iOS Application Signing Everything You Need to Know
iOS application signing is a crucial process in the app development world. It is the process of digitally signing an iOS application with a cryptographic key. It ensures that the app comes from a verified source and has not been tampered with since its creation.
What is Apple Signatures?
Apple provides developers with digital signatures, called Apple Signatures, to ensure the authenticity and integrity of their applications. The Apple Signature is a hash value of the app’s executable file and is computed using the developer’s digital certificate and private key.
Types of iOS Signing:
There are three types of iOS signing:
Development Signing
Distribution Signing
Enterprise Signing

Development Signing
Development signing is used when an iOS app is in the development phase. It is done to test the app’s functionality before distributing it to users. The signing certificate used in this phase is a development certificate, which is provided by Apple to registered developers.
Distribution Signing
Distribution signing is used when an app is ready to be released to the public. The signing certificate used in this phase is a distribution certificate, which can be obtained from the Apple Developer portal.
Enterprise Signing
Enterprise signing is used by companies that want to distribute their apps to their employees without going through the App Store. The signing certificate used in this phase is an enterprise certificate, which can also be obtained from the Apple Developer portal.
How to Sign an iOS App
To sign an iOS app, you need a signing certificate and a provisioning profile. The signing certificate is used to sign the app, and the provisioning profile is used to specify the devices on which the app can run.
Once you have the signing certificate and the provisioning profile, you can sign your app using Xcode. Simply open your project in Xcode, select your target, and go to the General tab. Under the Signing section, select your signing certificate and provisioning profile.
