UnityAds folder in ios build without having the advertisement package

We need to make sure that we have not tracking or ads in our app for iOS since we it is for kids. But we got rejected multiple time for exactly that reason form Apple. After some digging i found that every build we created a UnityAds folder gets added in (Project/Classes) as well as a file DeviceSettings.mm, which links the /System/Library/Frameworks/AdSupport.framework and #include<AdSupport/ASIdentifierManager.h> Apple pointed out to us that we need to remove both if we want to complaint with their guidlines.
To make sure it is not the issues of a plugin i create a fresh project made sure no services or advertisement package as included/installed. With the same result!

I tried deleting the files with gave a me errors for xcode while compiling.
Is there a way to remove that completely ?

 

Which Unity version?

 

i am on 2019.3.1f1

 

Yes, also managed to reproduce issue in 2019.3.1f1 here. After building a empty project without Ads enabled, would have following files in the generated Xcode project:

Code (CSharp):

1. $ find . | grep UnityAds
2. ./Builds/iOS/Classes/UnityAds
3. ./Builds/iOS/Classes/UnityAds/UnityAdsConfig.h
4. ./Builds/iOS/Classes/UnityAds/UnityAdsUnityWrapper.mm

However, when deleting the Classes/UnityAds folder from within xcode, then I was able to compile project without problems. What error are you getting in that case?

Apple Clang Error:

 

Showing Recent Issues
No such file or directory: '/Desktop/Unity/build Test/test for fw 6/Classes/UnityAds/UnityAdsUnityWrapper.mm'

 

Did you remove the folder from within Xcode, or just from command line?

 

I removed it from the finder, i will try from xcode and comand line as well

 

Removing it from Xcode seems to solve it! Will there be a fix for that or will the solution be to always remove it before building?

 

samge goes for the DeviceSettings.mm file (also in the Classes folder) with the following problemetic code snippets:

Code (CSharp):

1. #include <sys/types.h>
2. #include <sys/sysctl.h>
3.  
4. #include <AdSupport/ASIdentifierManager.h>
5.  
6. #include "DisplayManager.h"

13.     if (bundle)
14.     {
15.         [bundle load];
16.         Class retClass = [bundle classNamed: @"ASIdentifierManager"];
17.         return [retClass performSelector: @selector(sharedManager)];
18.     }
19.  
20.     return nil;
21. }
22.  
23. extern "C" const char* UnityAdvertisingIdentifier()
24. {
25.     static const char* _ADID = NULL;
26.     static const NSString* _ADIDNSString = nil;
27.  
28.     // ad id can be reset during app lifetime
29.     id manager = QueryASIdentifierManager();
30.     if (manager)
31.     {
32.         NSString* adid = [[manager performSelector: @selector(advertisingIdentifier)] UUIDString];
33.         // Do stuff to avoid UTF8String leaks. We still leak if ADID changes, but that shouldn't happen too often.
34.         if (![_ADIDNSString isEqualToString: adid])
35.         {
36.             _ADIDNSString = adid;
37.             free((void*)_ADID);
38.             _ADID = AllocCString(adid);
39.         }
40.     }
41.  
42.     return _ADID;
43. }
44.  
45. extern "C" int UnityGetLowPowerModeEnabled()
46. {
47.     return [[NSProcessInfo processInfo] isLowPowerModeEnabled] ? 1 : 0;
48. }
49.  
50. extern "C" int UnityGetWantsSoftwareDimming()

61. {
62. #if !PLATFORM_TVOS
63.     UIScreen* mainScreen = [UIScreen mainScreen];
64.     mainScreen.wantsSoftwareDimming = enabled;
65. #endif
66. }
67.  
68. extern "C" int UnityAdvertisingTrackingEnabled()
69. {
70.     bool _AdTrackingEnabled = false;
71.  
72.     // ad tracking can be changed during app lifetime
73.     id manager = QueryASIdentifierManager();
74.     if (manager)
75.         _AdTrackingEnabled = [manager performSelector: @selector(isAdvertisingTrackingEnabled)];
76.  
77.     return _AdTrackingEnabled ? 1 : 0;

Since apple gave us this as problematic code for our rejection: WE also noticed that your kids app collects, transmits, or has the ability to share personal information or device information. Specifically, the app includes Unity SDK with dynamic use of the Ad Support framework including +[NSBundle bundleWithPath:] and -[NSBundle classNamed:] for strings "/System/Library/Frameworks/AdSupport.framework" and "ASIdentifierManager" as well as access the advertisingIdentifier. To resolve this issue, please revise your app so that no personally identifiable information or device information is sent to third parties.

 

Thanks for reporting. Yes, we have recently became aware of this change to Apple guidelines, and we are working actively on solving it.

Hey Rasmus, has this been resolved in the latest version of Unity? I'm running into the same issue.
