Question

我有代码：

static var default: Realm {
    do {
        return try Realm()
    } catch let error {
        try? FileManager.default.removeItem(at: Realm.Configuration.defaultConfiguration.fileURL!)
        return try! Realm()
    }
}

我稍后发布它后开始崩溃return try! Realm()。你能解释一下我的原因吗？下面我添加了崩溃日志。我们没有使用数据或使用它们的代码更改任何内容。我们所做的只是更新Realm pod。
