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 f

Answer 1

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.

If you want to automate the process for your project you can try the script below that I use in my framework projects.

It works for both Objective-C and the Swift projects. I tested on iOS and tvOS too.

For more detail and updates please follow my repo page.

Answer 3

Please check your Scheme be sure to run correct scheme.

And then you should open XCode > -Your Main Target- > Build Active Architecture Only and set 'NO' to build on the all architectures.

Options:

YES - If set to yes, then Xcode will detect the device that is connected, and determine the architecture, and build on just that architecture alone.

NO - If set to no, then it will build on all the architectures.

Answer 4

For me it was a setting missing. In Xcode go to: File->Workspace Settings . In Build System change it to "Legacy Build system".

Run it again and copy the new Framework

Answer 5

I have added two architectures i386 and x86_64. And set Yes to "Build Active Architecture Only". It works for me to build on every simulator devices.

For the XCode-12 Valid Architectures has been moved under User-Defined option at the very bottom as VALID_ARCHS

Answer 6

Swift 5.0-5.1, Xcode 11
Open Xcode, <your project>, Build Settings, Build Active Architecture Only and change to <NO> for Debug and Release. Architectures set/leave in Standard Architecture -$(ARCHS_STANDARD), important is next step:
Valid Architecture: armv7, armv7s, arm64, arm64e, ADD here x86_64 and if you need add i386 for Debug and Release. (String: armv7, armv7s, arm64, arm64e, x86_64)

Choose any simulator in your simulator list and BUILT IT. DONE. 

I hope it is works for you.

Description of Architecture:

armv64: iPhoneX, iPhone 5s-8, iPad Air — iPad Pro

armv7 : iPhone3Gs-5c, iPad WIFI(4th gen)

armv6 : iPhone — iPhone3G

-the above if for real devices

i386 : 32-bit simulator

x86_64 : 64-bit simulator
