Question

好的，所以我理解这个问题有点宽泛，但我不知道如何继续。

所以这就是我从面料看起来崩溃的原因（我无法重现这一点，但是我遇到了很多这样的崩溃事件）

对我而言，好像是这行在appdelegate启动时崩溃：

specialized static FFBaseApiService.accessTokenGetString.getter (FFBaseApiService.swift)

这是代码：

class var accessTokenGetString : String {
    return "?accessToken=\(currentUserAccessToken)"
}

class var currentUserAccessToken : String {
    return FFUserManager.sharedInstance.getUserAccessToken()
}

另外，我使用的是realm，getUserAccessToken看起来像这样：

func getUserAccessToken() -> String {
        if let user = user, let accessToken = user.accessToken {
            return accessToken
        }
        else {
            print("Returning empty access token")
            return ""
        }

    }

以这样的方式提取用户属性：

private var user : FFUser? {
    return realm.objects(FFUser.self).first
}

我没有任何想法，无论这里有什么不妥。任何人？

在libswiftCore.dylib _assertionFailed崩溃，不知道是什么导致了这一点
