Create App Like Instagram using Parse Server: iOS 11 Swift 4

Create a PFObject for the 'people' class, set first name, last name, and age, and save the record to the Parse server in the background.

configure app transport security to allow arbitrary loads, enabling http connections in an ios 11 swift 4 project and observe database records updated via parse server.

Set up the Parse dashboard to manage app data with a browser interface, installing node and npm, configuring app id, master key, and app name, and running locally at localhost:4400.

Learn to retrieve the first object that matches a query from the cloud database using a background operation, and understand how default ordering affects which item is returned.

Delete a PFObject from the database by retrieving the object and calling deleteInBackground. Use deleteInBackground with a block to know when the deletion completes.

Learn to use the where clause to filter Parse Server queries, applying conditions like age less than 50 or less than or equal to 50 and retrieving specific results.

Count objects in the background instead of fetching full records. Retrieve an integer result, handle errors, and learn to use convenience methods to avoid expensive queries.

Master managing Parse dashboard data by adding a new row with required fields, including an address column, and creating or deleting columns, classes, and records.

Design the home screen and post screen for a mini Twitter app by embedding in a navigation controller, implementing a table view with reusable cells, and wiring like and comments.

Design the login storyboard by creating login and register screens with username and password fields, adding login and register buttons, and setting the login screen as the entry point.

Check PFUser login status in the app delegate and route to home or login screens using storyboard identifiers and the window root view controller.

Create registration and login screens, connect outlets and actions, and implement register and close actions to wire the UI to your app.

Learn to build a singleton helper class to centralize navigation and alert presentation, enabling easy switch between login and home screens and reducing code duplication in iOS apps.

Set up the post view by creating a post file, wiring outlets and actions for the message field and post button, and validating content before posting.

Validate that the message text is not empty before posting. Create a new Parse message object with sender, text, likes, comments, and flag count, then save in background and confirm.

Fetch all messages from the backend and display them in a table view by implementing the data source methods and a background PFQuery to refresh the table.

Wire up like and comment buttons in a Swift 4 iOS app by tagging cells, using selectors, and implementing likeClicked and commentClicked to identify the tapped row.

Design the comments screen UI in interface builder with a text field, a post button, and table view for comments. Configure segues and a navigation bar using the comments identifier.

Identify and pass the selected object to the comments screen by preparing for segue, casting the destination view controller, and assigning an optional PFObject called selectedObject.

Display comments retrieved from the backend on the comment screen. Bind a string array of comments to the table view data source and render each in a cell.

Refresh backend data when returning to the home screen to update the comments. Move update logic from the deep load to the correct place to ensure UI reflects changes.

Parse dashboard errors occur when port 4040 is occupied by another session, especially with two accounts. Terminate running services and relaunch after switching accounts.

Explore a starter project called the family album to upload a photo with a description, post it, and view photos and captions in a table view.

Discover another way to enable anonymous users with a background login using a block that creates a backend user and assigns a username.

Create a Parse custom class by subclassing PFObject, define optional message, PFFile image, and PFUser current user properties, and save posts to the backend.

Learn how pointers reference related objects, and how include key queries fetch user data in a Parse Server powered Instagram-like app.

Add a profile screen and integrate the Parse UI library to select and display a photo with the IPF image view, wiring an image picker and testing the image display.

Attach the Parse file to a PFImageView and load it in the background to display the current user's profile image efficiently.
