Learn to display images in an image view with Xcode, import and copy images, use aspect fit or aspect fill, and connect outlets and actions in a view controller.

Explore how Swift dictionaries use key-value pairs to store and retrieve data, unlike arrays where order matters. See examples with dog names and ages to illustrate retrieval by key.

Explore how to update, add, and remove entries in Swift dictionaries, enforce key and value types, ensure unique keys, and work with dictionary literals in practical examples.

Create a core data entity game with title and image attributes, enable external image storage, convert UI images to data, and save via a managed object context.

Learn to fetch game objects from Core Data, populate a table view, and display images in each cell by decoding NS data into UIImages, with a reload after adding items.

Learn to commit changes, manage game objects with core data, and reuse a single view controller for add, update, and delete actions using segues and conditional user interface.

Manage add and update with a single action, edit existing core data objects, save changes, and implement delete with context, save, and view popping.

Learn to use image views and UI images, fetch photos from the library or camera, store images in Core Data, and implement an optional-based update delete flow for games.

Build a soundboard app using the microphone to record noises with names, display them on screen, tap to play, and learn Swift air handling with swipe-to-delete in a table view.

Build a soundboard app with a table view and plus button to add sounds. Record, stop, and play sounds, validate input, and enable swipe-to-delete with core data in Xcode.

Set up the user interface by building a plus button, navigation flow, and input controls in the storyboard, wiring outlets and actions to save items and display in a list.

Set up AVFoundation to record audio on iOS by creating an AVAudioRecorder with a URL and settings, and configure an audio session for play and record.

Learn how to handle errors in Swift by marking functions with throws, using try, and wrapping calls in do-catch blocks with catch to respond to and get details about failures.

Create the documents directory path, build the audio file URL, and configure the settings dictionary with format, sample rate, and channels to prepare the audio recorder.

Tap the record button to start and stop recording via the microphone, toggling the button title between stop and record, using the audio recorder's isRecording property to control flow.

Save a recorded sound by creating a Core Data entity named sound with a name and binary audio data, converting the file URL to data, and saving via the context.

Fetch and display saved sounds in a table view using core data, populate cells with sound names, and play a selected sound with AVFoundation’s AVAudioPlayer.

Implement a swipe left to delete in a table view using the commit editing style, delete from core data, and refresh the list.

Explore audio by recording and playing sounds, learn basic air handling concepts, and see how a soundboard app evolves toward uploading to the app store.

Learn to generate and manage certificates by manually creating a certificate signing request with keychain access, submitting to a certificate authority, and downloading the distribution certificate for iOS development.

Create a new app identifier with a reverse domain style prefix, name it coloristic, choose a wildcard app ID, submit to register, and prepare provisioning profiles.

Generate and download the provisioning profile by pairing the distribution certificate with your App ID for an App Store release, then move on to iTunes Connect.
