iOS Q & A


What are provisioning profiles and certificates?

Provisioning profiles and certificates are essential components of iOS app development and distribution, enabling developers to deploy their apps on real devices and distribute them through the App Store. Here’s an overview of provisioning profiles and certificates and their roles in iOS development:

Certificates: Certificates are cryptographic keys issued by Apple to verify the identity of developers and their apps. There are two main types of certificates used in iOS development:

  • Developer Certificate: A developer certificate identifies an individual developer or a team of developers associated with an Apple Developer account. Developer certificates are used to sign apps during development and testing.
  • Distribution Certificate: A distribution certificate is used to sign apps for distribution on the App Store or through other distribution channels. Distribution certificates are required to submit apps to the App Store and ensure that they come from a trusted source.

Provisioning Profiles: Provisioning profiles are configuration files that include information about an app’s bundle ID, entitlements, devices, and certificates. Provisioning profiles specify which devices can run a particular app and whether the app is intended for development, ad-hoc distribution, or app store distribution. There are several types of provisioning profiles:

  • Development Profile: Development profiles are used during the development and testing phase of an app. They allow developers to install and test their apps on registered devices directly from Xcode.
  • Ad-Hoc Profile: Ad-Hoc profiles are used for distributing apps to a limited number of registered devices outside of the App Store. Ad-Hoc distribution is commonly used for beta testing or internal testing within an organization.
  • App Store Profile: App Store profiles are used for submitting apps to the App Store for distribution to the general public. They ensure that apps are signed with a valid distribution certificate and comply with App Store guidelines.


Provisioning profiles are generated and managed in the Apple Developer portal and must be associated with the appropriate certificates. Developers can create, download, and install provisioning profiles for their apps using Xcode or manually through the Apple Developer portal.


Provisioning profiles and certificates play a crucial role in ensuring the security, integrity, and trustworthiness of iOS apps. By properly configuring provisioning profiles and certificates, developers can deploy their apps on real devices for testing and distribute them to users through the App Store with confidence.
