ios - 尝试检索提供商数据时如何修复 "Cannot call value of non-function type [UserInfo]"？

Question

我正在尝试检索 FirebaseUser 提供程序的数据，但 Swift 调试器返回错误

Cannot call value of non-function type '[UserInfo]'

如下图我的代码可以看出:

let providData = userInstance.providerData {
    for profile in providerData {
        if profile.providerID == "facebook.com" {
            let fbUserId = profile.uid
            fbProfilePicUrl = "https://graph.facebook.com/\(fbUserId)/picture?height=300"
            self.profilePicUrl = fbProfilePicUrl
        }else if profile.providerID == "google.com" {
            let googleUserId = profile.uid
            //self.profilePicUrl = .....
        }
    }
}

谁能告诉我哪里出了问题？

providerData 是FIRUser 的一个数组属性检查Here , 你不能在它后面使用 { ，所以你需要

for profile in user.providerData {
    if profile.providerID == "facebook.com" {
        let fbUserId = profile.uid
        fbProfilePicUrl = "https://graph.facebook.com/\(fbUserId)/picture?height=300"
        self.profilePicUrl = fbProfilePicUrl
    }else if profile.providerID == "google.com" {
        let googleUserId = profile.uid
        //self.profilePicUrl = .....
    }
}
