Updated Constants.java correctly, build and runs fine.

Then, attempt to login with a nickname

Expected Results

Expected to login successfully

Actual Results

SyncUser.logInAsync throws an error to the client

Stacktrace showed it was returning an empty header, so I checked the Constants file and realized it was trying to access the cloud via http instead of https which couldn't be right, so I made the change and that fixed it.

Code Sample

Changed this line in Constants.java from...

public static final String AUTH_URL = "http://" + INSTANCE_ADDRESS + "/auth";

to...

public static final String AUTH_URL = "https://" + INSTANCE_ADDRESS + "/auth";

Version of Realm and tooling

Realm version(s): Cloud / Realm Platform / Realm Sync

Android Studio / XCode version: 3.2.1

Which device OS version and device: Mac 10.13/6

I had to change my constants file to look like the following for it to work with on-prem ROS:

struct Constants {
    // ****
    // **** Replace the "MY_INSTANCE_ADDRESS" here with the hostname of your
    // **** Realm Cloud instance or the URL of your on-premises Realm Object Server
    // ****
    
    static let AUTH_URL = URL(string: "http://127.0.0.1:9080")!
    
    static var REALM_URL: URL {
        let realmsUrlString = Constants.AUTH_URL.absoluteString.replacingOccurrences(of: "http://", with: "realm://")
        return URL(string: "\(realmsUrlString)/ToDo")!
    }
    
}```

Having the same Realm schema on iOS & Android will allow cross binding tests.

• Make sure the model matches in all tutorials
• Test that each tutorial work across binding

Suggestion - it occured to me that cancelling out of the login panel on Welcome screen results in a blank screen on the Android version with no way to get the panel back up.

It was the same on the iOS version; there's really no other activity possible in that mode, so I removed the cancel button so the user always has the login panel up if they're not logged in.

• Use objectPermission tutorial
• Login and start syncing some tasks
• Open Realm Studio to observe changes to the reference Realm
• Logout from the app
• Login with the previous user
• Modifications are not uploaded, same for changes operated by Studio are not downloaded

Expected Results

Ability to login using SyncCredentials.usernamePassword

Actual Results

Thread 1: Fatal error: The provided credentials are invalid or the user does not exist.

Steps & Code to Reproduce

Describe your current debugging efforts.

Code Sample

I replace the call to
let creds = SyncCredentials.nickname(username, isAdmin: true)
with
let creds = SyncCredentials.usernamePassword(username: username, password: username, register: true)

Version of Realm and tooling

Realm version(s): ? 3.5.0
Realm Cloud

Android Studio / XCode version: ? Xcode 9.3

Which device OS version and device: ? iOS 11 Simulator

Within the constants file:

// **** ROS On-Premises Users
// **** Replace the AUTH_URL string with the fully qualified address of your ROS server, e.g.:
// **** "http://127.0.0.1:9080" and "realm://127.0.0.1:9080"

Should really read:

// **** ROS On-Premises Users
// **** Replace the MY_INSTANCE_ADDRESS string with the fully qualified address of your ROS server, e.g.:
// **** "http://127.0.0.1:9080" 

Expected Results

Be able to see todo list items synced from the cloud instance

Actual Results

No items at all

Steps & Code to Reproduce

• I've download the example files for iOS (02-full-sync in specific), installed the pod and created a new Cloud Instance
• I updated Constants.swift with the correct value in the MY_INSTANCE_ADDRESS let.
• Opened Realm Studio and created a new realm ("ToDo") in that instance.
• Then I run the app in the simulator
• Register a new user
• Add a todo item

Untill this point it seems to work correctly, but if I open Realm Studio, and the ToDo realm in particular, it displays:

This Realm has no classes defined

And after that if I remove the app from my simulator's springboard en re-run it.
After logging in, with the same user, my previously created todo item is gone.

I would expect it to be there, since it should be stored in the cloud, but it's not.
In Realm Studio I do see the newly registered user.

Code Sample

objectPermission is still registering an async query & wait for the UPDATE state as a signal that the permission schema has been synchronised from the server. This could be avoided by using an asyncOpen that starts with a schema-less Realm then waitForChange (similar to what Cocoa is doing).

This should be fixed once realm/realm-java#5812 is implemented

This issue discusses the design of the ObjectLevelPermission tutorial, once it's available for the bindings.

we could use this type of permission configuration https://github.com/realm/realm-sync/pull/1868/files#diff-0e3567aa4be9697779a43bc487abdcf9R441 which should allow creating a normal class where users can modify their objects, but not necessarily see objects of other users.

It the context of the ToDo app this could be translated into restricting access into the Project class, so only the owner can see it & modify it. I think it's a nice transition from the PartialSync demo where everyone can still query for others Project and edit them

WDYT @dhmspector @bigfish24 ?

Steps & Code to Reproduce

Login with a nickname
Uninstall / Reinstall the app
Login with the same nickname

 public func permissions(forClassNamed className: String) -> List<Permission> {

        return classPermission.permissions
    }
Thread 1: Fatal error: Unexpectedly found nil while unwrapping an Optional value

Also, 3 permissions are added and a new partial path with the same user

The iOS tutorial calls for adding some new files to a clone of this project (eg. here) and doing this generates a template copyright header at the top of the new file. But the auto copyright is going to "Maximilian Alexander" which I believe is incorrect for new files, and may confuse people. I suggest removing this name from the Xcode project metadata entirely or changing it to "Realm"
