SwiftUI First Responder is a Swift package that provides easy control over the first responder in iOS prior to 15.0 and macOS prior to 12.0, using SwiftUI style APIs for TextField, SecureField, and TextEditor.
- SwiftUI style APIs for TextField, SecureField, and TextEditor.
- Tap outside to resign the first responder.
- Designed for iOS and macOS apps.
TextField("Name", text: $name)
.firstResponder(id: FirstResponders.name, firstResponder: $firstResponder, resignableUserOperations: .all)
TextEditor(text: $notes)
.firstResponder(id: FirstResponders.notes, firstResponder: $firstResponder, resignableUserOperations: .all)Before iOS 15.0 and macOS 12.0, SwiftUI did not offer official support for controlling the first responder of text inputs. When we began enhancing our QuickPlan app's user interfaces using SwiftUI, we realized that the first responder control had a significant impact on the user experience.
Our aim was to create a solution with the following principles:
- Continue to use SwiftUI views.
- Use SwiftUI style API calls to control the first responder.
- Add additional controls for events like tapping outside or pressing the escape key.
- This package provides a temporary solution for controlling the first responder for iOS prior to 15.0 and macOS prior to 12.0.
- This solution depends on the run-time (UIKit and AppKit) view structure - the code analyzes the run-time views and adds additional controls to the UIKit and AppKit views.
- It may NOT work in the future. The method used for this solution may not be possible as the SwiftUI implementation may change.
