同时访问<地址>,但修改需要独占访问 [英] Simultaneous accesses to <Address>, but modification requires exclusive access
问题描述
我想在函数 myFunc
中指定用于操作的数组属性,但出现此错误.这是我的代码草图.
I want to specify the property which is an array for manipulation in the function myFunc
, but I am getting this error. Here is my code sketch.
self.data = MyObject()
func myFunc(x: inout [Int], y: inout [[Int]]) {
//manipulation code to x and y
}
myFunc(x: &self.data.array1, y: &self.data.array2)
myFunc(x: &self.data.array3, y: &self.data.array4)
知道如何使它工作吗?对于这个用例,我应该使用更好的模式吗?感谢提前!
Any idea how to make it work? Is there a better pattern I should use for this use case? Thx for advance!
推荐答案
在 Swift 文档中有非常详尽的解释:
Very thoroughly explained in the Swift documentation:
https://docs.swift.org/swift-book/LanguageGuide/MemorySafety.html
基本上,您威胁要同时以两种不同的方式对同一对象进行变异/写入.这是不连贯的,如果编译器不阻止你,运行时就会.
Basically you are threatening to mutate / write to the same object in two different ways simultaneously. That’s incoherent and if the compiler doesn’t stop you the runtime will.
