Integrating apollo-ios-xcframework using bazel throws errors

Question

Hi Apollo Team,

I’m working on upgrading apollo-ios-xcframework from v1.18.0 to v2.0.2 in our project, which uses Bazel to fetch and build the framework. During the process, I’m encountering several errors related to the use of @_spi, for example:

error: protocol requirement 'init(_dataDict:)' cannot be declared '@_spi' without a default implementation in a protocol extension

I noticed that swiftLanguageMode in your Package.swift now includes both Swift 5 and 6. Our project is still using Swift 5, and I wanted to check whether this might be the reason for the errors, or if there’s a recommended Swift version for Apollo xcframework v2.x.

Any guidance on required Swift version compatibility or how to resolve these errors would be greatly appreciated.

Thank you!

Hi @reshumalik-afk - none of us have any experience with Bazel unfortunately. Apollo iOS 2.0 is compatible with both Swift 5 and 6 so that shouldn't be an issue. To help with debugging can you please create a project that reproduces the build error, it'll be easier to work from that.

@reshumalik-afk We've come up with a solution for this. We'll be releasing a new version of apollo-ios-xcframework soon that makes the fix.

We don't and have never formally supported library evolution. It's not really necessary since we release open source code. You can always recompile it yourself. But all Apple's documentation said that to create a framework we needed to have BUILD_FOR_DISTRIBUTION=YES, which requires library evolution support to be turned on.

Recently I discovered this thread, and there is a mostly undocumented flag -allow-internal-distribution that allows you to build a framework without library evolution support.

So we'll be updating the makefile commands in the apollo-ios-xcframework repo.
