xcode .dynamicType 已弃用。使用'type(of ...)'代替

.dynamicType is deprecated. Use 'type(of ...)' instead

提问by Rodrigo

I've just updated to Xcode 8 and iOS 10 (using legacy Swift Language Version).

我刚刚更新到 Xcode 8 和 iOS 10（使用旧的 Swift 语言版本）。

Trying to compile again my project has been an agony, even still using the old Swift syntax. This time one of my functions uses NSBundle(forClass: self.dynamicType)but now appears that .dynamicTypeis deprecated and Xcode doesn't even want to compile it.

尝试再次编译我的项目一直很痛苦，即使仍然使用旧的 Swift 语法。这次我的一个函数使用NSBundle(forClass: self.dynamicType)但现在似乎.dynamicType已弃用，Xcode 甚至不想编译它。

His suggestion is to use type(of: self)but that fails as well. Anyone knows the solution? Thanks.

他的建议是使用，type(of: self)但这也失败了。有谁知道解决方案？谢谢。

@dfri answer works perfectly for Swift 3.

@dfri 答案非常适合 Swift 3。

Regarding Swift 2.3, my solution was to clean Xcode (Command+Option+Shift+K) and delete everything in ~/Library/Developer/Xcode/DerivedData. The problem doesn't disappear instantly but after some time it will stop giving that error.

关于 Swift 2.3，我的解决方案是清理 Xcode (Command+Option+Shift+K) 并删除~/Library/Developer/Xcode/DerivedData. 问题不会立即消失，但一段时间后它会停止给出该错误。

Maybe it's a bug, after all we are in 8.0. I hope it gets fixed in next releases.

也许这是一个错误，毕竟我们是在 8.0 中。我希望它在下一个版本中得到修复。

Thank you everyone.

谢谢大家。

(The below holds for Swift 3; not legacy Swift Language Version (2.3), however, so it doesn't answer the OP's question, but could be valuable for Swift 3 users, nonetheless)

（以下适用于 Swift 3；但不是旧的 Swift 语言版本 (2.3)，因此它没有回答 OP 的问题，但对于 Swift 3 用户来说可能很有价值）

As noted in your question, dynamicTypeis now (Swift 3) deprecated in favour of type(of:). In addition:

正如您在问题中所指出的，dynamicType现在（Swift 3）已被弃用而支持type(of:). 此外：

• NSBundlehas been renamed to Bundle.
• The init(forClass:)initializer of Bundlehas been renamed to init(for:).

• NSBundle已更名为Bundle.
• 的init(forClass:)初始值设定项Bundle已重命名为init(for:).

Taking these changes into account, For Swift 3 you initialize (or fetch an existing instance associated with the specific class) your Bundleobject in the following manner:

考虑到这些更改，对于 Swift 3，您可以Bundle通过以下方式初始化（或获取与特定类关联的现有实例）您的对象：

class Foo {
    func bar() -> () {
        let bundle = Bundle(for: type(of: self))
        // ...
    }
}
