尝试检索提供程序的数据时，如何解决“无法调用非函数类型[UserInfo]的值”的问题？

Question

I'm trying to retrieve the FirebaseUser provider's data, but Swift debugger is returning the error

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

as can be seen in my code in the picture below:

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 = .....
        }
    }
}

Can someone tell me what's wrong?

Answer 1

providerData is an array property of FIRUser check Here , that you can't use { after it , so you need

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 = .....
    }
}
