After pressing the button Build or Build and Run on Unity, an XCode project will be created.
In the case you are facing the following issue:
'/Users/hisplayer/Desktop/Test-Builds/iOS-2021/Frameworks/com.my.package/HISPlayer/Plugins/iOS/
HISPlayeriOS.framework/HISPlayeriOS' does not contain bitcode. You must rebuild it with bitcode enabled
(Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target.
file '/Users/hisplayer/Desktop/Test-Builds/iOS-2021/Frameworks/com.my.package/HISPlayer/Plugins/iOS/
HISPlayeriOS.framework/HISPlayeriOS' for architecture arm64
In order to solve this, please go to the UnityFramework Target > Build Settings, select All option and put the Build Options > Enable Bitcode to No as you can see in the following picture
