This run script will build the iphoneos and iphonesimulator schemes and then combine them into a single framework using the lipo tool (including all the Swift module architectures). This version works with Cocoapods, merging simulator and device architectures for intermediate libraries as well. To use this script, go to Product > Scheme > Edit S…

Hello, I have a problem that unless Bitcode is set to NO the script does not generate the binaries for the simulator and if the bitcode is enabled when I add my framework to a test app I have an error that says bitcode was not enabled by the creator of this framework.

try to give answer to my STO question about creating framework from terminal.

no work in Xcode 9

The skip install is a vital step in this script, if its YES, the ${ARCHIVE_PRODUCTS_PATH} is /Library, and if it is NO, this is set to proper folder to get the framework. Checked on Xcode 9.

Kudos to author.

Can this be updated for Xcode 10?

Doesn't work in Xcode 10.

This does work for me in Xcode 9.4.1 but not Xcode 10. The cause of the issue seems to be a new build system in Xcode 10: https://developer.apple.com/documentation/xcode_release_notes/xcode_10_release_notes/build_system_release_notes_for_xcode_10

As a temporary workaround in Xcode 10, you can set the build system to 'Legacy Build System' in the File menu > Workspace Settings. I would not expect this setting to remain available forever.

@dmdeller there's also an Apple Dev Forum thread on that topic, with this comment down below showing an automated solution
