Signing, Capabilities & Provisioning
Configure certificates and entitlements.
Signing, Capabilities & Provisioning is a free SwiftUI Academy lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the SwiftUI Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Why Signing Exists
Apple requires every app to be code signed. Signing proves the app came from you and has not been tampered with since. 🔐
Your Developer Account
Signing relies on an Apple Developer account. It links your apps, certificates, and identifiers to one verified identity.
Signing Certificates
A certificate is a private key Apple trusts. Your Mac uses it to stamp builds so devices and the App Store accept them.
The Bundle Identifier
Each app has a unique bundle identifier, like com.yourname.app. It is your app permanent name across Apple systems.
Provisioning Profiles
A provisioning profile ties your certificate, bundle ID, and allowed devices together so a build can install and run.
Automatic Signing
Turn on Automatically manage signing in the Signing and Capabilities tab, and Xcode creates the certificates and profiles for you.
Selecting Your Team
Pick your Team from the dropdown. Xcode then matches the right account and keeps signing settings in sync.
What Capabilities Are
A capability unlocks a system feature like push notifications or iCloud. You add it instead of editing config files by hand.
Adding a Capability
Click plus Capability, then pick a feature. Xcode updates your entitlements and provisioning so the feature works at runtime.
Entitlements
Behind the scenes, capabilities write into an entitlements file that grants your app permission to use protected features.
Keep Identifiers Stable
Never change your bundle identifier once you ship. Apple treats a new ID as a brand new app, losing your existing users.
Quick Check
Your build is configured to sign. One quick question about provisioning.
Recap
You set up code signing: a developer account, certificates, a bundle ID, provisioning profiles, and capabilities that grant special features. ✨
