You must create a unique Bundle ID of your own. You have to choose this Bundle ID while creating new App in iTunes Connect.
​
Note:
Make sure that In-App Purchase and GameKit are enabled by default.

Create In-App Purchases Product IDs

• Now,you have to set up some required In-App Products  in iTunes Connect.
• You can see  a button in iTunes Connect (+) , just click to add  your own In-App items.

​

You will get to a screen that lets you select the type of In-App Purchase you want to add. Note that there are are two types of frequently-used In-App Purchases:

1)Consumable:
​
This kind of product can be purchased multiple times, and not just once.

Example:
In a game a consumable product can be a number of extra lives for the main hero.
Consumable products unlock app features just for a small period of time, and they don’t have permanent effect.


2)Non-Consumable:

This category is the exact opposite to the previous one, and as you understand the purchase of a non-consumable product is made just once.

Example:
Buying extra fonts for a text-editing app must be done just one time, and the extra fonts must be available from there on and forever.

To enable In-APP Purchase in our project.
​
STEP 1:

Starting from the second objective, open the starter project in Xcode, and once it gets launched click to the project target in the Project Navigator.

Then, in the General tab and inside the Identity section, click to the Team dropdown control and select your developer account, just as shown below.

​

1. Open the Xcode > Preferences
2. Click to the Accounts tab.
3. Click to the small plus button to the bottom-left side and select the Add Apple ID.
4. To the modal window that appears enter your Apple ID and password, and then click Add.
