UIPasteboard Attributed Text Crash

pasteboard.m

- (void)copy:(id)sender {
    
    // calling the following crashes the app instantly
    // due to a possible bug in iOS 12.1.4.
//    [super copy:sender];
    
    NSRange range = self.selectedRange;
    
    if (range.location != NSNotFound && range.length > 0) {
        
        UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
        
        if (self.attributedText.length >= (range.length - range.location)) {
            
            NSError *error = nil;
            
            NSData *rtf = [self.attributedText dataFromRange:range
                                          documentAttributes:@{NSDocumentTypeDocumentAttribute: NSRTFTextDocumentType}
                                                       error:&error];
            
            if (error != nil) {
                DDLogError(@"Error creating NSData from attributed text for copying to pasteboard: %@", error);
                
                return;
            }
            
            pasteboard.items = @[@{(id)kUTTypeRTF: [[NSString alloc] initWithData:rtf encoding:NSUTF8StringEncoding],
                                   (id)kUTTypeUTF8PlainText: self.attributedText.string}];
            
        }
        
    }
    
}

temporary work-around:

@try {
    // ....
}

@catch (NSException *exc) {
    NSLog(@"Exception when copying attributed text: %@", exc);
    
    pasteboard.string = [[self text] substringWithRange:range];
}
