    <p>I have an app that runs a synchronization algorithm.</p> <p>When I build and run it in debug mode (onto my iPhone 5) it all works fine.</p> <p>However, when I archive it and upload it to TestFlight and then download and install to the same iPhone 5 then part of the sync doesn't work.</p> <p>It doesn't crash or anything, it just doesn't run that part of the sync.</p> <p>The stupid thing is that it is a line of code inside a single function that isn't running. Everything else in that function does run.</p> <p>I have no idea where to start looking for this.</p> <p><strong>EDIT</strong></p> <p>With help from Mindaugas I've found exactly why and which bit of code is not being run.</p> <p>The function is...</p> <pre><code>- (void)uploadData { NSLog(@"pushing photos"); for (StoredImage *storedImage in self.recordArray) { NSURL *url = [self urlForImageUpload:storedImage]; if (url == nil) { continue; } ImageUploadOperation *uploader = [[OJFImageUploadOperation alloc] init]; uploader.image = storedImage.image; uploader.url = url; [self.recordQueue addOperation:uploader]; } } </code></pre> <p>When I set the optimisation level to "Fastest, Smallest" it seems to mess the order of this function up.</p> <p>When it enters I can see that there is a single object in the array and it enters into the loop. But then it completely skips past the first line <code>NSURL *url = [self urlForImageUpload:storedImage];</code> and goes to the end. So the upload never actually starts and it moves onto the next item.</p>

    1. COMy only thought is if the call is inside of an NSAssert method then it will turn into a no-op.

    3. COI'm not using NSAssert at this point. I'm just adding in some TestFlight checkpoints to find out exactly which bit isn't being run.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
