ViewController.h
@interface ViewController : UIViewController{
IBOutlet UITextField *Signup;
IBOutlet UITextField *Login;
}
@property(nonatomic, retain)IBOutlet UITextField *Signup;
@property(nonatomic, retain)IBOutlet UITextField *Login;
-(IBAction)TYPE:(id)sender;
ViewController.m
@synthesize Signup;
@synthesize Login;
-(IBAction)TYPE:(id)sender{
[Signup resignFirstResponder];
[Login resignFirstResponder];
}
In Simulator when I click on the textfield I get the following error message:

I haven't used Xcode in 2 years, but this same code worked fine then, why doesn't it work for Xcode 8, iOS 10?
The simulator for Xcode 8 is quite verbose. Those messages don't mean anything special.
-- BTW --
Your code is written in a very old style that isn't best practice anymore. Better is:
@interface ViewController : UIViewController
// It's no longer necessary to have your properties between { and }
@property (nonatomic, weak) IBOutlet UITextField *signup;
@property (nonatomic, weak) IBOutlet UITextField *login;
// IBOutlets should be weak, other properties should be weak or strong for objects, or assign for structs and values.
@end
@implementation ViewController
// You don't have to synthesize your properties anymore.
- (IBAction)type:(id)sender {
[self.signup resignFirstResponder];
[_login resignFirstResponder];
// but you do have to either use self. or underscore to refer to them.
}
@end
