First just enable battery monitoring:

UIDevice.current.isBatteryMonitoringEnabled = true
Then you can create a computed property to return the battery level:

var batteryLevel: Float {
    return UIDevice.current.batteryLevel
}
To monitor your device battery level you can add an observer for the UIDeviceBatteryLevelDidChange notification:
