Exact, I did not notice option-clean was now disabled. Just use Clean Build Folder. Could you show the 2 class definitions and post a screen copy of the Identity and type Inspector info for the files of the 2 classes ?

Could you show the relevant code ?

Replace         cell.textLabel?.text? = name by         cell.textLabel!.text = name And it works. You can test for safety: if cell.textLabel != nil {         cell.textLabel!.text = name }

You need to track the finger position using func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent) and func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent) Then compute which bar it is and display information accordingly in touchesMoved.

I want to use segue when I click the forget password icon , I do not see any segue in your code, just an IBAction call… One of the frequent reasons for such a crash is that you miss a connection to an IBOutlet from the storyboard, or that this connection is corrupted (if you have changed a name for instance). So, remove all connections from IN to LoginViewController and rebuild them. Do a clean build folder after, in case. Note: you have a typo (missing an n): forgotPasswordEmailCheckCotroller. But that's not the cause of the problem. Why don't you set directly the storyboard ID ForgotPasswordEmailCheckController directly in IB ?

The format for xlsx is pretty complex. That would be probably painful to develop. What you could do is create either a SYLK or a CSV file and open later in Excel. That's much easier to do.

Is it the complete code ? CloseButton is not added to the view, how do you get it on screen ? You should also define its frame. Could you show how you transition to secondView ?

In Swift, generally use nil instead of NULL.

You probably have other properties declared in addition to searchableText, and you don't initialize them…

When you init a CLLocation, you can ask to get speed info at each measure. Then, store this value in an array. And evaluate the max value in the array to get max speed, when you need. What distance do you want to measure: the travelled or the distance from origin ? For travelled distance, each time you get a CLLocation value, compute the distance from previous point (if update is frequent enough, evaluate this as sort(dx*dx + dy+dy) where (dx, dy) is the delta between the two CLLocation. Then increment a totalDistance Float value to compute the travelled distance so far. May read this for implementation details. https://stackoverflow.com/questions/38512443/provide-simple-method-to-get-current-speed-implementing-speedometer

Did you try to use Any as type in struct. Here is a simple illustration (in playground): struct Test { var value: Any } let v1 = Test(value: 1 as Any) let v2 = Test(value: true as Any) let v3 = Test(value: "true" as Any) let tests = [v1, v2, v3] var result : Bool for (i, v) in tests.enumerated() { if let valueInt = v.value as? Int { print("An Int for v\(i+1)") ; result = valueInt == 1 } if let valueBool = v.value as? Bool { print("A Bool for v\(i+1)") ; result = valueBool } if let valueString = v.value as? String { print("A String for v\(i+1)") ; result = valueString == "true" } } Which yields: An Int for v1 A Bool for v2 A String for v3

You should add a tapGesture on the label and implement the action in the tapGesture. Enable user interaction in the label.

Have you a launch screen defined for the app, in a LaunchScreen.storyboard ?

AFAIK, you can go either to the "entry" settings page and navigate from there, or to your app settings. But nowhere else directly. So, you should tell user how to proceed before going to Settings. Settings -> AppleID -> iCloud -> ManageStorage ->

Could you show what you get in the file list ? Should be like this:
