thanks for your new SDK update (v6.3.5)!

Our app is unfortunately not yet supporting Xcode 11. When I attempt building with SFMC 6.3.5, I get this error ":-1: Undefined symbol: ___isPlatformVersionAtLeast".

  • Is it possible to build the latest version of the SDK with Xcode 10.2.1?
  • Could 6.3.4 still support iOS 13 pushes? (Pushes stopped working on iOS 13 w/ SDK v6.2.2)

    Welcome to SFSE! Just to be clear, most of us here aren't directly employed by Salesforce, but rather work with Salesforce as part of our day-to-day jobs. You might find someone else here that has a workaround, but if you're looking for official support then you should probably go through help.salesforce.com/support

  • @DerekF is right, but some of us monitor the boards and contribute where we can :)

We have discovered a build issue and are correcting the MobilePush SDK iOS version and will be releasing a v6.3.6 as soon as possible.

Please check our main docs page at https://salesforce-marketingcloud.github.io/MarketingCloudSDK-iOS/ for updates.

  • The update was published and pushed yesterday; the SDK will now build correctly. Sep 27, 2019 at 18:53
