StoreKit：从 Swift 1.2 转换为 Swift 3 时出错
StoreKit: Error in converting from Swift 1.2 to Swift 3
我得到了一个示例项目来学习如何使用 Apple 的 StoreKit，这样我就可以学习将自动续订订阅服务应用到我的应用程序和任何应用程序内服务。
问题是示例项目来自 Swift 1.2 并将其转换为 Swift 3，我遇到了几个错误，但我遇到了 2 个警告和 2 个错误。希望有人能帮助我。
此外，在将代码转换为 Swift 3 时，代码仍然有效吗？既然老了？应用内购买是否有任何重大变化？

第一个函数中的两个问题都来自 before Swift 3，NSArrays 是在没有泛型类型的情况下导入的（即 [Any]，而不是 [SKProduct]）。
只需删除 as? SKProduct 部分即可修复警告，但在一次调用中添加所有内容会更清晰：
// Old
for i in 0 ..< products.count
{
self.product = products[i] as? SKProduct
self.productsArray.append(product!)
}
// New:
productsArray.append(contentsOf: products)
错误是因为虽然 response.products 和 response.invalidProductIdentifiers 最初是作为 [Any] 导入的，但现在输入了它们（[SKProduct] 和 [String]）。最简单的解决方案就是直接使用数组：
// Old:
products = response.invalidProductIdentifiers
for product in products
// New:
for product in response.invalidProductIdentifiers
因为它只是打印，我可能直接打印数组。
第二个函数的错误是因为编译器需要知道变量应该是什么类型的数组。从名称来看，我猜它应该是一个 [String]，但它没有被使用（正如同一行上的警告所指示的），所以你也可以删除该行。
