Learn iOS Programming Building a To-Do Utility App

Master laying out a to-do app by configuring a stack view to fill the view, applying height and width constraints, and adjusting margins and priorities across devices.

Refine the main UI in a to-do app by adjusting constraints, adding left and right margins, and aligning stacked views and table heights for a polished, consistent layout.

Apply spacing and color tweaks in an iOS to-do app by converting the stack to horizontal, adding constrained labels, adjusting inter-item spacing, and refining typography with San Francisco and grays.

Color the navigation bar in a to-do app by adding a new view controller, setting the tint color with rgb values in Interface Builder, and styling the bar text.

Learn to build the add view UI for a to-do app on iOS, integrating a date picker, text field, delegates, and Core Data setup.

Add a bottom table view with a prototype cell that includes a checkbox and a to do item description label, wire outlets and constraints, and prepare for core data integration.

Define a to-do entity with due date and complete attributes and create a core data manager. Add fetch, save, and update functions with an optional predicate for data retrieval.

Save data with a core data workflow by creating a to-do object in a managed object context, setting complete, due date, and item, and handling save errors.

Retrieve data from Core Data to populate the to-do list, refreshing on view will appear with a predicate filtering due dates within five days.

Build and configure table view cells for a to-do app using index paths, reusable cells, and multiple tables; format item descriptions and due dates and wire checkboxes.

Format dates in table views by creating a format day function using a date formatter, then apply it across to-do items, manage checkbox state, and update core data.

Troubleshoot an iOS to-do app crash by tracing the wrong array in the main table view, using breakpoints and conditional checks, and applying core data for data integrity.
