Hello, I am using Xcode 15.3 and doesn't add any support for Apple Intelligence yet as it requires Xcode 16+. But I see many crashlogs related to Apple Intelligence, I assume crash is related to UITextView element of UIKit.

Can you please help me to resolve this issue, how can I fix it?

There are few lines of the crashlog, they are all similar.

Thank you for providing the complete crash report. We have identified the issue, it is a compatibility problem with the JSQMessagesCellTextView component of the third-party JSQMessagesViewController library. Specifically, that subclass of UITextView returns an invalid NSRange from its selectedRange property.

As an immediate workaround, if you are integrating that library using its source code into your project, change the implementation from this:

- (NSRange)selectedRange
{
    //  attempt to prevent selecting text
    return NSMakeRange(NSNotFound, NSNotFound);
}

to this instead:

- (NSRange)selectedRange
{
    //  attempt to prevent selecting text
    return NSMakeRange(0, 0);
}

Please submit a bug report using Feedback Assistant and attach the complete crash report file so we can investigate further.

Share the FB# here once you have submitted it. We will need the complete crash log to investigate this.
