Do you create views in Interface Builder ? If so, the view on top must be after in the list of views (as for Red View On Top, after Green View Below in list): You get:

My reading of the guidelines is that for medical app, the source must be approved by an official source, such as Ministry of health, W.H.O, …

Declare that the class conforms to UITextFieldDelegate Use the func:      func textFieldDidChangeSelection(_ textField: UITextField) { } to test there are not 2 decimal points (and maybe test that you only have digits ?) Code should be like this (I assume there is only one textField in your view, otherwise you have to test that textField is the correct one): func textFieldDidChangeSelection(_ textField: UITextField) { if let typedText = textField.text { // What have we typed in ? var dotCount = 0 for c in typedText { // count dot or comma if String(c) == "." || String(c) == "," {  dotCount += 1  } } if dotCount >= 2 { // remove last typed                     textField.text = String(typedText.dropLast()) } } }

You should show how you handle the passFavNotification (I mean, where do you call handleFavNotification)

Have you tried to reboot it ?

@Roy_Good from what  shaikhalid posted, seems he/she has tried most of what is described here. Did you too? https://support.apple.com/en-us/HT201412

Could you explain better what you get and what you want ? I try to formulate You click button, calling obrirAmbCodi, which opens a window finestra3 when you click again on that button, a new, similar window opens (probably stacked over previous one ?) in such a case, you would want just to display the already opened window, not create a new one. Is that correct ? If so, you could: In the class where obrirAmbCodi is, declare a var var controller: NSWindowController? test if nil ; if so instantiate     @IBAction func obrirAmbCodi(_ sender: NSButton) { if controller == nil {         let storyboard:NSStoryboard = NSStoryboard(name: "Main", bundle: nil) controller = storyboard.instantiateController(withIdentifier: "finestra3") as? NSWindowController // could be nil             controller?.showWindow(self) }     } dismiss the controller when you close window and set to nil Note: you could test if the window is open instead of testing controller

The thing is I need noRepFav because I don't want duplicates in my array. There are very simple ways to achieve this with a single array. Before appending to this array, check if the item already exist. I'm confused with this code: you have at least 2 different TableViewControllers (FavouritesVC, HockeyDetailVC). Both of them have handleFavNotification. It is not clear where you delete, where you add, where it is added back.

You cannot do that. info.plist is part of bundle and cannot be changed at runtime. See details here for instance: https://stackoverflow.com/questions/40214673/setting-value-to-info-plist-file-from-swift?noredirect=1&lq=1 But why change the info.plist and not directly the appearance ? https://developer.apple.com/documentation/appkit/nsappearancecustomization/choosing_a_specific_appearance_for_your_macos_app

I probably miss something obvious. But why don't you increment counter in the for idx loop ?

Because you have an error in your code ! Which crashes in thread 8. How do you want we guess where it could come from if you do not show the code where it occurs ?

AFAIK, answer is no. A few reference material: https://stackoverflow.com/questions/36439912/live-updates-with-cmpedometer-coremotion h t t p s : / / medium.com/simform-engineering/count-steps-with-cmpedometer-on-iwatch-94b61bc3b87e The pedometer is a higher level object on Core motion. It sets its own refresh rates and we can get updates through a closure, so it’s on its own schedule, not one we can control. Just an idea, for what it's worth. Using the actual speed and the recent ratio steps/speed, maybe you could estimate the count at the frequency you want, and display it. Then, as soon as you receive a new pedometer information, update everything. I don't know if that would be good enough or too chaotic information display.

Do you use the same font "PingFangSC-Regular" in both cases ? NSStringDrawingUsesFontLeading doc says Uses the font leading for calculating line heights. I don't know if this value or this computation has changed in iOS 15. I would advise to file a bug report.

No, never met this problem. Could you tell: Which version of Xcode ? On simulator or device ? Which OS version in anycase. Have you changed the button programmatically, in anyway ? Are you sure you have nothing overplayed over "Back" ? Could debug view hierarchy when running to check for this ? Eventually, create the smallest possible project to reproduce and attach the full project folder here.

Thanks. The explanation in doc is not very clear. But seems coherent with my understanding. And the Xcode doc for UNCalendarNotificationTrigger confirms Overview Create a UNCalendarNotificationTrigger object when you want to schedule the delivery of a local notification at the specified date and time. You specify the temporal information using an NSDateComponents object, which lets you specify only the time values that matter to you. The system uses the provided information to determine the next date and time that matches the specified information. Listing 1 creates a trigger that delivers its notification every morning at 8:30. The repeating behavior is achieved by specifying true for the repeats parameter when creating the trigger. Listing 1 Creating a trigger that repeats at a specific time var date = DateComponents() date.hour = 8 date.minute = 30 let trigger = UNCalendarNotificationTrigger(dateMatching: date, repeats: true)   I don't know how to do directly what you want. A workaround would be to create multiple notifications, as described here: https://stackoverflow.com/questions/50027190/uncalendarnotificationtrigger-every-3rd-day
