A segue can be performed even when an alert is showing. This is not good behavior and can lead to unexpected UI states.

Steps to Reproduce:
I have the following UI elements:

* A table view cell with an associated segue
* A save button that shows an alert if data is missing

Do the following:

* Tap and hold the cell
* While holding cell, tap the save button
* Let go of cell

Expected Results:
Alert is presented and segue is not performed

Actual Results:
Alert is presented and the segue shows behind it.
