Allow warnings when building Podspecs (#274)
Allow warnings when building Podspecs (#274)

Motivation:

When pushing Cocoapods a warning is emitted for SwiftNIOSSL
('SecTrustEvaluateAsync' was deprecated in watchOS 6.0). Pushing the
pods fails as a result.

Modifications:

Allow warnings when pushing pods.

Result:

Pods can be pushed with warnings.
