9 SwiftUI Alerts, Sheets and Modals

Описание: SwiftUI Tutorial #9 — Alerts, Sheets & Modals (Presenting Messages & Additional Screens)

In this lesson, we dive into how SwiftUI presents UI elements that overlay or expand the interface, such as alerts, sheets, and full-screen covers. These tools help you guide users, request decisions, show options, and open secondary views smoothly.

We'll not only implement each one — we’ll understand their purpose, behavior, and correct usage in real app scenarios.

What We Cover in This Video

1. Alerts (Pop-up messages with buttons)

Showing important messages or confirmations
Multiple button alerts (Yes / No / Cancel actions)
Triggering alerts using .alert(isPresented:)

2. Sheets (Half-screen modal presentations)

When to use sheets vs pushing views
Presenting and dismissing sheets
Passing data into a sheet

3. Full-Screen Covers

When the sheet isn't enough
Ideal for onboarding, login, or immersive screens
Using .fullScreenCover() cleanly

4. Action Sheets / Confirmation Dialog

Displaying lists of actions
Context menus vs action sheets
iOS modern .confirmationDialog usage

5. Handling Multiple Sheets

Presenting different screens based on selection
Bool vs enum based presentation logic
Writing maintainable presentation code for real apps



Outcome

After this video, you’ll be able to confidently present:
Alerts with multiple actions
Sheets and full-screen modals
Contextual action sheets
Multiple different sheets based on user selection

All while keeping your state clean, predictable, and easy to maintain.
