Publish an iOS application in the AppStore

iOS App publishing Tools

The next step after creating your application, is to publish an iOS application in the AppStore. This is a “quick” guide to publish iOS applications, if we want to make them public to the world. The process could be long for the first time.

The main steps involved in this process are:

  1. Create an Apple ID
  2. Join the Apple’s Developer program
  3. Create and build your application in Xcode
  4. Create an archive of your signed application
  5. Register your application in App Store Connect
  6. Upload or export your application
  7. Submit your application for Review
  8. Your application will be verified and published in the App Store.

Create an Apple ID

The rest of the process requires an Apple ID. To create an Apple ID you need a valid email address, and you can do it by different ways:

Apple ID creation

You need to enter identification information and some personal data. After validating your email with a security code, you account will be active.

Register as a Developer

The next  step is to register in the site as a Developer, to start publishing applications in the AppStore.

  1. Enter in the Apple developer’s site 
  2. Accept the Apple Developer Agreement
  3. You will enter in the Developer’s portal

Apple developer portal

With this account you have limited access to general resources for developers (SDKs, downloads, development tools). After that, you need to join the Apple’s Developer Program to access all the features, including publishing apps to the AppStore.

Join the Apple Developer Program

You need to Join the Apple Developer Program to start publishing apps.

  1. In the main page, you can click on  the “Join the Apple Developer Program
  2. Click on the button link “Enroll
  3. Start your enrolment as an Individual or as an Organization.
  4. You need to enable Two factor authentication for your apple account, in your iPhone or MacBook.
  5. After entering the information needed to enroll, you will be prompted to pay $99 for a one-year subscription membership.

This last step allows you to publish an iOS application in the AppStore, as well as for MacOS applications.

Note: After submitting and paying for your iOS Developer registration, you’ll need to wait for Apple to process your order. 

Generate App Certificates

After validating your new developer account. You will be able to work with the publishing tools in the Apple developer site. The first step to publish is to generate application certificates:

Create a CSR file

Keychain access - create certificate

  1. In the Applications folder on your Mac, open the Utilities folder (Other folder) and launch Keychain Access.
  2. Select Keychain Access > Certificate Assistant > Request a Certificate from a Certificate Authority.
  3. In the Certificate Information window, enter the following information:
    1. User Email Address
    2. Create a name for your private key (e.g., MyDevKey).
    3. The CA Email Address field should be left empty.
    4. In the “Request is” group, select the “Saved to disk” option.
    5. Click Continue within Keychain Access to complete the CSR generating process.
  4. Save the certificate to disk and keep it accesible for the next steps.
Upload your certificate to your developer account
  1. Go to the “Certificates, Identifiers and Profiles” link (
  2. You will see all your certificates created. It will be empty for the first-time.
  3. Upload this certificate file in the Apple Developer site
  4. After upload, it will generate an ios_distribution.cer certificate. Download it to your computer.
  5. Open theios_distribution.cer file, and when prompted, add it to your local Keychain Access.

Register Devices

You don’t need a real iOS device to publish your application, but if you are planning to test or deploy your application to some testing devices, you need to register them in Apple Developer portal:

  1. Connect your phone to a MacBook and open the iTunes app
  2. Select the current iOS device from the sidebar and you will see some info about your phone. Copy the UDID code.
    submit an app
  3. Open the Apple Developer portal and select from the sidebar  “Devices” -> “All” 
  4. Click on the “Add” button (plus sign) and register the name of your device, and paste the UDID from the iTunes application.
  5. Now you can install and test applications created by you directly in your phone.

Create an Application ID

Each application needs an Unique ID to be registered in the App Store.

  1. Open the Apple Developer portal and select from the sidebar  “Identifiers” -> “App IDs” 
  2. Click on the “Add” button (plus sign) and register the name and id of your application.
    1. The App Name is a global identifier for your application in the App Store.
    2. The App ID suffix is like a reverse DNS address for your application (example: com.mycompany.apps.demo)
  3.  Activate the services used by your application. Generally, if you are using only standard components, you can leave this section as is.
  4. Use the App bundle identifier as the in your Xcode project.

Create Provisioning Profiles

You will use Development provisioning profiles to build and install versions of your app during your development process. You use Distribution provisioning profiles when you submit your apps to the App Store.

  1. Open the Apple Developer portal and select from the sidebar  “Provisioning Profiles” -> “All” 
  2. Click on the “Add” button (plus sign) and register a new provisioning profile
    1. First of all, select iOS App Development to create a development provisioning file:
      1. You need to specify an App ID (the last Bundle ID created in the previous step)
      2. Select the computers where you plan to develop and test your application.
      3. Select the iOS devices to use for testing
      4. Create a profile name (example: Myapp.development)
      5. Download the generated provisioning file.
    2. Second, Add another profile for App Store distribution provisioning
      1. Select the App bundle ID, computers for development and iOS devices for testing, like in the previous step.
      2. Download the provisioning file
      3. You can specify the provision file in your Xcode project configuration. Also, if you have registered your Apple Id in Xcode, the application manages automatically the certificates and provisioning, providing only the App Store account as a team.
  3. Now you can test and prepare applications for publishing.
