The sequence to make the connection is important.

self.photoOutput = [[AVCapturePhotoOutput alloc] init];
AVCapturePhotoSettings *photoSettings = [AVCapturePhotoSettings photoSettingsWithFormat:@{AVVideoCodecKey : AVVideoCodecJPEG}];
if ([self.session canAddOutput: self.photoOutput ]){
     [self.session addOutput: self.photoOutput]
}
[self.photoOutput capturePhotoWithSettings:photoSettings delegate:self];

You need to call [self.session addOutput:]; before [self.photoOutput capturePhotoWithSettings:delegate:];

Try:

self.photoOutput = [[AVCapturePhotoOutput alloc] init];
        AVCapturePhotoSettings *photoSettings =
            [AVCapturePhotoSettings photoSettingsWithFormat:@{AVVideoCodecKey : AVVideoCodecJPEG}];
[self.photoOutput capturePhotoWithSettings:photoSettings delegate:self];
[self.session addOutput:self.photoOutput];
