After successfully signing in, you need to set up some information that will allow Apple to identify your App. You will need to assign aBundle ID, which is a unique identifier for your App. You can assign the Bundle ID directly from Xcode. Click the outermost file in your Project navigator, the blue-icon “Project” file. In this new screen, make sure you’ve selected your App in the “Targets” section.

In the “General” tab, the “Identity” section lists the Bundle ID. You can edit it directly in that section. The typical Bundle ID is named for your App and your organization with theReverse Domain Name format:com.{your-org-identifier}.{your-app-identifier}. For example, the Pink Rocket app from Star Rockers Industries might have the Bundle IDcom.starrockers.pinkrocket.

Generating a Development Certificate

Once your Bundle ID has been added, Xcode will be able to generate aDevelopment Certificatefor you. With your App still selected in the “Targets” section, select the “Signing & Capabilities” tab.

Tap the “Team” selector and select your Apple ID from the list. Make sure that the “Automatically manage signing” option is checked, and that your name appears in the “Team” section. Once these options are entered correctly, you should see some loading indicators; Xcode is reaching out to the Developer Portal to create a certificate for you. If you don’t see error text after the loading indicators disappear, that means the certificate exists. Xcode handles this process automatically!

Creating a Provisioning Profile

In order to run your App onto a personal device and build it for the App Store, you will also need aProvisioning Profile. At this point in the walk-through, the profile can be created automatically from Xcode as well.

Apple needs to add one device to your account in order to create a profile. This can be done via plugging an iOS device into your computer, then picking it in the devices selector. This process will resolve any potential errors you may have encountered in the previous step.

Wrap up

With no errors on the “Signing and Capabilities” page, you now have your development certificate and provisioning profile. Congratulations! In the next article, we will show you how to turn your code into a file that can be downloaded as your App!
