Hello,
I found the solution to my problem.
Below I have included my code. I hope this helps anyone who has struggled with getting this working as I have.
EditorToolViewController.h:
#import <UIKit/UIKit.h>
@import WebKit;
@interface EditorToolViewController : UIViewController <WKNavigationDelegate>
// Header
@property (weak, nonatomic) IBOutlet UIImageView *imageView;
@property (weak, nonatomic) IBOutlet UILabel *titleLabel;
@property (weak, nonatomic) IBOutlet UIButton *summaryButton;
// Body
@property (weak, nonatomic) IBOutlet UIView *container;
@property (strong, nonatomic) NSString *editorContentHTML;
// - Summary
@property (strong, nonatomic) NSString *summaryContentHTML;
@property (strong, nonatomic) NSString *packStringSummaryValue;
@property (strong, nonatomic) NSString *userStringSummaryValue;
@property (strong, nonatomic) NSString *nameStringSummaryValue;
// Footer
@property (weak, nonatomic) IBOutlet UIToolbar *toolbar;
@property (weak, nonatomic) IBOutlet UIBarButtonItem *revertButtonItem;
@property (weak, nonatomic) IBOutlet UIBarButtonItem *saveButtonItem;
@end
