推荐答案

这是Xcode 7中的错误，如所述 HERE .上面写着:

It is a bug in Xcode 7 as mentioned HERE. Which says:

摘要:

在Xcode 7 GM之前，返回UITextInputMode.activeInputModes() UITextInputMode实例的数组.但是，在Xcode 7 GM中， 头文件和文档中的方法签名指出 返回一个字符串数组，这是不正确的.结果，代码 正确使用activeInputModes的文件将不再编译，并且 尝试在操场上使用activeInputModes会抛出一个

Prior to the Xcode 7 GM, UITextInputMode.activeInputModes() returned an array of UITextInputMode instances. However, in the Xcode 7 GM, the method signature in the header file and documentation states that it returns an array of Strings, which is incorrect. As a result, code that uses activeInputModes correctly no longer compiles, and attempting to use activeInputModes in a Playground throws an exception.
