At 7:17 you set the completion handler to none and in previous line you assigned it (true, response.products). Why did you do that.

What I did was first call the completion handler, and then I set the completion handler to none. That clears out the closure. Otherwise, we would hold on it until another request. By setting it to none, we are reclaiming that unused memory. I hope that makes sense.

In iOS14 and Xcode 12 I am getting an error that self?.tableView.reloadData() in requestAllProducts() needs to happen on the main thread.

Me too. I’m having errors as well and the products aren’t showing up.  
Just spent 50$ and a day on this tutorial and it doesn’t even work. Very frustrating.

The good news is that we are currently editing the updated version of this course and should be released soon.

Regarding the thread error, the call should be in a DispatchQueue as follows:

```
DispatchQueue.main.async { [weak self] in
    self?.tableView.reloadData()
}

```

Note there could be lots of reasons why the products may not be showing up. If you have a specific error, feel free to post here or let me know what you’ve been encountering.

Thanks!

Hi, thanks for the quick response! Really appreciate it!

Do you mean like this:

Regarding the errors, this is my log:

Glad to help!

Some background as to what is happening based on the log you posted. The code was trying to update the user interface from a background thread. This will break the UI so anytime you need to update the user interface from the background or get that kind of error message, you need to call it on the main thread which is what that DispatchQueue code does.

So with that in mind, I’d update it to the following:

```auto
 @objc func requestAllProducts() {
     OwlProducts.store.requestProducts {
       [weak self] success, products in
       if success, let products = products {
         self?.products = products
         DispatchQueue.main.async { 
             self?.tableView.reloadData()
         }
       }
       DispatchQueue.main.async {
           self?.refreshControl.endRefreshing()
       }
     }
   }

```

I removed the [weak self] from the DispatchQueue code because you are already capturing self as weak in requestProducts.

Also note that I put the DispatchQueue code around the refresh control since that’s a UI element that also needs to be updated on the main thread. That should resolve that background error. Hopefully with that fix, fingers crossed, you should get products back. Let me know if you run into any other issues.

Cheers!

Hi!  
Again, thanks for the quick reply!

Indeed now there are no errors or crashes, but the products still don’t appear.  
I’ve gone over the troubleshooting video but it seems like everything is in place.

I’ve also added print commands so I know that “requestProducts” method in IAPHelper is being called and the response is received successfuly. 🤔🤔

EDIT: So far I’ve managed to narrow it down a bit. It appears the response is received but “response.products” is an empty array.

Interestingly I still get this error _after_ I terminate the app run:

The hard part in all of this is determining why products aren’t returning. The most obvious is the product names in your app must exactly match the products you put in App Store Connect.

com.razeware.iap.HappyOwl ← app store connect  
com.razeware.iap.HappyOwl ← your app

Casing matters. Each identifier must be exactly as you have it in App Store Connect. These two are different:

com.razeware.iap.HappyOwl  
com.razeware.iap.happyowl

Next, your bundle identifier of your project must match the profiles in the developer center. Make sure you have your project using the correct signing. Also Remember, you must be using a paid apple developer account. This won’t work for a free account.

Make sure your in app purchases are ready for review in app store connect (you can get away with missing metadata)

All your agreements must be signed. Make sure to go to the agreements section and check every category.

Basically, you need to go over everything with a fine tooth comb. If just one thing is amiss, Apple won’t send you back the products. It’s frustrating - I was just there. If you continue to run into walls, the next best solution is to jump on RW Chat - the discord app. There are lots of iOS developers on there who may provide some additional guidance.

It looks like there was some kind of error on the AppStoreConnect’s side.  
After refreshing the site, now it’s working!

I thought it might be a problem with localization since I’m not in the US, so I went to one of the non-consumables and add my localization. Thing is that after I did that _all_ of the IAP appeared at once. And so I went back and removed my localization, and it’s still working perfectly fine!

Dmannit… go figure…

Sorry for wasting your time, and thanks again for the support! Very much appreciated!

No worries at all! Getting them to show up can be tricky. It’s probably the most frustrating part of the process since Apple gives zero feedback about why it failed. It’s all detective work. Thankfully, in Xcode 12 we can actually build them in the editor which is covered in the updated course which makes them easier to use.

In any case, congrats on working through it. Feel free to reach out to me if you get stuck again.

Cheers!
