使用通用类型数组作为参数的Swift编译器错误

Question

I am trying to do something simple: Passing objects of a particular class MyClass into a function like so

func addObjects<T:MyClass>(objects:[T]){
}

But I get a compiler error

<unknown>:0: error: unable to execute command: Segmentation fault: 11
<unknown>:0: error: swift frontend command failed due to signal (use -v to see invocation)
Command /Applications/Xcode6-Beta3.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift failed with exit code 254

If this truly is the compiler's fault, is there some workaround for this issue ?

Answer 1

Is that all of your code? This is working fine for me in Beta 3.

class MyClass{
}
func addObjects<T:MyClass>(objects:[T]){
}
addObjects([MyClass(), MyClass()])

Answer 2

func addObjects<T where T == MyClass>(objects: [T])

虽然当然您不需要泛型：

func addObjects(objects: [MyClass])
