Hey @virtualblessing

Thanks for using the dev forum!

Normally this happens because Xcode cannot find the framework at run time.

Make sure you select “Embed and Sign” next to MobileRTC.framework in the “Frameworks, Libraries, and Embedded Content” section of MobileRTCSample -> General.

If the problem persists with these settings, let me know and we can debug together :slight_smile:


Thanks It’s work. but i have another issue while auth verification.
issue : “reason: '* -[NSBundle initWithURL:]: nil URL argument’**”
My code : let mainSDK = MobileRTCSDKInitContext()

mainSDK.domain = “


let authService = MobileRTC.shared().getAuthService()


authService?.delegate = self

authService?.clientKey = “sdkKey”

authService?.clientSecret = “sdkSecret”


I downloaded swift demo app form GitHub Link ( I run both demo app objectC and swift i got this errors

Hey @virtualblessing

For your first question, I do not advice using optionals for the initialization process. A race condition is possible when not unwrapping during the initialization process. Instead, you should do the following:

    let context = MobileRTCSDKInitContext()
    context.domain = ""
    context.enableLog = true

    let sdkInitializedSuccessfully = MobileRTC.shared().initialize(context)

    if sdkInitializedSuccessfully == true, let authorizationService = MobileRTC.shared().getAuthService() {
        authorizationService.clientKey = sdkKey
        authorizationService.clientSecret = sdkSecret

        authorizationService.delegate = self

For your second error: Did you modify anything within the repo before running? You should be able to clone the repo and run either project without modification. Usually, when those errors happen, the framework is not embedded correctly or is expected to be in a different location.
