Pod install fails for versions after 1.0.3 due to VersionChecker.swift

Bug report

Installing Apollo via Cocoapods for versions after 1.0.4+ fails due to an issue with a file VersionChecker.swift. I checked the commits and it looks like this file was added 8 days ago before v1.0.4 was released. Installing a previous ver worked fine.

This is the error message:

/Users/y/Library/Caches/CocoaPods/Pods/Release/Apollo/1.0.4-7c977/Sources/CodegenCLI/Extensions/VersionChecker.swift:34:29: error: variable binding in a condition requires an initializer
      if let projectRootURL {
                            ^

Hi @yiyingzz - if let projectRootURL { is the new if let shorthand from SE-0435. From that proposal you can see that it was implemented in Swift 5.7, which is available in Xcode 14.0/14.1. If you update your version of Xcode the compiler error will go away.

Is there a specific reason you won't be able to update Xcode?

Hi @calvincestari - thanks for the quick response! I will have to check with our team if we can update it as we were on 13.x due to some build issues.
