😰 Signing problem

fastlane scan with default settings is success at local machine, but it is failed at bitrise.io by signing certificate error:

❌  error: No signing certificate "Mac Development" found: No "Mac Development" signing certificate matching team ID "XXXX" with a private key was found. (in target 'Tests')

This problem happens because Mac Developer certificate is tied to your machine, not CI machine.

😄 Solution

Use Developer ID Application certification explicitly to solve this problem.

Step 1: Use Developer ID Application

At general tab of project setting, disable automatic signing and use "Developer ID Application" for release:

Use same setting for Tests target.

Step 2: Upload private key to bitrise

Export "Developer ID Application" certificate from Xcode accounts preference:

Set strong enough password:

Upload exported p12 file to bitrise in the app's Workflow Editor, and set password:

Step 3: Run test with release configuration

Run tests with release configuration.

If you uses fastlane scan, write Scanfile like:

workspace 'EmojiIM.xcworkspace'
scheme 'EmojiIM'
configuration 'Release'

Step 4: Setup bitrise to use fastlane

Sometime, codesign command failed with "code object is not signed at all" error.

I don't understand detail, but Stack Overflow recommends to use --deep flags and solve this.
