what do you mean with 'del'

If you look how to use .filled(), it's shown in video: What information are you missing ?

Could you explain more ? And possibly show screen capture.

Please show code. Is it SwiftUI or UIKit. You have set the 2 tags, which should not be the case.

could you show more code, and show the url (unless it is a local file URL)? Did you try to access the URL directly ? Doc says: This method expects URLString to contain only characters that are allowed in a properly formed URL. All other characters must be properly percent escaped. Any percent-escaped characters are interpreted using UTF-8 encoding. Is it the case ?

Where did you see it is optional ? That's not what doc says here: curatorName string (Required) The display name of the curator. https://developer.apple.com/documentation/applemusicapi/playlists/attributes

Usually it is to call operation B in completion handler of operation A.

Call it in the button handler : var justOnce: Bool = true @IBAction func playStats(_ sender: Any) { //show alert only once if justOnce { let alert = UIAlertController(title: "Stats Important", message: "You can copy and paste the name here when you see the searchbar", preferredStyle: .alert) alert.addAction(UIAlertAction(title: "OK", style: UIAlertAction.Style.default, handler: {_ in justOnce = false gotoSite() } )) self.present(alert, animated: true, completion: nil) } }

I cant see the background in the TabView. There were changes in the display of tab. We refined the appearance of UIToolbar and UITabBar. This updated look removes the background material when scrolled to bottom, giving more visual clarity to your content. In UITabBar, we've enhanced support for SF Symbols, giving great results when using any of your favorite symbols. Look at WWDC21 videos on UIKit for more info. Look here https://developer.apple.com/videos/play/wwdc2021/10059/?time=336 and here for a synthesis of UIKit evolutions: https : / / w w w .wwdcnotes.com/notes/wwdc21/10059/

It is not a constant connection. For instance, when app launches, it connects to Apple and then get notifications. These 2 posts will give some details: https://stackoverflow.com/questions/13897575/apns-apple-push-notification-service-reliability https://stackoverflow.com/questions/25830597/how-to-know-push-notification-delivery-status/25830955#25830955

Does it crash on device or simulator ? You may try the usual tricks: clean build folder restart XCode restart Mac

What happens if you remove 'as? Hello'. I never practiced, so I am more ignorant than you probably. I found this interesting link: h t t p s : / / matthewminer. com/2018/08/25/creating-an-xpc-service-in-swift.html What they do differently is to define connection.exportedInterface in the listener.

the number of source files can make build slower?  for sure, but there is little you can do now (too much work to restructure probably). Do all members of the team experience the same issue ? What is your configuration : Mac model Memory available Here is a discussion where slowlessness occurred with 150 files. May be worth reading even if some old parts are really outdated: https://stackoverflow.com/questions/28032506/how-to-handle-large-swift-project I remember old days when it took 20 minutes to compile the code… We did take care to check the changes before starting compiling. 2 minutes is not that long if you don't try to build after each small change in code.

Please show code, not through a partial screenshot. Screenshot says "Ready to continue". Where did you stop code ? How did you add the image to the project ? I tested in playground, with Test.png in the Resources folder as well import UIKit import PlaygroundSupport let image = UIImage(named: "Test.png")! let uiImageView = UIImageView(image: image) It does work (image is found, not nil). So try to close and reopen the project. Note: by convention, names in Swift do not use underscore, but camelCase: sampleImage

Suddenly my ios 14 for iphone changed to MacOS deployment target. I suspect it changed once it unable to connect to internet. Please explain in detail. Is it in the Xcode project ? Where exactly do you see the change ? If you open the project Targets, what do you see ? Can't you uncheck the Mac checkbox ?
