How to use Core Data with @FetchRequest in SwiftUI

How to use Core Data with @FetchRequest in SwiftUI | Continued Learning #14

3 роки тому

In this video we jump into the world of Core Data! We will first create a new Xcode project, review some of the template Core Data code that Apple provide us, and then we will customize the code for our iOS application. In this video we will implement CRUD functions by learning how to Create, Read, Update, and Delete data within Core Data. As noted in the title, this video explores how to use the @FetchRequest, which enables us to easily connect Core Data to our SwiftUI View. In the next video, however, we will learn another implementation of Core Data using MVVM architecture - that no longer uses the @FetchRequest. Both implementations are useful and good to know!

By far the best SwiftUI channel out there! You deserve a lot more subscribers!

Thank you Nick for the preface at 0:55. It clears it up that I don't need to have both an @FetchRequest variable and Core Data view model at the same time. Very neat 🤝

You just make core data easy to me ;thanks so much man

@douglasrutledge1325 2 роки тому

Thanks for your great training: My first goal is to make a 'Simple' journal app. Tag each entry with the current date:time. Save the entries automatically into CoreData. Recall entries in ScrollView based on Date. Then later automatically tag each entry with current weather:temperature; my current location during entry, then edit entries, allow for dictation, eg. as my knowledge increases.

Thanks. It is the first time that I see somebody who mark core data in the project and use it, the others remake everything

@SwiftfulThinking 3 роки тому

Yea, it's great that Apple gives us some template code but it can be hard to understand. I'm happy this helped!

Probably the best video tutorial/walkthrough I have watched, really nice to see even the standard core data code in the project really well explained, thank you. Question: Do you have a video or could you make an example of using multiple entities and also showcasing one-to-one, one-to-many etc. relations, how it works and how it can be used? /cheers

@simonbogh 2 роки тому

Well, I kept watching your videos and it seems like one on core data relationships is coming 😂 thanks mate

@thisrabbit3673 2 роки тому

A huge thanks for this series, it helps a lot! While in my trying, I wonder what are the best practices for making core data works with the preview in SwiftUI, in other words, how to preview my customized view component with different (mocked) input data (for example, a blank state, and a state with some data) if this view directly pull data from the core data database using the @FetchRequest?

Hello! love your tutorials, it's so easy to understand compared to many others I have watched. I've already started with firebase for the backend and I was wondering if you've ever thought of doing a tutorial on that? Thanks a lot!

Hi Amy! Yes, I am planning on doing a Firebase course soon. I just haven't gotten to it yet!

Thanks,.. I was so afraid to start with CoreData, because it looks so complicated for me. Believe I will understand it with You finally.

@@SwiftfulThinking Hi, I have questions :-) If You have model data (array with inserted data), can You some simply way insert it to entity in one step (structure is the same), or You have to pass array in cycle and insert each item separately? How You can delete all items in entity? Thank You

Hey men, I want to be like you when I're big!

@andresraigoza2082 2 роки тому

Thank you so much!!! 🙂 I wanted to ask you, how to decide when to use core data or remote data?

@SwiftfulThinking 2 роки тому

This is a big question but I'll try to simplify... If there is data that (1) other users need access to, or (2) you want to be saved for the current user to use across multiple devices, then you need to store it in a remote location so that other devices can access it. If it's data only for the current user on the current device, then you can save it locally. There are several options for saving locally, most common is (1) UserDefaults for small pieces of data, (2) FileManager for large data blobs, such as Images/Videos/Audio, and then (3) CoreData when you have a larger data sets that you want to save, such as data Models in your app.

Hi Nick, I found there is one miss function you didn't introduce in coreData: "move", I can add/ delete/update item, but when I want to do .onMove function, I found when I move the ForEach .onMove it will back to the original order in the entity. even I add saveData() after func move, it more badly afterI click Done it immediately back to the origin order. Can you help to have some advise, or core data cannot use .onMove function?

Im having a lot of trouble following along, there's been an update and trying to do exactly as you do the view isn't updating with the newFruit to the list. I've searched and I can't seem to find what I am doing wrong

@ushadesai6306 2 роки тому

Following Compiler error appear in the CoreData template app: 1. Generic parameter 'Content' could not be inferred' (in the ***App.swift) 2. Cannot find 'FruitEntity' in scope (in Persistence.swift and ContentView.swift) I have followed the same steps as in the tutorial.

Hey there! Is there a possibility to put the tapGesture on the entire row?

@SwiftfulThinking 3 роки тому

Hey Nico, yea you should be able to add a TapGesture to any View in Swift (you can't put it on the ForEach but you can put it on a view inside the ForEach closure).
