Swift: Cant append Items to Array with two values
Date : March 29 2020, 07:55 AM
it fixes the issue If your goal is to store (Int, Node) tuples in the array, then you should enclose the tuple in parenthesis, either when specifying the array type and when using append: var test: Node = Node()
var arrayTest = [(Int, Node)]()
// ^ ^
arrayTest.append((2, test))
// ^ ^

I wish did fix the issue. Let's say i have a firstArray of PFObject[](from Parse SDK), and it has 7 items, i make a secondArray out of firstArray: , Since you ask for a way to append it, this should work. if firstArray.count > secondArray.count {
for i in secondArray.count..<firstArray.count {
secondArray.append(firstArray[i])
}
}

Append items to [String: Any]() type array Swift

this will help You are not using an array, you are using a Dictionary, which is a collection of key-value pairs. To add a new key and value, you would have to subscript the dictionary and add the new value. So your code should be like this: if userType == "ADMIN" {
param["userType"] = "ADMIN"
} else {
param["userType"] = "USER"
}

I hope this helps . I have the following code (a Parse Server query into a function that gets fired every 20 seconds and checks if there are new rows in the Messages class (table)): if self.theMessages.count < self.messagesArray.count {
let temp = self.theMessages.count
for i in 0..<messDiff {
self.theMessages.append(self.messagesArray[i+temp])
}// ./ For
self.messagesTableView.reloadData()}
