PopupDialog
A customizable popup dialog for iOS written in Swift, designed to replace UIAlertController's alert style.
What is PopupDialog?
PopupDialog is a Swift library for creating customizable popup dialogs in iOS apps. It provides a modern alternative to UIAlertController, allowing developers to design alerts with images, custom layouts, and advanced styling options. It solves the problem of limited customization in native iOS alert controllers.
iOS developers building apps that require branded, highly customizable alert dialogs beyond the standard UIAlertController capabilities.
Developers choose PopupDialog for its extensive theming system, smooth animations, and easy API that reduces boilerplate code while offering full control over dialog appearance and behavior.
Overview
A simple, customizable popup dialog for iOS written in Swift. Replaces UIAlertController alert style.
Use Cases
Best For
- Replacing UIAlertController with a more customizable alternative
- Creating branded alert dialogs with custom images and layouts
- Implementing popups with gesture-based dismissal (swipe/tap)
- Building iOS apps that require consistent, themeable alert designs
- Adding animated transitions (bounce, zoom, fade) to dialogs
- Supporting both Swift and Objective-C in the same project
Not Ideal For
- Projects targeting iOS versions below 10.0, as the library requires a minimum of iOS 10.0
- Teams building exclusively with SwiftUI who prefer native declarative UI components over UIKit
- Apps requiring ultra-lightweight dependencies without manual library additions, since manual installation needs DynamicBlurView
- Developers needing cross-platform or server-side solutions, as PopupDialog is iOS-only
Pros & Cons
Pros
The API is straightforward with minimal boilerplate, as shown in the example code for creating dialogs with just a few lines.
Fully themeable via UIAppearance for fonts, colors, shadows, and more, allowing consistent styling across an app without repetitive code.
Offers multiple transition styles like bounce, zoom, and fade, providing polished presentations that enhance user experience.
Supports dismissal via swipe or background tap, adding intuitive interaction options beyond standard button taps.
Works seamlessly in both Swift and Objective-C projects, as demonstrated in the README with example code for both languages.
Cons
If not using CocoaPods or Carthage, manual installation requires adding DynamicBlurView files separately, increasing setup complexity.
Enabling live blur for real-time background updates significantly increases CPU usage, as noted in the README, which can impact battery life.
Tied to UIKit and not compatible with SwiftUI, making it less ideal for modern iOS projects adopting declarative UI frameworks.
Changelog shows updates tied to Swift version jumps (e.g., Swift 5 support), which may require code adjustments and cause migration headaches.
