Fix 4a7fc95 by updating SwiftState to v1.1.1

Continuing #11, #12, #13, #14.

This pull request will fix `carthage build` = `xcodebuild -workspace XXX -sdk iphoneos ...` failure (error log in #13)
which **sometimes** selects `SwiftState-OSX` build-scheme which eventually requires iOS-CodeSign.

See https://github.com/ReactKit/SwiftState/pull/12 for more info.

By the way, adding `LD_RUNPATH_SEARCH_PATHS=$(PROJECT_DIR)/Carthage.build/Mac (or iOS)` for XCTest-targets will link to `Carthage.build` frameworks, and will also be runnable from xcodeproj (not needed for xcworkspace)
