After installing Xcode 10.1, I had trouble even with Carthage 0.31.2. But I also have a habit of deleting all simulators when installing Xcode major versions. Adding a simulator for iOS 12.1 fixed things.

安装 Xcode 10.1 后，即使使用 Carthage 0.31.2 我也遇到了麻烦。但我也有安装Xcode主要版本时删除所有模拟器的习惯。为 iOS 12.1 添加一个模拟器修复了一些问题。

Just upgrade your Carthage.

只需升级您的迦太基。

As indicated in other answers the cause behind this is that a key indicating simulator model availability changed in a recent update to Xcode 10.x. It was

正如其他答案中所指出的，这背后的原因是在最近的 Xcode 10.x 更新中，指示模拟器模型可用性的键发生了变化。它是

"availability" : "(available)",

and it is now

现在是

"isAvailable" : true,

Upgrading Carthage to 0.33.0 fixes this.

将 Carthage 升级到 0.33.0 解决了这个问题。

Using brew, enter the following to update Carthage

使用 brew，输入以下内容更新 Carthage

brew upgrade carthage

Notice the word is upgrade, not update.

注意这个词是upgrade，而不是 update 。

Check the version of carthage

检查迦太基版本

brew list --versions carthage

carthage 0.33.0

carthage 0.33.0

And in the terminal at the root of your project, enter this to rebuild your Carthage dependancies.

在项目根目录的终端中，输入此内容以重建您的 Carthage 依赖项。

carthage bootstrap --platform iOS

They all should build as expected.

他们都应该按预期构建。

You can check the data format of the available simulators through this command.
