I saved my account through Locksmith Keychain, everything works fine, right now i need to parse the data stored to a textField, how can i do it please?
Here is the code that i use to save my account:
let accountsave = Locksmith.saveData(["account": self.txtAccount.text], forUserAccount: "myUserAccount", inService: "myAccount").
Right now i need to parse the data store to a textfield in swift. Please help
From what I understand of your question you're asking for something similar to this:
let (dictionary, error) = Locksmith.loadDataForUserAccount("myUserAccount", inService: "myAccount")
if let userData = dictionary as? [String:String] {
if let account = userData["account"] {
self.txtAccount.text = account
}
}

I don't know how to get data from Firebase to my UITableView. All tutorials I have been watching used Firebase Authentication, in their videos all worked out fine but while trying to replicate it, I failed.
Here is what I tried:
First there is my Database struct:
And here is my code:
func observePosts(){
let postsRef = Database.database().reference().child("posts")
postsRef.observe(.value, with: { snapshot in
var tempPosts = [Post]()
for child in snapshot.children {
if let childSnapshot = child as? DataSnapshot,
let dict = childSnapshot.value as? [String:Any],
let text = dict["text":""] as? String
{
let post = Post(text: text)
tempPosts.append(post)
}
}
self.posts = tempPosts
self.tableView.reloadData()
})
}
So my question is: How do I get for example the message from a database structure like this?
let text = dict["text":""] as? String {
let post = Post(text: text)
tempPosts.append(post) }
This is wrong. There is nothing like dict["text":""] . First you dont have any data for text keyword , Second you dont write this :""] , you can call as dict["text"].
I think you solution is let text = dict["title"] as? String . But you architecture is wrong. You can declare just one keyword . title 1 , title 2 is wrong. You have to set just title.
If you have followed YouTube tutorials, there's a high chance you did not modify your firebase rules to reflect on non-authenticated users. If you didn't, Firebase ignores every read/write request. To enable this, Edit your firebase rules by:
Set the rules to TRUE
{
"rules": {
".read": true,
".write": true
}
}
However, there's more to it. Don't do it this way unless you're in test mode. Google has some nice docs about it:

Im trying to build a social media app and I have the design down and Ive been up all night trying to figure this out with no luck. I'm fairly new to coding so any help would be appreciated! Thank You! (Also my apologies if this question is already asked. Ive tried looking everywhere and couldn't find anything)
Well to start off you need to create variable which will be database reference and array where the data will be stored such as:
var Array = [String]() //array of strings (usernames)
var ref : DatabaseReference! //define type of variable
then you assign it in viewDidLoad:
ref = Database.database().reference()
using this you'll be able to access your database and load current users:
ref.child("data").observeSingleEvent(of: .value, with: { (snapshot) in
guard let value = snapshot.value as? NSDictionary else {
self.listIsEmpty()
print("The user has no data in the database")
return
}
let userItem = value["Username"] as? [String] //loads the data
self.Array = userItem! //saves data to array
and then finally to write data you start by appending array which we have:
Array.append(textField.text) //reference textfield where username is or variable
ref.child("data").setValue(["Username":self.Array])
I have a dictionary of dictionary of Strings stored in a Firebase database. It can be seen below.
As you can see, each entry is created using .childByAutoId() and contains two variables: text and tag.
I wish to be able to go through all of the entries, and compare the value of text with a variable saved locally in my app. I have tried many ways, but cannot find any solution that works. How should I proceed?
Thank you in advance for your help.
You need to observe database at specific reference and then convert a snapshot that will be send to you. The snapshot represents a fragment of your database at given path
let dbRef = Database.database().reference().child("messages")
dbRef.observeSingleEvent(of: .value) { (snapshot) in
for message in snapshot.children{
let msg = (message as! DataSnapshot).value //message as snapshot
//now you need to cast it to your structure([String:String])
let projectObj = Message(snapshotChild: msg as! [String:String])
//and do your comparison
}
}
How should I access columns that I've added to the User table when I have a currentUser object?
I have a PFUser.currentUser() and I want to access the nickname column that I added via the web interface.
Can I use the currentUser to get the data e.g.:
var nickname = PFUser.currentUser()["nickname"] as String
Or do I have to use a user query? e.g.:
var query = PFUser.query()
query.whereKey("username", equalTo:PFUser.currentUser().username)
var user = query.findObjects().first as PFUser
var nickname = user["nickname"]
If you added date to the column locally, then you have to use the first way as you wrote, or if you added date in the browser, or uploaded to parse.com some way, you have to use the second way.
I would like to give my two cents too. First of all, Daniel was right in saying that if you added the date in the browser or uploaded it to parse.com, you need to use the second way. This is an updated answer with iOS 9 and Xcode 7.2:
var query = PFUser.query()
query!.whereKey("username", equalTo:PFUser.currentUser()!.username!)
do {
user = try query!.findObjects().first as! PFUser
} catch {
print("Error finding user")
}
if user?["rankNumber"] as? Int == nil {
user!["rankNumber"] = 0
user!.saveInBackground()
} else {
print(user!["rankNumber"] as! Int)
}
If I did it any other way, xcode would give me an error saying "failing to unwrap optional". I hope this can help someone!
i am developing a application in which i add contact to contact List. i am able to basic info like name, address, email, phone, notes etc. but i want to add some custom field like userLabel1, userValue1 , bioPersonal, bioWork, bioOther. so i want to add custom fields to address Book'contacts.
whether it is possible to add custom field to contact? if yes , then please suggest any link or sample code?
Basically, there is no way to do that. Address Book doesn't let you add custom fields. However, what you can do is put your data in the "Notes" field for each contact. That will, however, look weird in apps other than yours.
let store = CNContactStore()
// phoneNumberToEdit is the CNContact which you need to update
guard var mutableCont = phoneNumberToEdit?.mutableCopy() as? CNMutableContact else { return }
let phoneNumber = CNPhoneNumber(stringValue: "0123456789")
var currentContact = CNLabeledValue(label: "MyCustomLabel", value: phoneNumber)
mutableCont.phoneNumbers = [currentContact]
let request2 = CNSaveRequest()
request2.update(mutableCont)
do{
try store.execute(request2)
} catch let error{
print(error)
}
