Appcenter在从UIViewController实现自定义基类后不会构建iOS

Question

我为几个需要追踪的VC做了一个BaseTrackingViewController。代码是使用最新的xcode-beta和开发版本构建的。在模拟器iOS 14.5和带有iOS 15.0公测版的真实iPhone 11专业版上运行。跑步很完美。

直到在appcenter中编译

以下错误

下面是UIViewController基类

class BaseTrackingViewController: UIViewController {
    var screenName: String { return String.empty }
    lazy private var trackingProperties: [String: MixpanelType] = ["SCREEN_NAME": screenName]
    var customTrackingProperties: [String: MixpanelType]?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        let properties = customTrackingProperties != nil ? mergeDictionaries(trackingProperties, customTrackingProperties!) : trackingProperties
        trackEvent(event: "LOADED", properties: properties)
    }
    
    func viewDidUnload() {
        trackEvent(event: "DISMISSED", properties: trackingProperties)
    }
    
    override func dismiss(animated flag: Bool, completion: (() -> Void)? = nil) {
        super.dismiss(animated: flag, completion: completion)
        viewDidUnload()
    }
    
    func trackEvent(_ event: String, properties: [String: MixpanelType]) {
        let properties = mergeDictionaries(trackingProperties, properties)
        trackEvent(event: event, properties: properties)
    }
    
    private func trackEvent(event: String, properties: [String: MixpanelType]) {
        Mixpanel.mainInstance().track(event: event, properties: properties)
    }
    
    private func mergeDictionaries(_ dict1: [String: MixpanelType], _ dict2: [String: MixpanelType]) -> [String: MixpanelType] {
        return dict1.merging(dict2){(_, second) in second}
    }
}

基类的实现方式如下所示：

class RandomViewController: BaseTrackingViewController, DeltaChangedDelegate {
    
    override var screenName: String  { return "PersonalSummary" }
    var delta = 0
    var deltaDelegate: DeltaChangedDelegate?
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        deltaDelegate = self
    }
    override func viewDidLoad() {
        // to track something extra when initialized
        customTrackingProperties = ["DELTA": delta]
        super.viewDidLoad()
    }
    func doSomething() {
        trackEvent("SomeEvent", properties: ["SomeProperty": "SomeValue"])
    }
    func onReceiveDeltaChanged() {
        trackEvent("LOADED", properties: ["DELTA": delta])
    }
}
protocol DeltaChangedDelegate: AnyObject {
    func onDeltaChanged()
}

创建了一个变通方法，以了解何时视图控制器被用户“解除”。因为关闭视图控制器本身会导致导航堆栈被清除。这在我的情况下是不可取的。

class RandomNavigationController: UINavigationController {
    override func popViewController(animated: Bool) -> UIViewController? {
        if let vc = super.popViewController(animated: animated) as? BaseTrackingViewController {
            vc.viewDidUnload()
        }
        return nil
    }
}

当删除所有这些代码及其实现时，appcenter会再次构建。在xcode-beta和实时xcode应用程序中没有编译器错误。尚未对项目或目标设置或包进行任何更改

Answer 1

找到故障

的声明

func viewDidUnload() { 
    ....
}

与使用appcenter编译器的旧的viewDidUnload声明(从iOS 7.0起已弃用并删除)冲突。重命名解决了这个问题
