Explore how to design a cohesive launch screen in Xcode using a storyboard, matching the app theme with the icon, image, and label through constraints.

Learn how the plist.info file customizes your app name and identifier, sets device orientation and launch screen, and ensures the app exits on suspend rather than running in the background.

discover how to change the status bar color in an iOS app by switching to light content, acknowledging black navigation bars, and enabling controller based status bar appearance.

Learn how to hide the status bar in an app, toggle visibility, and understand default settings and color changes when the option is enabled, noting the required key.

Learn to use flaticon.com to download icons for your app, select colors, download a PNG, and verify proper licensing for the app icon.

Create a 1024 by 1024 app icon in Canva.com by uploading your image, centering it, choosing a background, and exporting the final icon for the app.

Explore how to generate app icons at the correct sizes using the asset catalogue tool, including iPhone and iPad variants, universal apps, and splash/launch screen assets.

Drag the icon from the icons folder into Xcode, copy items, and set it as the app icon in the target. Run the app to see the icon applied.

Learn how to resolve common build time and runtime issues in an iOS app, such as unreachable controllers, missing entry points, and deprecated push segues, aiming for zero issues.

Learn to debug view hierarchy by using the debug view to inspect a running app, explore layers, constraints, and memory addresses to understand layout.

Monitor your app’s memory usage in the simulator, observe how images and UI elements increase memory, and keep usage steady to prevent crashes on devices with limited RAM.

Explore how memory usage spikes as views load, learn to simulate memory warnings in the Xcode simulator, and dispose resources to free memory when the app needs it.

Learn how the app delegate handles lifecycle events—from launch to foreground, background, and termination—by wiring delegate methods that print status and manage resources.

Understand the view controller entry point and how viewDidLoad loads views into memory, then use viewWillAppear and viewDidAppear for UI updates and animations.

Explore the Apple documentation class reference to understand ui elements like labels and image views, and learn key properties such as text, color, font, and text alignment.

Master the iOS coordinate system, where views use x, y, width, and height with (0,0) at the top-left. Learn to place views using Interface Builder's size inspector.

Learn to add a UILabel programmatically to a view without interface builder, using frame coordinates and addSubview, then customize text, color, font, and alignment.

Programmatically add a UIImageView and access class definitions in Xcode, set its frame, assign an image, configure content mode and centering to display the image.

Learn how to create IBOutlets and reference Interface Builder elements, connect them to code, and manipulate properties like text and background color to build responsive iOS interfaces.

Learn to create and connect view controller swift files for additional scenes, set the controller class in identity inspector, and wire up multiple files for a storyboard-driven iOS app.

Learn to create IBActions for UIButton clicks, connect actions with touch up inside, name actions clearly, and test button presses by printing results for Facebook and YouTube.

Learn how to recover from an outlet connection error by deleting the mistaken outlet, removing the stale storyboard reference, and reestablishing a correct outlet connection so your app runs again.

Learn to dynamically update a view’s text with button actions by swapping the top level label and info text for social media, and adjusting font size to fit.

Enable a large title in the navigation bar by configuring the navigation controller and setting the large title preference to true, then preview the home screen.

Disable the large title on a view controller by configuring the navigation bar's large title display mode to never. This ensures a distraction-free second screen in a two-screen flow.

Learn to quickly adjust font size in the app by using the command key with plus or minus, replacing the old multi-step method of selecting text and changing size.

Run multiple simulators at the same time to compare app behavior and design across devices, view side-by-side layouts, and test different screen sizes.

Explore how iOS simulators now emulate hardware buttons—power, mute, and volume controls—allowing lock, unlock, and quick access to the home screen without relying on on-screen shortcuts.
