Error "segment Use of private header from outside its module: 'netinet6/in6.h'"

[aadeshAvoma]

After updating the Xcode to v26.4. The segment library is thrown an error.

The reachability file accessing the private header

analytics-ios/Segment/Classes/SEGReachability.m

Line 26 in 4b09689

#import <netinet6/in6.h>

Please suggest the solution for this ?

For now I am downgrading my Xcode version to unblock.

Noticing same issue as well

We're having the same issue

[natanrolnik]

I've opened a PR fixing this issue.

If anyone wants to be unblocked before this gets merged or a new version tagged:

// In package dependencies:
.package(url: "https://github.com/natanrolnik/segment-analytics-ios.git", branch: "fix-reachability-private-header"),

// In target dependencies:
.product(name: "Segment", package: "segment-analytics-ios"), 

Notice the different package name (segment-analytics-ios instead of just analytics-ios)

Analytics (4.1.8)

@natanrolnik is it fixed for cocoapods or am I missing out something, I recently moved to Xcode 26+ version and it started coming

For me its happening via cocoapods for the same latest version.

I fixed for another cocoapod dependency here doing it like this in the Podfile:
(I adapted from my solution, so some values for file path may be wrong here, use the logs to make sure it works for Segment Analytics lib)
