Hello ,

As I am trying to connect with local relativity server on my system from xcode with DARemoteDataAdapter , Please find the code snippet

rda = DARemoteDataAdapter(targetURL: URL(string: "http://localhost:7099/bin")!)
rda.username = "Administrator"

 @objc func remoteDataAdapterNeedsLogin(_ adapter: DARemoteDataAdapter) -> Bool {
        return rda.login(withUsername: "my user name", password: "password", connectionName: "Tasks")


    }

Here . in connectionName i have provided my schemas name.

In the below function I am geeting exception error
@objc func remoteDataAdapter(_ adapter: DARemoteDataAdapter, requestDidFailWith exception: NSException) {

//Error comes :- ################################

An exception occurred on the server: BinMessage: Unexpected end of stream.

Hello

Seems you’re using wrong rda.login method.

The one you have to use to logi in to Relativity is

- (BOOL) loginWithString:(nonnull NSString*)loginString ;

Login String parameter expected here conceptually is very close to database connection strings. For Relativity Server it can be composed as

NSString *loginString = [NSString stringWithFormat:@"User=%@;Password=%@;Domain=%@;Schema=%@",
                         userName, password, domain, schema];

Hope that helps

Thanks Antonk,
For the quick reply, I tried the same here is my code snippet:-

rda = DARemoteDataAdapter(targetURL: URL(string: “http://172.16.6.71:7099/bin”)!)
super.init()

    rda.delegate = self
    rda.username = "Administrator"
    rda.password = "Relativity"  //Administrator

@objc func remoteDataAdapterNeedsLogin(_ adapter: DARemoteDataAdapter) → Bool {
// NSString *loginString = [NSString stringWithFormat:@“User=%@;Password=%@;Domain=%@;Schema=%@”,userName, password, domain, schema];
return rda.login(with: “User=Alex;Password=111;Domain=DATutorial;Schema=Tasks”)
}

I am getting the same error again. Can you please see what else I am missing.

rda.login;

and

rda.loginWithString: aConnectionString ;

are completely different methods.

You need to either call correct method in remoteDataAdapterNeedsLogin OR to replace

    rda.username = "Administrator"
    rda.password = "Relativity"  //Administrator

with

    rda.loginString =  “User=Alex;Password=111;Domain=DATutorial;Schema=Tasks”

and call the rda.login; method

Thanks Antonk,
For your help. This solution is working correctly.

For the record, though:

rda.login(with: is loginWithString. Welcome to Swift’s mangling of ObjC’s beautiful APIs :wink:
