“无法打开文件__photo.jpg__,因为可以确定其内容的文本编码。”iOS Swift中的错误

我刚接触过iOS。我使用了FireBase Google和Facebook认证,注册时获得了当前用户的照片URL。我用过 PINRemoteImage library 要获取图像并将其设置为ImageView,但是在测试时,我得到以下错误。

Domain=NSCocoaErrorDomain Code=264 "The file “photo.jpg” couldn’t be opened because the text encoding of its contents can’t be determined." UserInfo={NSURL= https://lh6.googleusercontent.com/-VImwCn8xJng/AAAAAAAAAAI/AAAAAAAAAAc/Qlp17u7Qxzs/s96-c/photo.jpg }

下面是访问图像的代码:

let userInfo = network.getCurrentUserDate()
        setTextFields(userInfo: userInfo)


func setTextFields(userInfo:UserData){
        do{
            try profileImage.pin_setImage(from: URL(string: String(contentsOf: userInfo.getImageUrl()))!)
        }catch{
            print(error)
        }
    }

在这里 network 是以下类的对象

class Networking{
    func getCurrentUserDate()->UserData{
        let currentUser = Auth.auth().currentUser
        return UserData(username: (currentUser?.displayName)!, email: 
        (currentUser?.email)!, url: (currentUser?.photoURL)!)
    }
}

//Here userinfo is object of following class 

class UserData{
    var userName:String
    var useremail:String
    var imageUrl:URL

    init(username:String,email:String,url:URL) {
        userName = username
        useremail = email
        imageUrl = url
    }

    func getuserName() -> String {
        return userName
    }

    func getEmail() -> String {
        return useremail
    }

    func getImageUrl() -> URL {
        return imageUrl
    }
}

有人能告诉我我的密码有什么问题吗
