There is no file named R.generated.swif in the standard Xcode project. I guess you are using some sort of third party framework. If so, you should better contact to the author of the framework or find a community site for it.

How would I go about it? Copy the item into the right folder where your app can touch it. Your app can modify or delete the copied file as you like.

And I have not verified if the issue is also there when run in a real device. As far as I tried, a file saved in the Documents folder of an app can be opened with a real device. (iPhone 12 Pro Max/iOS 15.0.1)

Can you clarify what you mean by fixed Navigation View? Anyway, you may need to define at least two columns inside NavigationView to test how .columns work. A simple example: struct CollectionView: View { var body: some View { if #available(iOS 15.0, *) { NavigationView { //First column VStack { NavigationLink(destination: //Second column replacement Text("Hello") .navigationBarTitle("Hello") ) { Text("To hello") } } .navigationBarTitle("List", displayMode: .large) //Second column EmptyView() } .navigationViewStyle(.columns) } else { // Fallback on earlier versions } } }

Every Apple's platform have URLSession available. If you just want to explore how to use URLSession, create an iOS App project/Storyboard and add a new method into ViewController. import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. //Call `testURLSession()` here. testURLSession() print("testURLSession() called") } func testURLSession() { //Write code using `URLSession` here... //... } }

When you show your code, please use the code block? What is wrong with 2000-01-01 08:55:00 +0000? What is wrong with 2018-10-14 03:56:23? And what are the expected outputs?

would installing a lower version of Xcode take up just as much space on my hard dive as the current version I already have installed? YES. can I install the lower version on an external hard drive? NO. Xcode needs to be installed on a start up disk. I haven't tried with Apple Silicon Macs, but I do not expect this restriction would have changed. can having multiple Xcode versions installed cause unexpected behavior?  I have installed Xcode 13 as Xcode.app from Mac App Store and Xcode 12.5.1 as Xcode12.5.1.app from More Downloads page. Using both of them for 3 weeks or more, I have not met any severe things yet. How can I make this process in a safe and optimized way?  Just download the other version of Xcode from More Downloads page, expand it there, rename Xcode.app to an appropriate name (before opening it!) and then move it to Applications folder. That's all. Just try.

Is there any official timeline for the deprecation of Rosetta 2 for ARM based Macs? NO, not yet. You should better check the announcements of Apple by yourself. News and Updates But Apple might give us developers only a few months (or less!) till actual removal of some functionalities when announced. (And some sorts of functionalities might be removed silently and abruptly.) You should better prepare now.

You should better read the things robnotyou has written for you and for all the readers.

First of all, you need to get a Mac capable of running Xcode.

I have 42.84 GB of free space available 42.84 GB seems to be too small to install recent Xcode from Mac App Store. I removed many unneeded files and made more than 50 GB to install Xcode 13. If you have some external storage device, download Xcode.xip into the device and try expanding it. More Downloads

It may be caused by many things, but the first thing you should try is defining body: struct SomeView: View { //↓ var body: some View { Text("dummy") } } Update the content of the body later as needed.

I'm following a tutorial and the image literal function auto-populated on the tutorial Image literal is not a thing you type manually. If your tutorial has any parts typing ImageLiteral into a code editor, you should better not rely on the description. Image literals are intended to be automatically generated by Xcode. After you have successfully added an image resource to your project, you can drag the image from the Project navigator to an actual position in the code editor: The detailed behavior may be different in versions of Xcode. Your question is about how to use Xcode and you should better include the version info in your original post. And better use the tag Xcode.

If you really want some help, you should better show more context. Especially in this case, it would be better to show the whole code which can reproduce the issue. (Please show the code as text using Code Block.)

When you show your code, please show it as text using Code Block. With showing easily testable code, more readers would try to solve your issue. And in Swift, only type names start with Capital letter. Score or ScoreButton are not Swifty names. And one more, if TestViewController is actually a subclass of ViewController, it might not be appropriate to instantiate it like TestViewController(). This may cause many critical issues. We need to guess some parts of your code (you are not showing how score of TestViewController is declared), but according to the error message, you may need to write something like this: Score.text = String(newScore.score) When you want to change the content text shown in a UILabel, you need to change the property text, not UILabel itself. And, Swift is a strictly typed language. When newScore.score is Int, you need to convert it to String explicitly. Using String.init(_:) is one way to convert Int to String.
