Features

• Add a variation on the .swiftMessage() modifier that takes a view builder instead of requiring that the bound value conform to MessageViewConvertible. This syntax is more similar to the familiar sheet() modifier syntax and provides more flexibility for constructing message views.
• #207 Add optional haptic feedback

Changes

• Use @MainActor to ensure that SwiftMessages is not called from a background queue.
• Bump minimum deployment target to iOS 13.

Fixes

• #535 window being accessed from background thread when dequeueNext is called
• #534 Xcode warnings in two swift files
• #533 How do I show a message that appears above the keyboard, when the keyboard is already visible?
