Non-public symbol ___kCFBooleanTrue

My app binary is getting rejected for non-public symbol ___kCFBooleanTrue. This occurred after updating the deployment target from 12 to 13 without any significant code changes. Searching my pods I see FBSDKKeychainStore uses

Code Block  [query setObject:(id)kCFBooleanTrue forKey:[FBSDKDynamicFrameworkLoader loadkSecReturnData]];

Code Block
[query setObject:(id)kCFBooleanTrue forKey:[FBSDKDynamicFrameworkLoader loadkSecReturnData]];

and PFKeychainStore has

Code Block query[(bridge NSString *)kSecReturnData] = (bridge id)kCFBooleanTrue;

Code Block
query[(bridge NSString *)kSecReturnData] = (bridge id)kCFBooleanTrue;

Neither of these lines are new. Any idea why my app is now being rejected?
