Bauly

Bauly is a neat little library used to display compact message banners in your app. The design is inspired by stock banners visible in iOS 13 and newer.

• Written in Swift 5
• iOS 10+ support
• Rotation, Dynamic Type, and Dark Mode support
• Haptic feedback
• Available via Swift Package Manager

Installation

Bauly can be installed via Swift Package Manager. To use it in your project, open Xcode, go to menu File -> Swift Packages -> Add Package Dependency, and paste this repo's URL:

https://github.com/wiencheck/Bauly.git

Usage

Bauly is managed via a shared singleton instance. It internally manages a queue of pending banners. Only one banner can be displayed at a time. Remember to call these methods only from the main thread.

Displaying banner

To display a banner, simply use the present method and provide title and other information for the banner:

public func present(title: String, 
                subtitle: String?, 
                icon: UIImage?, 
                duration: TimeInterval, 
                dismissAfter delay: TimeInterval, 
                in window: UIWindow?, 
                feedbackStyle: UIImpactFeedbackGenerator.FeedbackStyle?, pressHandler: (() -> Void)?, 
                completionHandler: (() -> Void)?)

Customizing banner

In addition to the method described above, banners can be presented using a present(configurationHandler:...) method which provides the ability for directly customization of the banner:

func present(configurationHandler: ((BaulyView) -> Void)?, 
            duration: TimeInterval, 
            dismissAfter delay: TimeInterval, 
            in window: UIWindow?, 
            feedbackStyle: UIImpactFeedbackGenerator.FeedbackStyle?, 
            pressHandler: (() -> Void)?, 
            completionHandler: (() -> Void)?)

By calling this method, you can customize the appearance of the banner and its other properties directly, for example:

Bauly.shared.present(configurationHandler: { bauly in
    // Tint is applied to the icon and title of the banner
    bauly.tintColor = .systemPurple
    bauly.visualEffect = .extraLight
    bauly.title = "This is Bauly!"
    bauly.subtitle = """
    Press me to have a little fun with colors.
    Btw, I support mutli-lined text and emojis easily
    😏
    """
    }...)

Displaying banner immediately

Both methods used for presenting a banner have a sibling method which forces the banner to be displayed immediately. It takes the same arguments as normal methods.

func forcePresent(...)

Dismissing banner

To manually dismiss the banner, use the dismiss method

func dismiss(completionHandler: (() -> Void)?)

Note If you want to use the completionHandler of this method, you should always check if any banner is currently visible before calling this method, by reading the currentBanner property, for example:

...
if Bauly.shared.currentBanner == nil {
    return
}
Bauly.shared.dismiss {
    print("Old banner dismissed!")
}
...

It's important as the completionHandler of this method doesn't get called if no banner has actually been dismissed.
