“No type or protocol named …” after adding bridging header XCode 12.1

This project target breaks when an umbrella header is added.

Now there is an error of "No type or protocol named 'ComposeDelegate'" on of the target's existing <ComposeDelegate> protocols. This code had no errors before an umbrella header etc.
Any suggestions?
Code Block
ComposeViewController.h
Code Block
@class ComposeViewController;
@class DataModel;
@class Message;

Code Block
// The delegate protocol for the Compose screen
@protocol ComposeDelegate <NSObject>
- (void)didSaveMessage:(Message*)message atIndex:(int)index;
@end

Code Block
@interface ComposeViewController : UIViewController /*<UITextViewDelegate>*/
Code Block
@property (nonatomic, assign) id<ComposeDelegate> delegate;
@property (nonatomic, strong) DataModel* dataModel;
@property (nonatomic, strong) AFHTTPClient *client;
@end


Still the same error
