How can I correctly identify my Fitbit peripheral using Core Bluetooth in iOS?

I'm using Core Bluetooth in my iOS project to discover peripherals and I want to filter out my Fitbit device using its UUID. I've written the following code:

SWIFTCopied
func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) {
    guard peripheral.identifier != UUID(uuidString: "FEFEA0F0-90D3-BB0A-7732-12ADAB579D77") else {
        return
    }

    print("Discovered peripheral: \(peripheral.identifier)")
}

When I run the app, the debug window shows several discovered peripherals, for example:

BASHCopied
Discovered peripheral: 49AB5D83-1F40-0B71-9DD0-E51E60AD4BD4
Discovered peripheral: FE0BF3FD-9BCC-B016-A386-ACD063B70927
Discovered peripheral: 42270FB6-518C-EEF2-909A-6B2D77B2F0CF
Discovered peripheral: 49AB5D83-1F40-0B71-9DD0-E51E60AD4BD4
Discovered peripheral: C12736EB-B976-ACAB-BC6F-56FDA73CC7F1
Message from debugger: killed

I understand that the "Message from debugger: killed" line is from LLDB when the process is terminated (likely by manual stop or runtime conditions) and not an error in the delegate method. My main concern is whether I'm correctly identifying my Fitbit device, as the log shows different UUIDs. How can I reliably determine which peripheral is my Fitbit? What is the best practice for filtering and identifying a specific device using Core Bluetooth?
