Update to iOS 9 error: i386 Unsupported architecture - ios

Question

I have a project which will generate framework.
My architecture setting is:
standard architecture(armv7, arm64)
i386
Valid architecture: armv7, arm64, i386.
In iOS 8.4, I can build it successfully without any problem.
However, when I update to iOS 9. I get "Unsupported architecture" error.
It looks like i386 is not supported, how can I make the framework which can be used in simulator?
Here is the error message:

Can someone help me to understand this and figure out this problem?

Answer 1

I also faces the same problem with Xcode 7.2 update. found a solution, Hope this helps for you,
Change script line which is used to build for simulator as follows,
xcodebuild -project ${PROJECT_NAME}.xcodeproj -scheme ${PROJECT_NAME} -sdk iphonesimulator -configuration ${CONFIGURATION} -destination 'platform=iOS Simulator,name=iPad' clean build CONFIGURATION_BUILD_DIR=${BUILD_DIR}/${CONFIGURATION}-iphonesimulator 2>&1

Answer 2

Just run into the same problem while trying to build a project from command line and solved the issue by setting -sdk parameter to iphonesimulator:
xcodebuild .... -sdk iphonesimulator ...

Answer 3

this didn't work for me, I had to also specify
PLATFORM_NAME=iphonesimulator

Answer 4

Select your project:
Under Build Settings > Architectures
Select Standard architectures - $(ARCHS_STANDARD)
