उपयोग के उदाहरण

Swift

Swift

guard let device = device as? DeviceCameraAPI else {
    print("Device does not support camera APIs")
    return
}

print(device.cameraFirmwareVersion ?? "Camera firmware version unavailable")

Objective-C

Objective-C

id<AIBudsDeviceCameraAPI> device = (id<AIBudsDeviceCameraAPI>)self.device;
if ([device conformsToProtocol:@protocol(AIBudsDeviceCameraAPI)]) {
    NSLog(@"%@", device.cameraFirmwareVersion ?: @"Camera firmware version unavailable");
}

nil का अर्थ value unavailable है; यह retry चाहने वाली operation failure नहीं।
