Question 1

How to handle multiple gestures with RxGesture?

Accepted Answer

Use the .anyGesture() method to combine gestures like tap and swipe, then subscribe to the observable. For example, view.rx.anyGesture(.tap(), .swipe([.up, .down])) allows unified handling, as shown in the README demo.

Question 2

RxGesture vs UIKit gesture recognizers – which is better?

Accepted Answer

RxGesture is better for RxSwift-based apps needing reactive, composable gesture handling, while UIKit recognizers are simpler for imperative code or projects without RxSwift. RxGesture adds overhead but enables seamless integration with other Rx streams.

Question 3

Can I use RxGesture with SwiftUI?

Accepted Answer

No, RxGesture is designed for UIKit and AppKit, not SwiftUI. SwiftUI has built-in gesture modifiers that are reactive with Combine, so RxGesture isn't compatible and would require bridging layers.

Question 4

How to filter gesture states in RxGesture?

Accepted Answer

Use the .when() operator after a gesture call, e.g., view.rx.tapGesture().when(.recognized) to only emit events when the gesture is recognized. The README provides state tables for preferred filtering per gesture type.

Question 5

Does RxGesture support custom gesture recognizers?

Accepted Answer

No, RxGesture only wraps native UIKit/AppKit gesture recognizers listed in the README. For custom gestures, you'd need to implement your own RxSwift wrappers or use alternative approaches.

Question 6

What's the performance impact of using RxGesture?

Accepted Answer

There's a slight overhead due to RxSwift's observable streams compared to direct delegate calls, but for most apps, it's negligible. Performance concerns mainly arise in high-frequency gesture scenarios or on older devices.
