    Updating managed object core data

    Like saving data, we first grab the manage object context.I've been creating a project just to mess around with core data to help myself learn it, but I've come to the part of every project where I just simply can't figure this out, here it is- I am trying to create a UIAlert window, that calls the update name function I've written, that a user can enter a new name and hit update, seems easy enough, and I've got the code I need, minus one tiny piece.I will post my code, but the error I'm getting is "Cannot convert value of type 'String' to expected argument type 'Name Object'", which I understand, my Name Object class is of type NSManaged Object, I just am not sure where I went wrong or what to do.I have check the following Q&A and while the solutions are much the same the issue remains for me remains: Saving an updated Core Data instance Update/Edit core Data managed object How to update existing object in Core Data? The Core Data entity "New Log" has the following attributes When I login it creates a new object in the core data. The issue is when I logout it updates the existing object but creates a new object also.Basically you define your data model in the Xcdatamodeld file that was created with your project. NOTE: If you haven’t tried insert and fetch, please follow Core Data in i OS10 (Swift3)Step 4: Update the User into Core Data Create a function to save the data, NOTE: I have updated object at zero index only.NSPredicate can be used to find specific user, to update.It still is, but slightly differently in i OS 10 and beyond. Once that context is returned, We can move on creating Model.

    Step 1: Use Core Data Create new project, & check ‘‘. In previous i OS versions this was accessed via app Delegate.

    Thanks EDIT I know that it is creating a new object the following ways: 1.

    The SQL file displays the new object with the content stated above - logout Time and login Status 2.

    Previously, we gave you a brief introduction of Core Data and created a simple app to store all your device information.

    However, we only showed you how to insert records into data store through Core Data API and left out the update & delete operations.
