Report

What did you do?

1. pod lib create NAME
2. Hit "enter" to accept all default values
3. In xcode, built newly made project

What did you expect to happen?

Project would build successfully.

What happened instead?

Project did not build successfully.
Specifically two swift compile "Overlapping access" errors with Nimble in Nimble/Carthage/..../CwlCatchBadInstruction.swift

Line 100: "Overlapping accesses to 'request', but modification requires exclusive access; consider copying to a local variable"
Line 124: "Overlapping accesses to 'reply', but modification requires exclusive access; consider copying to a local variable"

I need to admit my ignorance with iOS dev. To me this looks like a Nimble problem, not a CocoaPods problem. Maybe the most recent version of Nimble is borked? I couldn't say what this problem is for certain.

I googled and searched through the Issues and couldn't find a problem with a default pod lib create out of the box.

Yes this is a Nimble issue but you are also pointing to a very old version.

pod 'Nimble', '7.3.1'

In your Podfile and worked for me.

Thanks @dnkoutso. I'll update to the newest version. Why does create lib create a podfile that points to such an old version?

[dnkoutso]

@brianLeeson good question. It reads it from this repo https://github.com/CocoaPods/pod-template/blob/master/setup/ConfigureSwift.rb#L21.

You can open a PR there to update it!

@dnkoutso, I'll likely give it a shot!
