I would like Button to show/ hide button b every time it is pressed. So if pressed it either makes the button appear or disappear picture is attached.
- Connect buttons to code
- You will need to set up both IBAction’s and IBOutlets
- UIButton like many objects have a property that is called “isHidden” which is set to ‘false’ by default and you can set it to ‘true’ through code.
- When you tap button the IBAction func code that corresponding to the respective button will be called with your desired actions
EX:
@IBOutlet weak var button: UIButton!
@IBOutlet weak var buttonB: UIButton!
@IBAction func button( sender: UIButton ) // When button is tapped this code is called
{
buttonB.isHidden = true // Access isHidden Property - Set it to true to hide the button
}
@IBAction func buttonB( sender: UIButton )
{
}
Challenge for you is how to logically hide and unhide the buttonB 
Happy coding
How can I make a if else statement on this. If the button is hidden hitting the button will make it a appear and vice versa. This is what I tried swift is telling my I am missing an if condition.
@IBAction func aa(sender: AnyObject) {
if {b.hidden = true}
else{b.hidden = false}
}
by default isHidden will be true so you access the isHidden property in an if statement to check the condition
if b.isHidden // condition to check if the button is hidden -
{
b.isHidden = false // set the button to be visible
}
your if statement does not have a condition where its checking anything.
