1. What does the error mean?
The error occurs because the binary file in your app contains incomplete bitcode, which is no longer supported in the latest versions of Xcode. Starting with Xcode 14, Apple deprecated bitcode and completely removed its support in Xcode 16.
2. What is Bitcode?
Bitcode was an intermediate representation of the app binary code used by Apple to optimize and recompile apps for different devices and architectures. Apple has now shifted away from bitcode, making its inclusion in binaries unnecessary.
3. Why am I seeing this error now?
You are likely using a framework, library, or SDK (like Flutter, LivePerson, Didomi, etc) that still includes bitcode in its binaries. Since Xcode 16 no longer supports bitcode, these binaries are flagged as invalid when you attempt to archive or upload the app.
4. How can I fix this issue?
To resolve the issue, you need to remove or update the bitcode in the problematic binaries. Here’s how:
Option 1: Ask the SDK Provider to Update Their Framework
Contact the SDK provider (e.g., Flutter team, Didomi Team, etc ) and request an updated version of their framework that removes bitcode from the binaries.
Option 2: Manually Fix the Problem
