Swift 4.2 to 5.0 upgrade

Hi,

We used KeychainAccess to store our encryption key in keychain. We encountered bug when upgrading our application Swift version from 4.2 to 5.0 the key dissapeared from keychain.

        let keychain = Keychain(service: serviceId)
        
        var key = Data(count: 64)
            _ = key.withUnsafeMutableBytes { bytes in
                SecRandomCopyBytes(kSecRandomDefault, 64, bytes)
            }
        try? keychain.set(key, key: keyId)
