在Xcode10.2中将数组读写到文本文件的代码

let array = [1, 2, 3, 4, 5]
let filePath = "path/to/your/file.txt"

(array as NSArray).write(toFile: filePath, atomically: true)

if let loadedArray = NSArray(contentsOfFile: filePath) as? [Int] {
    // 成功读取数组
    print(loadedArray)
} else {
    // 读取数组失败
    print("Failed to load array from file.")
}
