问题
I cannot run my app on simulators anymore. Online suggested that I edit my project.pbxproj, but that does not appear to work. How do I reclaim the ability to run my project on my simulator (and remain able to do so on a device)? I am working on another project that uses many of the same frameworks, but it runs on a simulator. What would cause a similar framework to work in one project but not in another?
回答1:
Xcode 12.3
In my case I solved this problem by simply setting Validate Workspace to Yes in the Build Settings tab
回答2:
possible reason would be
- framework which you are using may not be built for simulator architecture(x86_64), you can check the compatibility by going to framework folder (framework_name.framework --> modules --->framework_name.swiiftModule-->) in this path you should see arm/i386/x86_64 support files
- if you have updated to new Xcode, the frameworks you are using are not compatible to the newer compiler version, so vendor needs to share the recent compatible one, in this case you will not be able to run on both device and simulator

For XCODE 12.3 the latest one - If you face this issue -
Here is a fix
Under Build Settings - Navigate to Validate Workspace - Change it to YES (By Default its NO)
回答4:
I suppose the framework you are linking was built only for arm architecture. You won't be able to run it in a simulator. You will need an author of the framework to build a "universal framework".

I needed to remove the framework then add it again, which also embedded it--which it wasn't before.

No doubt that the fix in case of Xcode 12.3 is to setup the Validate Workspace property in the target's build setting. However if you check the diff after this change, the reason of the build error is the missing parameter (VALIDATE_WORKSPACE) from the project file, not the value of the parameter. So you don't need the value to be YES. You need to add the value to the project settings and you can leave it on the default value (NO). At the first time, it shows up in the Build Settings with NO, but only because that is the default value of the missing parameter.
TLDR; Without changing your project setup, go to your target's build settings, find "Validate Workspace", set it to YES, then set back to NO.

Xcode 12.3 is full of issues. Your options are :
- Use legacy build system or
- Downgrade to 12.2 Not sure how Apple release such a buggy product
