pod lint doesn't respect swift_version of dependencies

Report

What did you do?

Ran pod lib lint mypod

What did you expect to happen?

Dependencies with different versions of swift to compile with their respective versions and pass linting.

Per discussion here: #8897 (comment)

What happened instead?

Linting failed as it was using the swift version from the main Podspec to compile the dependencies

@sprynmr that is a confirmed bug. Will ship in 1.7.3.

The PR #8897 actually regressed it. Thanks again for filing.

[dnkoutso]

@sprynmr have you tried CocoaPods 1.7.1?

[bobspryn]

I haven't, but I will test it now.

[dnkoutso]

Fix #8941

[dnkoutso]

Confirmed in my change.

[bobspryn]

🎉

[bobspryn]

Confirmed 1.7.1 also does not have the issue.

[dnkoutso]

Cool.

[dnkoutso]

Will ship with 1.7.3 which also has some improvements for CDN in CocoaPods/Core.

[dnkoutso]

Shipped 1.7.3.
