Apple Developer Certificate

Step 1: Verify Existing Code Signing Identity

Run the following command in Terminal to check if a development certificate already exists:

security find-identity -v -p codesigning | head -1 | cut -d\  -f 5-

  • If a certificate name is returned → proceed to the next step.

  • If the result is empty → create a new Apple Development certificate.

  • Open Xcode.

  • Navigate to Xcode → Preferences from the top menu.

  • Select the Accounts tab.

Step 2: Create Apple Development Certificate (If Not Available)

  • Open Xcode.
  • Navigate to Xcode → Preferences from the top menu.
  • Select the Accounts tab.
  • Click the + icon (bottom-left) and choose Add Apple ID (if not already added).
  • Sign in using your Apple ID credentials.
  • Select your Apple ID and associated Team from the right panel.
  • Click Manage Certificates.
  • Click the + icon (bottom-left).
  • Select Apple Development.
  • Click Done.

Step 3: Verify Certificate in Keychain

  • Open Keychain Access from Launchpad.
  • Select Login under Default Keychains.
  • Click My Certificates.
  • Confirm that the Apple Development certificate appears in the list.

If the certificate is not trusted, download the appropriate certificate from the Apple Developer portal and install it manually.
