With Xcode there are various configuration and manual steps required for submitting an app to the App Store Connect portal. In this post, we will explore how to code sign iOS apps and publish them to the App Store.įirst, we will cover the iOS app distribution method using Xcode and and then Codemagic. There are various security terms involved in the process of code signing, such as public key, private key, certificates, and digital signatures.Ĭode signing on Apple platforms, including iOS, relies on public-key cryptography based on the X.509 standard. Code signing is the process of digitally signing any form of the code to confirm the author of the code and guarantee that the code has not been changed or corrupted since it was signed. Unless the device is jailbroken, all the apps that run on iOS devices need to be signed by trusted developers who have a valid certificate from Apple. We also recommend you read iOS Code Signing and Publishing with codemagic.yaml file. The best part is that you do not need to have a macOS machine!
