Update to Alamofire 4.0 and Swift 3.0 via Carthage

问题

I am trying to update Alamofire to version 4.0. When I run carthage update I get many errors when building Alamofire scheme. It looks like files weren't updated to Swift 3.0 syntax. What I am doing wrong? Log from terminal:

*** Checking out Alamofire at "4.0.0"

....... and many others

I am using carthage version 0.18. I tried delete carthage Build and Checkout folders. I have set Xcode 8 version as default. For now without any luck.

回答1:

The problem was that in terminal default Xcode was still 7. I checked it by command:

xcodebuild -version

which returns:

Xcode 7.3
Build version 7D175

In system it looks like default is Xcode 8.0 but not in terminal. So I use command:

sudo xcode-select -switch /Applications/Xcode\ 8.app/

And now it's working.
