Thread Network API not working

I'm trying to use ThreadNetwork API to manage TheradNetworks on device (following this documentation: https://developer.apple.com/documentation/threadnetwork/), but while some functions on THClient work (such as getPreferedNetwork), most don't (storeCredentials, retrieveAllCredentials). When calling these functions I get the following warning/error:

Client: -[THClient getConnectionEntitlementValidity]_block_invoke - Error:

-[THClient storeCredentialsForBorderAgent:activeOperationalDataSet:completion:]_block_invoke:701: - Error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service with pid 414 named com.apple.ThreadNetwork.xpc was invalidated from this process." UserInfo={NSDebugDescription=The connection to service with pid 414 named com.apple.ThreadNetwork.xpc was invalidated from this process.}

Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service with pid 414 named com.apple.ThreadNetwork.xpc was invalidated from this process." UserInfo={NSDebugDescription=The connection to service with pid 414 named com.apple.ThreadNetwork.xpc was invalidated from this process.}

Failed to store Thread credentials: Couldn’t communicate with a helper application.

STEPS TO REPRODUCE

1. Create new project

2. Add Thread Network capability via Xcode UI (com.apple.developer.networking.manage-thread-network-credentials)

3. Trigger storeCredentials

let extendedMacData = "9483C451DC3E".hexadecimal

let tlvHex = "0e080000000000010000000300001035060004001fffe002083c66f0dc9ef53f1c0708fdb360c72874da9905104094dce45388fd3d3426e992cbf0697b030d474c2d5332302d6e65773030310102250b04106c9f919a4da9b213764fc83f849381080c0402a0f7f8".hexadecimal

// Initialize the THClient

let thClient = THClient()

// Store the credentials

await thClient.storeCredentials(forBorderAgent: extendedMacData!, activeOperationalDataSet: tlvHex!) { error in

if let error = error {

print(error)

print("Failed to store Thread credentials: \(error.localizedDescription)")

} else {

print("Successfully stored Thread credentials")

}

}

NOTES:

• I tried with first calling getPreferedNetwork to initiate network permission dialog

• Tried adding meshcop to bojur services

• Tried with different release and debug build configurations
