/**     * @brief Request authorization to a given set of sensors     *     * @discussion If the SRSensorReader instance is not authorized, this     * method must be called before any other methods. Failure to request     * authorization will cause errors to be returned from the other methods.     *     * When SensorKit prepares the prompt for display, it will look at the     * NSSensorKitUsageDetail key in your Info.plist. The value should be     * a dictionary containing usage descriptions for all of the sensors being     * requested. The description key you provide to this method must     * correspond to an entry in that dictionary. To retrieve a localized     * string, SensorKit will load your InfoPlist.strings file and try to look     * up a string using the description key you provided. If that fails,     * SensorKit will use the content provided in your Info.plist.     *     * SensorKit may decide against showing the user a prompt. For example,     * if the user has already chosen whether to grant the application access     * to all of the types provided. When that happens, your completion block     * will be called with an appropriate NSError. If the user responded to     * the prompt, your completion block will be called with a nil error.     * Changes in authorization status will delivered to the delegate in the     * sensorReader:didChangeAuthorizationStatus: method.     *     */   open class func requestAuthorization(sensors: Set<SRSensor>, completion: @escaping (Error?) -> Void) NSSensorKitUsageDetail need is a dict example: { NSSensorKitUsageDetail: { SRSensorUsagePhoneUsage: { Description: some desc } But there are other error [Reader] Error requesting authorization: Error Domain=SRErrorDomain Code=0 "No valid entitlement found" UserInfo={NSLocalizedDescription=No valid entitlement found}

I have also encountered this problem, with constant feedback from users that the widget is not displaying properly
