Hi, I have send a feedback and upload a sample project, please help to analyze: FB15953241 (Fatal Exception: NSInternalInconsistencyException Attempting to select a view controller that isn't a child! (null)) Thank you very much.

Hi, my next post include the sample code, please look at that code and see if you can find any problems, thank you~

Hi, before you call setViewControllers, should check if ViewController's view has loaded: guard isViewLoaded else { return }

Not yet. May I ask if you have found a solution
