Could Not Find Module 'Alamofire' for Target 'Arm64-Apple-Ios-Simulator'; Found: X86_64-Apple-Ios-Simulator, X86_64

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

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.

Another workaround is to set BuildSettings ->"Validate Workspace" to Yes. It will still show a warning, but will build the project.

Xcode 12 issue - Could not find module 'FrameworkName' for target 'arm64-apple-ios-simulator'; found: x86_64-apple-ios-simulator, x86_64

I fixed this by ensuring the build setting VALID_ARCHS (now appearing at the bottom of Build Settings in Xcode 12) contains "x86_64".

That is:

• Before I had: VALID_ARCHS = arm64, arm64e
• After fixing: VALID_ARCHS = arm64, arm64e, x86_64

(A little counterintuitive, as the error message says it couldn't find the module for arm64-apple-ios-simulator, :shrug:)

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

if you installed your pod using:

arch -x86_64 pod install

you should change it to:

pod install

after doing that you don not need to change your Excluded Architecture to arm64
