Soo after almost 7 Hours Non stop if found the permanent solution.
1. Open your generated Unity-iPhone.xcworkspace in Xcode.
2. In the left sidebar, click on the UnityFramework target.
3. At the top, select the Build Settings tab.
4. In the search bar, type: Other Linker Flags
and delete these 2 From all the dubug release etc etc
* Removed -ld_classic
* Removed -weak-lSystem (because it’s invalid)
now clean project
and now
||1.|Select UnityFramework target.|
|---|---|---|
