I am using the Salesforce iOS SDK for Customer Support (https://github.com/forcedotcom/ServiceSDK-iOS). With the update to iOS 13 the view disappears right after showing. I cannot edit the code so I have to ask if someone has the same problem and worked out some workaround.
Yes, I'm in the same boat.
Here's an official statement from Salesforce saying that a new SDK should be available starting October 7.
There was a discussion about this on GitHub also, but they've removed issues from their repo recently.
I guess we'll just have to wait until next week.
