Hi, i'm trying to figure out how to detect if the Mac is currently charging in my Swift application. I found lots of information regarding how to do this with UIDevice, but found no information regarding it's MacOS counterpart. Would someone mind pointing me in the right direction? All I need is a simple bool: charging - true/false. Thanks so much!
All I need is a simple bool: charging - true/false.
Do you mean:
Is connected to an external power adapter?
Is actively charging the battery?
These are different things. You can get the former with:
import IOKit.ps
let isPowerAdapterConnected = IOPSCopyExternalPowerAdapterDetails()?.takeRetainedValue() != nilThe latter is more complex. You can iterate through all the power sources looking at the
kIOPSIsChargingKeyguard let blob = IOPSCopyPowerSourcesInfo()?.takeRetainedValue() else {
return
}
guard let sources = IOPSCopyPowerSourcesList(blob)?.takeRetainedValue() as [CFTypeRef]? else {
return
}
for source in sources {
guard let sourceInfo = IOPSGetPowerSourceDescription(blob, source)?.takeRetainedValue() as? [String:Any] else {
continue
}
guard let isCharging = sourceInfo[kIOPSIsChargingKey] as? Bool else {
continue
}
print(isCharging)
}but you’ll need to handle various edge cases (Macs without a battery; Macs with an external battery, aka a UPS; and so on).
Share and Enjoy
