Can anyone point me in the right direction to resolve this?

};
},

@bosunolanrewaju No! Still got to try to work out what to do, have inherited an app from someone, this is quite a blocker... maybe have to rip some things out and work back up...
@chrisbarry Looks like I found a fix for our issue.
See this here from https://github.com/oblador/react-native-keychain/blob/master/RNKeychainManager/RNKeychainManager.m#L354-L359:
NSDictionary *attributes = attributes = @{
(__bridge NSString *)kSecClass: (__bridge id)(kSecClassGenericPassword),
(__bridge NSString *)kSecAttrService: service,
(__bridge NSString *)kSecAttrAccount: username,
(__bridge NSString *)kSecValueData: [password dataUsingEncoding:NSUTF8StringEncoding]
};
The error says it is attempting to pass nil at index[3], which means the password being passed is null. Ensure that the password is not null. In our case, the value was null. Setting it to an empty string fixed it for us.
It is also mentioned in the readme file below the Usage section here that the values are limited to strings only. https://github.com/oblador/react-native-keychain#usage
HTH.
Hi @chrisbarry I have the same problem. v. 7.0.0 very basic setup, iOs, RN 0.64
@chrisbarry for me the problem resolves after adding capabilities in Xcode, see here:
https://github.com/oblador/react-native-keychain#enable-keychain-sharing-entitlement-for-ios-10
In my case the issues was that I was trying to store on object Make sure you only pass strings
