Hi,
If you want to select image from device in Xcode, you can use the below code for this.

#import <uikit.h>
@interface ViewController : UIViewController&lt;UIImagePickerControllerDelegate,UINavigationControllerDelegate&gt;
{

_weak IBOutlet UIButton *ImageButton;
  _weak IBOutlet UIImage *image;
}

@property (strong,nonatomic) IBOutlet UIImageView *imageView;


-(IBAction)selectPhoto:(UIButton *)sender;
-(IBAction)takePhota:(UIButton *)sender;



@end

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

}

- (IBAction)selectPhoto:(UIButton *)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentViewController:picker animated:YES completion:NULL];


}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *chosenImage = info[UIImagePickerControllerEditedImage];
    self.imageView.image = chosenImage;

    [picker dismissViewControllerAnimated:YES completion:NULL];

    }
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{


    [picker dismissViewControllerAnimated:YES completion:NULL];
}



@end
