Welcome to the forum. When you post code, please use the code formatter tool: import SwiftUI struct ContentView: View { var body: some View { VStack(spacing: 20) { Text("SwiftUI Button") .font(.largeTitle) Text("Enabled & Disabled") .font(.title) .foregroundColor(.gray) /* Disabled */ Button("Enabled") {} .buttonStyle(.borderedProminent) .tint(.blue) .controlSize(.large) Button("Disabled") {} .buttonStyle(.borderedProminent) .tint(.blue) .controlSize(.large) .disabled(true) } } } struct ContentView_Previews: PreviewProvider { static var previews: some View { ContentView() } } I tested on iOS simulator, it works

Welcome to the forum. Your question is really too vague. First question: do you want to use AppKit (Cocoa) or SwiftUI ? For SwiftUI, there are many tutorials (including from Apple). For Cocoa, you have to search for: swift developing macapp "cocoa" Here is a very simple one : https://www.youtube.com/watch?v=8zFzldVgG4k Or search for sample code : swift developing macapp "cocoa" sample code Many here: https://github.com/kicsipixel/Cocoa-Samples To search the libraries, the best is to use Xcode documentation directly,

Welcome to the forum. Your code compiles and runs fine (just had to change RoundedCorners by RoundedRectangle and initialise the 3 vars). I also removed the extra closing curly brackets at the end. So where does the error occur ? Probably in a part of code you did not show.

Could you explain ? When does this occur ? What is your question ? Are you working with Xcode Cloud (you should tell). If so, have a look here: https://developer.apple.com/documentation/xcode/source-code-management-setup Or may be here: https://stackoverflow.com/questions/76679770/xcode-cloud-grant-access-to-your-source-code-unknown-error

This is not a question really for this forum which is about helping developers to develop their apps. You'd better post on Apple support : https://discussions.apple.com/welcome But it is known that System uses a significant storage. You may have a look here: https://discussions.apple.com/thread/255463853?sortBy=rank Or here if mobileSync is using a lot of storage: https://apple.stackexchange.com/questions/63207/what-is-mobile-sync-backup-and-why-is-it-taking-so-much-space

Welcome to the forum. Could you show the complete message ? Would your app fit for web app ? Or is it reserved for specific customers ? Read Guideline 4.2 4.2 Minimum Functionality Your app should include features, content, and UI that elevate it beyond a repackaged website. If your app is not particularly useful, unique, or “app-like,” it doesn’t belong on the App Store. If your App doesn’t provide some sort of lasting entertainment value or adequate utility, it may not be accepted. Apps that are simply a song or movie should be submitted to the iTunes Store. Apps that are simply a book or game guide should be submitted to the Apple Books Store.

Is it the full reviewer message ? Guidelines explain what regulated means, with a few examples: as such as banking and financial services, healthcare, gambling, legal cannabis use, and air travel Is your app in one of those categories or something similar ? You could also contact Developers' support.

I am seeking guidance on how to determine the size of the wall so that the portal can fully occupy it. Are you looking on how to compute (in terms of geometry) the sizes of elements ? If so, could you explain what is the issue to calculate the size of the wall. Or to find the size of the wall in an image ? Or on how to implement in code ?

If that may help, I noticed other cases (SwiftUI Mac app) where Xcode 16 generates code that does not work properly when run on MacOS 14 but OK on MacOS 15. And the same code works OK when compiled on Xcode 15. Here is the FB for reference: FB15429756

Where did you download Apple developer app ? Creating an Apple account is free, and you get access to development tools like Xcode. https://developer.apple.com/support/compare-memberships/ Read also DTS support answer here: https://forums.developer.apple.com/forums/thread/742367 So what is it exactly you paid $50 for ? Are you sure it was from Apple ? Or was it a third party app ?

No, it is not possible, as explained by Apple support here: https://forums.developer.apple.com/forums/thread/702447

Welcome to the forum. But this is a forum for developers to get help on their app development, not about product issues. You'd better ask on the support forum: https://discussions.apple.com/welcome

It is a bit tricky with drag and tap. Have a look here to see how you can achieve it: https://stackoverflow.com/questions/64573755/swiftui-scrollview-with-tap-and-drag-gesture

If I understand what you are looking for, you could use accentColor: struct ContentView: View { @State var selectedIndex: Int = 1 var body: some View { TabView(selection: $selectedIndex) { Text("Hello 1") .tag(1) .tabItem { Image(systemName: "house.fill") Text("Home") } Text("Hello 2") .tag(2) .tabItem { Image(systemName: "gearshape") Text("Settings") } } .accentColor(Color.red) } } But now, you should use colorScheme.

Which iOS version do you run ? Must be iOS 16 or over. Then, it is located at the very bottom of privacy and security page. If not OK with iOS 16, have a look here: https://forums.developer.apple.com/forums/thread/716697 This may help as well: https://medium.com/@kshitijsharma94/how-to-enable-developer-mode-on-your-ios-device-and-find-your-udid-b3e46cea58a8#:~:text=Open%20Settings%3A%20Go%20to%20your,Tap%20it.
