Realm is not created on the first launch

[max-zu]

App crashes on the first launch after update from 2.2.10 to 2.28.0.
On the second launch app works fine.

react-native: 0.55.4
macOS: 10.14.5

POST http://192.168.42.36:8083/create_realm net::ERR_EMPTY_RESPONSE.

It seems that condition on this line is incorrect.

I am seeing iOS crashes on createDirectoryAtPath.

    "react": "^16.8.6",
    "react-native": "0.59.9",
    "realm": "^2.28.1",

Adding the missing not sign "!" fixes.

        NSError *error = nil;
        if (![manager createDirectoryAtPath:docsDir withIntermediateDirectories:YES attributes:nil error:&error]) {
            throw std::runtime_error(util::format("Failed to create directory \"%1\": %2", docsDir.UTF8String, error_description(error).UTF8String));
        }
