Description

Homes.com is encountering the below error when toggling between annotations on a map when using the map camera. See their message here: "The issue pertains to centering the map on top of an annotation after it is clicked. The idea is that when a user clicks on a map annotation, the map will move over the annotation and then a custom popup will load over the annotation. We were able to make the map pan over an annotation by updating the map region. However, because specifications provided required that the map be zoomed in a lot closer to the pins, it meant that we had to use the map camera on iOS. Doing this lead to the issue we are now experiencing. Please find attached a copy of a simple project that shows this issue and a copy of the error log we get. Also, the error that we get has only happened on the device and not in the simulator." Below is the crash as I encounter it. Attached is the sample project and the customer's log.

I no longer witness the issue with the updated module. It has been passed on to the customer.
