Thank you for using Syncfusion Products.
We have checked the reported issue “SfListView binding is not working when AllowSwiping is set to true” at our end by defining the AllowSwiping as “True” and bind a underlying collection to the ItemsSource property but we didn’t face any issue as reported. From the given information, we suspect that the exception “System.InvalidOperationException: The BindableProperty "Width" is readonly” throws due to assigning the value to the Width property in the application which is readonly type. And also we would like to let you know that AllowSwiping property enables the swiping option only in SfListView. So, we highly recommend you to ensure that whether you have assigned any value to the Width bindable property in your application.
For your reference, we have attached the working sample which enables the swiping option and bind a underlying collection to the ItemsSource property and you can download it from the below location.
Please let us know if you require further assistance.
