Enter my mobile phone number on the web page and run the Send event.

Then, "From Messages" appears on the keyboard.

If press this and modify the text, App Crash will occur.

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.

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.

The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

The beginning is:

- a begnin keyboard alert

- some issue with the constraints you have defined.

The crash is

2019-11-27 10:53:52.351472+0900 cm-ios[8668:2911641] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSCFString stringByReplacingCharactersInRange:withString:]: nil argument'

But you should give more context and precise information:

Enter my mobile phone number on the web page and run the Send event

How is this web page created ?

How do you set the content (loadRequest ?)

run the send event :

what do you mean ?

Is it the MailComposer page ?

What is the crash log (not only the message on console) ?

Could you also show the code and show exactly where it crashes.

Focusing on the crash ignores the layout constraint issue, with constraints being generated by IOS. The constraint resolution system is forced to break a constraint when this should not be happening.

I'm experiencing what I think is the same root issue when working with a UITextView inside a UIStackView inside a UIScroll view, where the error messages involves ONLY constraints added by iOS:

2019-12-22 09:17:24.662016-0700 IgCares[43151:3421009] [LayoutConstraints] Unable to simultaneously satisfy constraints.

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.

(

"<NSLayoutConstraint:0x600000b35720 'assistantHeight' TUISystemInputAssistantView:0x7fa28c5222f0.height == 44 (active)>",

)

Will attempt to recover by breaking constraint

Turning off correction for the field in question should resolve the error.
