Compiler error with Xcode 10.2 (10E125) with Apollo cocoapod 0.9.5

[commanda]

Compiler error:

/Users/amanda/Playpen/Fresh/Pods/Apollo/Sources/Apollo/Collections.swift:65:42: Cannot assign value of type 'EnumeratedSequence<[Key]>.Iterator' to type 'EnumeratedSequence<IndexingIterator<Array<Key>>>.Iterator'

Repro steps:

• Update to Xcode 10.2 (10E125)
• Create a fresh Xcode project
• pod init
• Add pod Apollo to the Podfile
• pod install
• See that cocoapods installed Apollo (0.9.5)
• Open the .xcworkspace
• Attempt to compile the project
• See the compiler error

I tried setting the Swift language version to 4, 4.2, or 5, and also tried setting the same on the Apollo project, but I still got the compiler error.

Podfile:

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'Fresh' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Fresh
  pod 'Apollo'

end

[commanda]

When I point my podfile at the latest from master at github instead of using the most recent release, the compiler error is fixed.
pod 'Apollo', :git => 'https://github.com/apollographql/apollo-ios.git'
I think this means a new release is due?

Pointing to the master branch certainly works, but for me at least, it results in insanely slow compile times (from normally 15 seconds 👉 8-10 minutes). Now, I of course cannot say for sure that this is caused by Apollo specifically, but this is literally the only change I've made to get my project to compile in Xcode 10.2.

Yes, and pointing at master is never fun in the long run. It would really be great to have an official release that works with Swift 5!

We're waiting for Travis to update to Xcode 10.2, so we can land #475.

... The intricate dependency graph of the World Wide Web 😅

[musicdev20]

What's your ETA on this? I need this to work because I have a dependency that is failing. Thanks!

[jnutting]

If you're in a really tight spot, @GiantBlue76, you can either point at master or do a temporary local fix - just change the type of the variable that it's complaining about in the 0.9.5 code to match what the compiler expects. I did so, and everything worked just fine.

FIY Travis does support Xcode 10.2, I'm using it in graphql-community/ApolloAlamofire#3 test builds. I've just added created draft #491 in Apollo repository, but not sure how to start Travis build for that PR, can anyone help please?

[martijnwalraven]

@MaxDesiatov I don't think that is Xcode 10.2 final yet, see https://travis-ci.community/t/update-to-xcode-10-2-release/2809/2. As far as I know, that's why #475 is still failing.

Time to start using CircleCI perhaps? Travis has historically been quite slow in their support of new macOS/Xcode versions. CircleCI as of right now already supports Xcode 10.2!

[commanda]

@vandadnp Nope, CircleCI is still on beta 3 of Xcode 10.2. I'm waiting on them to get the GM too.

[vandadnp]

@commanda you're right. They didn't explicitly state that it's a beta but they did provide the build number of 10P99q which is in fact beta!

[vandadnp]

I contacted Travis' support and this is their reply:

Thank you for getting in touch!

We're hopefully aiming to have the GA version of Xcode 10.2 available by the end of the week. I'd recommend keeping an eye on https://blog.travis-ci.com/ as we'll most likely make an announcement when it's available.

Hopefully, this helps. Don't hesitate to get in touch if you have any questions or concerns. We'd be happy to help.

Sincerely,
Carla
