Summary:
The same Keychain API calls fail when run in the Simulator in Xcode 9 in unhosted unit tests, but succeed in hosted unit tests, and they succeed in both cases on Xcode 8.
Steps to Reproduce:
- Install both Xcode 8.3.3 and Xcode 9.0.
- Clone repository from https://github.com/apontious/Secrets.
- Download and install iOS 9.0, 9.2, 10.0, and 10.2 SDKs.
- Open Xcode 8.3.3.
- Open Secrets project and test (Cmd-U) on all downloaded SDK versions. All tests succeed on all SDK versions.
- Close Xcode 8.3.3 and the 8.3.3 Simulator.
- Open Xcode 9.
- Open Secrets project and test (Cmd-U) on all downloaded SDK versions, and on the iOS 11 SDK included with Xcode 9.
Expected Results:
- All tests succeed on all SDK versions.
Actual Results:
- Despite being exactly the same test running on exactly the same downloaded Simulators, only the tests on the iOS 9.* SDKs and the hosted tests on iOS 10 and 11 SDKs succeed under Xcode 9.
Under Xcode 9, the iOS 10.* SDKs with the unhosted tests fail with the error -34018 ("A required entitlement isn't present").
Under Xcode 9, the iOS 11 SDK with the unhosted tests fail with the error -50 ("One or more parameters passed to a function were not valid").
Version/Build:
Xcode 9.0 with iOS 9.*, 10.*, and 11 SDKs.
Configuration:
macOS Sierra 10.12.6

Apple Developer Relations response on 10/9/2017:
APIs need to run in a properly entitled process, i.e. "hosted" in the terminology used.
