[jira] [Comment Edited] (CB-13281) Cordova crashes with
UIPopoverPresentationController exception in web forms
[ https://issues.apache.org/jira/browse/CB-13281?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16191431#comment-16191431 ]

Repro steps:
1. Open this project in iOS 10+
2. Select the top "input" (I recommend using an ios emulator, but a real device with a keyboard will do)
3. Start tabbing quickly. You may need to go back to the top one and do it several times. (It doesn't cycle back to the top).
4. Eventually the app will crash. (It took me about 3 go rounds.) If you've got xcode open, this will look like an uncaught exception breakpoint and the app freezing.

> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
> The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

> Probably at least one of the constraints in the following list is one you don't want.
> Try this:
> (1) look at each constraint and try to figure out which you don't expect;
> (2) find the code that added the unwanted constraint or constraints and fix it.
