Compilation error with Xcode 26 beta 1

Forum|alt.badge.img+3

I am trying to build my app with Xcode 26 beta 1. RevenueCat is generating errors:

For many functions, I’m getting this error.

“Concurrency is only available in iOS 13.0.0 or newer”

 

Here is an example of the code in Obsoletions.

    func paymentDiscount(for discount: SKProductDiscount,

                         product: SKProduct) async throws -> SKPaymentDiscount {

        fatalError()

    }

 

I am using RevenueCat 4.43.3

Is there a way I can avoid these errors - I am not ready to move to RC 5.x yet.

My code supports iOS 16 or later.

    Same here (4.43.4)

    Maybe we’ll need an SDK version that drops pre iOS 13 support?

    Can we get a fix for 4.x? I’m not ready to move to 5.x yet.

    Hi! Antonio here, from the RevenueCat’s CoreSDK team. Thank you for the report! Let’s try to pinpoint the cause of this so that we can work on a fix.

    I’ve tried to reproduce the compilation errors using Xcode 26 Beta 1 and I wasn’t able so far. I’ve created some sample projects from scratch using purchases-ios v4.43.6 and I could build them properly. I tried these combinations:

    • Set the minimum deployment version to iOS 16
    • Built and ran in multiple iOS simulators (including iOS 26, iOS 18 and iOS 16)
    • In Build Settings, set Swift Language Version to Swift 5 and also to Swift 6
    • Added RevenueCat with Swift Package Manager and also with Cocoapods

    and I didn’t encounter the build error mentioned in this thread.

    Could you share more details about when the issue happens?

    • What version of macOS are you using?
    • What are your build settings?
    • If you’re using Cocoapods, could you share the relevant sections of the Podfile?
    • Ideally, it would be extremely helpful if you could share a Sample project where the issue is reproducible.

    Happy to take a look once we have that info!

    Thanks Antonio for looking into the issue for SDK v4. I am encountering this issue myself on a legacy XCode project with base deployment of 15.0. However, when I try to recreate the issue from a fresh XCode project, the issue does not appear. 🤷

     

    I have “fixed” the issue by forking Package.swift to have a minimum iOS version support of 13.0.

    There may be unintended new checks with XCode 26 with Concurrency support, and the original minimum iOS 11.0 may no longer be allowed.
