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

Question

我为几个需要跟踪的VC制作了一个BaseTrackingViewController。代码是用最新的xcode测试版和开发版本构建的。在iOS 14.5模拟器和iOS 15.0公测版的真实iPhone 11 Pro上运行。跑步非常完美。

在appcenter中取消编译
出现错误

这是基本的UIViewController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：

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()
}

创建了一个变通方案，以了解视图控制器何时"关闭"；被驳回"；由用户执行。由于在视图控制器上执行dismisse操作导致导航堆栈被清除。就我而言，这是不可取的。

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将重新构建。xcode测试版和实时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

发现故障

的解密

func viewDidUnload() { 
....
}

与appcenter编译器对viewDidUnload的旧声明(自iOS 7.0以来已弃用并已删除(相冲突。重命名它修复了的问题
