How can I compile a library with Carthage using the latest beta version of Xcode?

Question

I am testing Swift 3 with Xcode 8 Beta (8S128d), which leads me to a situation where my libraries built in Carthage are not compatible with the source database.

Module file was created by an older version of the compiler; rebuild 'SwiftValidator' and try again Module file was created by an older version of the compiler; rebuild 'SwiftValidator' and try again .

How can I configure Carthage so that carthage update uses the Beta compiler on the standard?

Answer 1

I moved the beta to / Applications.

sudo xcode-select -s /Applications/Xcode-beta.app/ installs Xcode for use in beta.

carthage update --platform iOS --no-use-binaries creates libraries for iOS and prevents Carthage from loading existing (but incompatible) precompiled binaries.
