Xcode (11.3.1) is having issues to found x86_64 architecture symbols while using XCFrameworks. The problem is that the architecture is inside the XCFramework, but first let me show you how the framework was created.
To generate the XCFramework I made two Archives:
- For iOS:
xcodebuild archive -scheme MyPod -target MyPod -destination="iOS" -archivePath build/ios.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphoneos SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES
- For iOS Simulator:
xcodebuild archive -scheme MyPod -target MyPod -destination="iOS Simulator" -archivePath build/iossimulator.xcarchive -derivedDataPath /tmp/iphoneos -sdk iphonesimulator SKIP_INSTALL=NO BUILD_LIBRARIES_FOR_DISTRIBUTION=YES
Then I generated the XCFramework:
xcodebuild -create-xcframework -framework ./build/ios.xcarchive/Products/Library/Frameworks/MyPod.framework -framework ./build/iossimulator.xcarchive/Products/Library/Frameworks/MyPod.framework -output xcframework/MyPod.xcframework
Here is the XCFramework created where we can see the two architectures: XCFramework preview
Once it was created, I distributed it by Cocoapods (1.9.0.beta.3). So my .podspec looks like:
s.subspec "Vendored" do |framework|
framework.vendored_framework = 'xcframework/MyPod.xcframework'
Then I consumed it in another project, and when compiling, it fails because it can't find the architecture for the simulator (on devices it works)
The log I got is the following:
ld: warning: ignoring file /Path/To/MyProject/Pods/MyPod/xcframework/MyPod.xcframework/ios-armv7_arm64/MyPod.framework/MyPod, missing required architecture x86_64 in file /Path/To/MyProject/Pods/MyPod/xcframework/MyPod.xcframework/ios-armv7_arm64/MyPod.framework/MyPod (2 slices) Undefined symbols for architecture x86_64: "_OBJC_CLASS_$MyPod", referenced from: objc-class-ref in SomeClass.o ld: symbol(s) not found for architecture x86_64
It looks like xcodebuild always go to the
ios-armv7_arm64 folder instead the
ios-i386_x86_64-simulator one, any ideas?
