey] as! Int

   let batteryLevel = (currentCapacity * 100) / maxCapacity
   return batteryLevel
}

let level = batteryLevel()
print("Battery level: \(level)%")

This function will return the battery level as a percentage. You can then use it to display the battery status in your application or perform actions based on the battery level.
