Xcode is using a -Xlinker flag that libtool doesn't understand
I have a target that contains Objective-C source files and builds a static library for iOS. It works fine. I just tried adding a single Swift file to it, and now it fails to build, with a strange link-time error: libtool: unknown option character `X' in: -Xlinker which sounds like Xcode is using a command-line flag that libtool doesn’t understand. A bug in Xcode, maybe? (I’m using the latest beta of 6.3: 6D554n.) If I remove the .swift file from the target, it builds file. Re-add it, I get the error. I’ve checked the target build settings and there’s no custom “-Xlinker” flag defined, so this must be something Xcode came up with on its own. Here’s the entire command line generated by Xcode, and the entire error message: /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static -arch_only x86_64 -syslibroot /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.3.sdk -L/Couchbase/Seekrit/build/Seekrit/Build/Products/Debug-iphonesimulator -filelist /Couchbase/Seekrit/build/Seekrit/Build/Intermediates/Seekrit.build/Debug-iphonesimulator/SeekritIOS.build/Objects-normal/x86_64/SeekritIOS.LinkFileList -L/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/swift/iphonesimulator -Xlinker -add_ast_path -Xlinker /Couchbase/Seekrit/build/Seekrit/Build/Intermediates/Seekrit.build/Debug-iphonesimulator/SeekritIOS.build/Objects-normal/x86_64/SeekritIOS.swiftmodule -o /Couchbase/Seekrit/build/Seekrit/Build/Products/Debug-iphonesimulator/libSeekritIOS.a error: /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: unknown option character `X' in: -Xlinker ___ Do not post admin requests to the list.

Oops, I should have googled first. I found a discussion of this error from last June (right after the first Swift release): https://github.com/CocoaPods/CocoaPods/issues/2226 https://github.com/CocoaPods/CocoaPods/issues/2226 wherein someone quoted from the Xcode 6.0b2 release notes: It is not possible to build static libraries which contain Swift code in this release. (17181019)” Oops. Apparently this hasn’t been fixed yet? Good to know, since the main project I work on is primarily built as a static library :-p —Jens ___ Do not post admin requests to the list.

Since we now have frameworks on iOS and OSX and swift seems very framework-y, I don’t know if or when that will ever be fixed. ___ Do not post admin requests to the list. They will be ignored.
