Undefined symbol: _OBJC_CLASS_$_ADClient

  • (void)asaAttribution { if (@available(iOS 14.5, *)) { [self asaAttributionToken]; NSLog(@"adServicesToken1:%@",[ConfigModelTool singleton].asaToken); [self attributionWithToken:[ConfigModelTool singleton].asaToken]; }else { if ([[ADClient sharedClient] respondsToSelector:@selector(requestAttributionDetailsWithBlock:)]) { [[ADClient sharedClient] requestAttributionDetailsWithBlock:^(NSDictionary<NSString *,NSObject *> * _Nullable attributionDetails, NSError * _Nullable error) { if (!error) { [self handleAsaData:attributionDetails]; }else { [StatisticsTool buriedPoint:4649 withOther:@{@"s0":[NSString checkNullString:[NSString stringWithFormat:@"%d",(int)error.code]]}]; } }]; } }

} I upgraded the code that was compiled correctly before the official version of Xcode16, but now this error occurs. I deleted the relevant code and still compile the error. My writing style is recommended by the installation official. Can someone help me see what the reason is? Save me, save me!
