No Such Module Unity Framework, After updating to Xcode 16.3 from Older Version.

[harshith30]

I followed the example and was able to integrate the Unity and deploy it in the AppStore (Year 2022), but after updating my Xcode from version 14.3 to Xcode 16.3, i'm facing no such module 'UnityFramework' error.

What I Know So Far:

I don’t know the Unity version (the project was built in 2021-2022). The Unity project still runs on its own after I removed -mno-thumb from its target’s build settings even in the latest Xcode version (16.3).

As it was working till the Xcode version 14.3, i have not changed any code relevant to Unity.

What I’ve Tried:

a. Added UnityFramework.framework to “Link Binary with Libraries” and marked it as “Embed & Sign”.

b. Verified Framework Search Paths include $(PROJECT_DIR)/UnityProject/build/Debug-iphoneos

c. Cleaned build folder, deleted Derived Data

d. Checked [CP] Embed Pods Frameworks step in Build Phases

Request for Help:

Has anyone encountered this issue post-Xcode 16.3 update from 14.3 . I’d really appreciate any guidance, updated workflows, or even a checklist of steps for properly integrating Unity into an existing iOS app with the new Xcode build system.

In my case, I had to reset the target SDK. I was trying to run it on the simulator, but it was set to a physical device, which caused the error. I’m using Apple Silicon, and the problem was that it was set to x86. I’m using Unity 6 and Xcode 16.4.

How did you solve it? I have the same problem. I integrated Flutter with Unity and built it according to the documentation. The error message is No such module 'UnityFramework'

I don't have this problem, I followed every detail of the readme file, it worked well for me. just one thing to point out, you are using Swift in your project (which is most up to date way) . but this project is compatible with Objective C as far as I am aware.

I'm using 16.0 and haven't had any issues, it's okay to use a Swift project @Irashad you just need to know how to convert what you need to Swift. I converted what I needed from this project to my iOS project which is all Swift and SwiftUI and I haven't had any issues. @harshith30 ensure you created your workspace and changed the Data folder to target UnityFramework not the Unity-iPhone. This repo is a bit out of date but I haven't had issues with any of the latest Xcode or Swift.
