CarthageのBuild Failed ( Task failed with exit code 70 ) を解決する #iOS

環境

OS: macOS High Sierra v10.13.6
Xcode: v9.4.1(9F2000)
Carthage: v0.30.1
Swift: v4.1.2

errorの内容

carthage update や carthage bootstrap で一部ライブラリが失敗する。

出力の一部

Build Failed
    Task failed with exit code 70:

logの一部

xcodebuild: error: Unable to find a destination matching the provided destination specifier:

原因

Carthageで入れたいライブラリが見ている id(destination specifier) とXcodeのシミュレーターの id(destination specifier) が違う？

解決方法

結論から書くと ~/Library/Developer/CoreSimulator/Devices/ 配下をすべて消して、シミュレーターのリスト(?)を再構築すればOKです。

$ rm -rf ~/Library/Developer/CoreSimulator/Devices/*
$ carthage update --platform iOS

参考ページの手順にはPC再起動がありましたが、再起動せずに carthage update できました。Xcodeは再起動したほうがいいかもしれません。

失敗時の出力

詳細はログ /var/folders/vl/h60blwms4cv3g4f8v74fvcsc0000gn/T/carthage-xcodebuild.AYQcQq.log (h60blwms4cv3g4f8v74fvcsc0000gnの値は実行する度?に変わる)を確認してねと書いてあります。

logの内容

/var/folders/vl/h60blwms4cv3g4f8v74fvcsc0000gn/T/carthage-xcodebuild.AYQcQq.log の該当箇所。失敗した直後なら、一番下に書かれています。

xcodebuild: error: Unable to find a destination matching the provided destination specifier: とあります。なぜこうなったかは不明ですが、なにかが原因でおかしくなっているので、一度消してシミュレーターのリスト(?)を構築し直せば解決します。
