Googleads-mobile-unity: Cannot find protocol declaration for 'GADRewardedAdDelegate'; did you mean 'GADNativeAdDelegate'?

[ugurdeniz20]

I am getting 10 errors like this. Only from 'GADRewardedAd' library.
on XCode 12.4

[Fudds]

Having this same problem on the most recent Google Mobile Ads plugin for iOS. Mediating through ironsource

[ugurdeniz20]

Doesn't have any solution?

[riocallos]

Using Unity 2018.4.34f1, XCode 12.5, and Google Mobile Ads Unity Plugin v6.0.0. I am getting this exact same issue. https://github.com/googleads/googleads-mobile-unity/issues/1569 is a similar issue raised here last February it was closed but it still isn't fixed. These are the 10 issues shown in xcode when building

[olpero]

@riocallos I had those same errors before I deleted the old files from the previous version of admob. But after that I get "Undefined symbol" errors when building with xcode.

[hlongvu]

Face this issue too, turn out because updating the plugin without delete old file at Plugins/iOS

[antonysze]

I tried to remove all old files in Plugins/iOS from the last version, it still shows the same error on my Xcode.
I have also tried importing source code from 6.0.0 tag instead of release unity package, which doesn't work either.

Unity 2019.4.18
Google Mobile Ads Unity Plugin v6.0.0
Xcode 12.4

[riocallos]

It is now somehow fixed on my side. I'm not really sure how it was fixed but I just ran pod install and then opened the xcworkspace then it was all good.

What version Unity you used?

@thaothao0501 Unity 2018.4.34f1, XCode 12.5

[minidragon-jacky]

Facing the same problem here. I am using Unity 2019.4.21f1 and XCode 12.4.
I just found that GoogleMobileAdsDependencies sets the version of "Google-Mobile-Ads-SDK" as ~> 7.50.
However, IronSource AdMob Adapter requires "Google-Mobile-Ads-SDK" for version >= 8.50.
So I editor GoogleMobileAdsDependencies .cs form ~> 7.50 to => 7.50
And I just found that GADRewardedAdDelegate is only for version 7.X
So when cocoapod install version 8.50 in my project. GADRewardedAdDelegate will be missing.
I don't know how to solve it instead of waiting for official update.

[wwidelec1]

Changing my ads pods to:

pod 'GoogleMobileAdsMediationAppLovin', '6.14.6.0'
pod 'GoogleMobileAdsMediationFacebook', '6.2.0.0'
pod 'GoogleMobileAdsMediationUnity', '3.5.0.0'
pod 'Google-Mobile-Ads-SDK', '7.69'

Helped with this error, but instead i got:

Plugins/iOS/UnityAdsShowListener.h:8:45: No type or protocol named 'UnityAdsShowDelegate'
Plugins/iOS/UnityAdsUnityWrapper.m:79:15: No known class method for selector 'show:placementId:showDelegate:'

I guess it was related to what I changed. It's so frustrating.
Did someone manage to solve it?

[wwidelec1]

Update: Deleting all mediations and setting 'Google-Mobile-Ads-SDK' to 7.69 fixed it, i can build the game. But it crashes on splash screen

[erikhallgren]

I'm having this issue as well, severly blocked by it
I run no mediation

'Google-Mobile-Ads-SDK', '~>8.2'
Leads to:

• Undefined symbol: _GADURequestInterstitial

'Google-Mobile-Ads-SDK', '7.69.0'
Leads to:

• Undefined symbol: _GADURequestInterstitial
• Undefined symbol: _OBJC_CLASS_$_GADInterstitialAd

[erikhallgren]

Update: Deleting all mediations and setting 'Google-Mobile-Ads-SDK' to 7.69 fixed it, i can build the game. But it crashes on splash screen

Check that error message, it probably is because of no SKAdNetwork identifier in your .plist

[wwidelec1]

@erikhallgren "Undefined symbol" is totally different error. I'm not an iOS expert, but as far as i remember, changing architectures, or adding -objC to linker flag might help with this.

[wwidelec1]

Hey @riocallos, can you send us your podfile and podfile.lock? Or type "cat Podfile.lock" in your project's location in terminal and send us the logs. It will be really helpful

Still broken on Admob Unity Plugin v6.0.1. Will you fix it or?

[wwidelec1]

I deleted everything under Plugins/iOS, then updated admob and it works now. I got another error, but it was easy to fix with google

Is that "another error" about 'GADUAdNetworkExtras.h' file not found? Ref:
https://github.com/googleads/googleads-mobile-unity/issues/1617
https://github.com/googleads/googleads-mobile-unity/issues/1552

[wwidelec1]

@p0w1nd Nope, it was different. I don't remember the content, but I was albe to fix it in 5 minutes with google :)

[williamtong0228]

I also have the problem
Plugins/iOS/UnityAdsShowListener.h:8:45: No type or protocol named 'UnityAdsShowDelegate'
Plugins/iOS/UnityAdsUnityWrapper.m:79:15: No known class method for selector 'show:placementId:showDelegate:'

It could be that I updated from verified 3.6 to 3.7.1 , but later when I removed both and reinstall 3.6, it told me that it cannot find ibraries/com.unity.ads/Plugins/iOS/UnityAdsShowListener.mm in the target.
So frustrated, I really want to go without unityads, the website asked me to update to 3.7.x where it cannot be complied or with empty reference.

Please check if this solves your issue: https://github.com/googleads/googleads-mobile-unity/issues/1569#issuecomment-874685709

[OmarMahmoud120]

I fix it by removing the ads SDK from the project totally and import it again
