App Store 崩溃报告 EXC_BREAKPOINT (SIGTRAP)
App Store crash report EXC_BREAKPOINT (SIGTRAP)
下面是从 iTunes Connect 下载的崩溃报告，苹果人说 "We were unable to review your app as it crashed on launch"。
我知道 'EXC_BREAKPOINT (SIGTRAP)' 表示 a non-optional type with a nil value 或 a failed forced type conversion，我检查了第 0、1、2 和 41 行关注我的应用程序 属性、新安装和尝试从旧版本更新，全部在真实设备上，一切正常，没有崩溃发生。我不知道崩溃发生在哪里？
你能给我一些建议很有帮助。非常感谢！！！

下面是static ContentViewController.iphone.getter的代码：
在common.swift中定义：
enum iPhone: CGFloat {
case iPhoneSE = 568
case iPhone = 667
case iPhonePlus = 736
case iPhoneX = 812
init!(_ rawValue: CGFloat) {
self.init(rawValue: rawValue)
}
}
在ContentViewController.swift中定义：
static var iphone: iPhone {
let sceneHeight: CGFloat = UIScreen.main.bounds.height
if iPhone(sceneHeight) == .iPhoneSE {
return .iPhoneSE
} else if iPhone(sceneHeight) == .iPhone {
return .iPhone
} else if iPhone(sceneHeight) == .iPhonePlus {
return .iPhonePlus
} else {
return .iPhoneX
}
}
init!(_ rawValue: CGFloat) {
self.init(rawValue: rawValue) }
你在这里使用强制解包 init 但你有这样的情况，如果没有情况与传递的值对应，枚举可以 return nil。它可以是 iPad (768) 或 iPhone 4s (480)。所以你打开 nil 并且系统抛出异常。
