UI Text Field postioning Swift - ios

Question

I am a newbie to ios development and am fairly confused about how to position a UI Text field in swift. I am working with sprite kit and am creating a gaem that involves inputing a quadratic equation. I want to position my text fields along side my labels so it say y=_x^2+x+. When I run the following code, my text fields are in the top left corner! What should I do?
override func didMoveToView(view: SKView) {
self.backgroundColor = SKColor.blueColor()
//create y = label
let yLabel = SKLabelNode(fontNamed:"Note-Worthy-Bold")
yLabel.text = "Y = ";
yLabel.fontColor = SKColor.redColor()
yLabel.fontSize = 30;
yLabel.position = CGPoint(x:CGRectGetMidX(self.frame)-300, y:CGRectGetMidY(self.frame)+100);
self.addChild(yLabel)
//create text fielld for coefiecent of x^2 variable
var xSqrCoefInput = UITextField(frame:CGRectMake(10, 10, 30, 10))
xSqrCoefInput.backgroundColor = UIColor.orangeColor()
self.view?.addSubview(xSqrCoefInput)
//create x^2 Label
let xSqrLabel = SKLabelNode(fontNamed:"Note-Worthy-Bold")
xSqrLabel.text = "x^2+";
xSqrLabel.fontColor = SKColor.redColor()
xSqrLabel.fontSize = 30;
xSqrLabel.position = CGPoint(x:CGRectGetMidX(self.frame)-150, y:CGRectGetMidY(self.frame)+100);
self.addChild(xSqrLabel)
//create text fielld for coefiecent of x variable
var xCoefInput = UITextField(frame:CGRectMake(10, 10, 30, 10))
self.view?.addSubview(xCoefInput)
xCoefInput.backgroundColor = UIColor.orangeColor()
//create x label
let xLabel = SKLabelNode(fontNamed:"Note-Worthy-Bold")
xLabel.text = "x+";
xLabel.fontColor = SKColor.redColor()
xLabel.fontSize = 30;
xLabel.position = CGPoint(x:CGRectGetMidX(self.frame)-0, y:CGRectGetMidY(self.frame)+100);
self.addChild(xLabel)
//create text fielld for constant
var constantInput = UITextField(frame:CGRectMake(10, 10, 30, 10))
self.view?.addSubview(constantInput)
constantInput.backgroundColor = UIColor.orangeColor()
}

CGRectMake takes in 4 parameters.
CGRectMake(x position, y position, width, height)
The default starting position is the top-left corner. Your current textfield position is (10,10), so basically you just have to change the x and y positions for all the textfields.
var xSqrCoefInput = UITextField(frame:CGRectMake(10, 10, 30, 10))
If you wish to place the textfield next to the labels, it would be best to get the position of the labels and set the position from there.
