ios - [String] 常量发生内存泄漏

Question

我有一个非常简单的 Swift 类，它只有一个静态方法，该方法分配 3 个字符串数组，并通过附加这些数组中的元素来创建一个随机字符串。

代码如下:

public static func generateText() -> String {

   let phraseComponent1 = [
        "Line 1,",
        "Line2,",
        "Line3,",
        "Line4,",
        "Line5,",
        "Line6,"]

   let phraseComponent2 = [
        "Line 1,",
        "Line2,",
        "Line3,",
        "Line4,",
        "Line5,",
        "Line6,"]

   let phraseComponent3 = [
        "Line 1,",
        "Line2,",
        "Line3,",
        "Line4,",
        "Line5,",
        "Line6,"]

    let componentIndex1 = Int(arc4random_uniform(UInt32(phraseComponent1.count)))
    let componentIndex2 = Int(arc4random_uniform(UInt32(phraseComponent2.count)))
    let componentIndex3 = Int(arc4random_uniform(UInt32(phraseComponent3.count)))

    let phrase1 = phraseComponent1[componentIndex1]
    let phrase2 = phraseComponent2[componentIndex2]
    let phrase3 = phraseComponent3[componentIndex3]

    return "\(phrase1) \(phrase2) \(phrase3)"
}

正如您在屏幕截图中看到的那样，此代码在第一个数组上生成了内存泄漏:

谁能告诉我原因吗？以及如何解决这个问题

我按照@werediver提到的那样做了，添加了一个巨大的循环来调用这个方法，并且堆没有移动，也没有泄漏的数量，所以正如他提到的，这是一个误导性的诊断。无需采取任何行动。
