Linting a swift iOS pod raises code sign errors without a certificate

[kylef]

Is it possible to not code sign when linting? Otherwise it will be difficult listing Swift iOS pods on travis etc where we don't have a certificate.

$ bundle exec pod lib lint URITemplate.podspec

 -> URITemplate (0.1.0)
    - WARN  | The URL (https://github.com/kylef/URITemplate.swift) is not reachable.

[!] URITemplate did not pass validation.
You can use the `--no-clean` option to inspect any issue.

Code Signing is required for Cocoa Touch Frameworks, otherwise the xcodebuild for the generated framework target won't succeed, at least that's my last info.

It is required when building for the device, but not when building for the simulator.

So linting should specifically build against a simulator architecture for iOS?
