How to Reproduce

    let sdk = ALSdk.shared()

    if sdk.isInitialized == true {
        return

    // CCPA
    ALPrivacySettings.setDoNotSell(true)  // Set to 'true' if you want to apply "Do Not Sell"

    // Child-directed setting (COPPA)
    ALPrivacySettings.setIsAgeRestrictedUser(false) // Set to 'true' if the app is child-directed.

    // GDPR Consent
    if ALPrivacySettings.isAgeRestrictedUser() {
        ALPrivacySettings.setHasUserConsent(false)
    } else {
        ALPrivacySettings.setHasUserConsent(true)
    }

    let initConfig = ALSdkInitializationConfiguration(sdkKey: AdsConfigs.APPLOVIN_SDK_KEY) { builder in
        builder.mediationProvider = "max"
    }

    // initConfig.exce = false

    // To disable all log, enable this
    // sdk?.settings.setExtraParameterForKey("disable_all_logs", value: "true")

    // Finally, initialize the SDK
    sdk.initialize(with: initConfig) { _ in }

Hi @abinhho - thanks for raising this issue. Do you mind removing the AppLovinSdkKey from your app's Info.plist and trying again?

[abinhho]

@thomasmso Thanks for your feed back. Actually I don't have AppLovinSdkKey on Info.plist

[christophercong]

@abinhho how are you integrating our SDK? Is it through CocoaPods or SPM?

@abinhho how are you integrating our SDK? Is it through CocoaPods or SPM?

I am using CocoaPods.

[christophercong]

@abinhho can you provide your device logs and/or the stack trace?

[thomasmso]

@abinhho - If you disable exception breakpoints, does the issue still occur? I'm not saying that would be the solution, as exception breakpoints are a necessity for development, but just want to understand your issue better.

[christophercong]

@abinhho can you also confirm that you are on SDK version 12.4.0 (if you can, can you provide your Podfile.lock)? There is a log missing from the ALSdkInitializationConfiguration on init that we added.

@thomasmso

It seems app can run after disable exception breakpoints but I am not sure any issue else.

@abinhho there seems to be a mismatch somewhere here. The logs indicate 12.3.0, however the Podfile.lock indicates 12.4.0. Can you double check you have your workspace, pod, and project clean and up to date? One thing you could try is to delete your current Podfile.lock and run pod install --repo-update again.

[abinhho]

@thomasmso @christophercong Actually I tried to switch 12.3.0 and 12.4.0 but both versions are getting the same issue. That why you can see sometime 12.3.0 and sometime 12.4.0

[abinhho]

I tried

// deleted Podfile.lock
pod deintegrate
pod install --repo-update

Also tried

rm -rf "${HOME}/Library/Caches/CocoaPods"
rm -rf "`pwd`/Pods/"
pod update

Also tried

• Update MacOS to latest version
• Update CocoaPods to latest 1.15.2
• Clean build folder

One thing strange is I asked 2 co-workers trying to build on XCode 15.3 and both of them can run successfully. Only me getting this issue.

[abinhho]

@abinhho can you also confirm that you are on SDK version 12.4.0 (if you can, can you provide your Podfile.lock)? There is a log missing from the ALSdkInitializationConfiguration on init that we added.

I tried to delete XCode and install new one but not resolve the issue. Log of ALSdkInitializationConfiguration here but still getting crash.

[abinhho]

@thomasmso @christophercong After removed directory MyApp.xcodeproj/xcuserdata and MyApp.xcworkspace/xcuserdata then it works now. I guess AppLovinSdkKey stored there but I am not sure.

Thank you all for your time.
