Question

当我尝试显示另一个窗口时，我从Main.storyboard加载windowController并从MiaPlayerViewController.xib加载viewController;

我的这段代码在调试环境下运行良好，

当由OS X 10.13.x的设备归档时，也可以，

但是当我通过OS X 10.14.4的设备归档此代码时，它就会崩溃。

    // MiaPlayerWindowController is a NSWindowController 
    // MiaPlayerViewController is a NSViewController
public class func windowController() -> MiaPlayerWindowController {
    let storyboard = NSStoryboard(name: "Main", bundle: nil)
    guard let wc = storyboard.instantiateController(withIdentifier: "MiaPlayerWindowController") as? MiaPlayerWindowController else {
        NSLog("Error")
        return MiaPlayerWindowController()
    }
    let player = MiaPlayerViewController()
    // code is ok by here
    wc.contentViewController = player     // <- crash here
    wc.window?.animationBehavior = .none
    return wc
}

一些崩溃报告在这里
