Could not find module for target 'x86_64-apple-ios-simulator'

Question

I have my custom framework and it works properly in XCode 10. I rebuild it in XCode 11 beta 3, then integrated into the app, and get the following error:

Could not find module 'MyCustomFramework' for target 'x86_64-apple-ios-simulator'; found: arm64, arm64-apple-ios

Are there some changes I have to make in "valid architectures" in the framework project?

Updated: I can't pick any answer as a correct one as the framework in my case was really tiny (one class, a few methods) and almost not in use, so I decided to get rid of it and move these a few methods into main project.

To solve this issue I had to create a fat library of my custom framework again using xcode 11 tools.

To do that I did the following:

1) Build YourCustomFramework target for iOS simulator and extract framework from products folder on your desktop.

Xcode⁩ ▸ ⁨DerivedData⁩ ▸ ⁨Your Project ▸ ⁨Build⁩ ▸ ⁨Products⁩ ▸ ⁨Release-iphonesimulator

2) Build YourCustomFramework target for Generic iOS Device and extract framework from products folder on your desktop.

Xcode⁩ ▸ ⁨DerivedData⁩ ▸ ⁨Your Project ▸ ⁨Build⁩ ▸ ⁨Products⁩ ▸ ⁨Release-iphoneos⁩

3) Rename the simulator generated framework to YourCustomFramework-sim.framework so that it is distinguishable later.

4) Use the lipo command to combine both binaries into a single fat binary file. (cd to your desktop or wherever your custom framework file is located)

$lipo -create ./YourCustomFramework-sim.framework/YourCustomFramework ./YourCustomFramework.framework/YourCustomFramework -output ./YourCustomFramework

5) Copy YourCustomFramework binary file created in above step and replace it with the binary in YourCustomFramework.framework folder.

6) From folder

YourCustomFramework-sim.framework/Modules/YourCustomFramework.swiftmodule/

copy all of the modules and paste them to

YourCustomFramework.framework/Modules/YourCustomFramework.swiftmodule/

This should solve your issue.
