Reply to Compiler stuck::considering giving up on SwiftUI

It's going to be a big challenge to port an existing project to SwiftUI. What you describe makes a lot of sense. Most people never encounter this error anymore because they are starting small, with a new project. That being said, you specifically said that you were porting a project over to iPhone. I don't think trying to do that kind of massive port from a foreign architecture is going to be any more pleasant in UIKit. I recommend starting small, with a new project. Build the bones of your UI to match the old project. But don't attempt to port the entire thing at once. Follow the path of least resistance and write the code the way SwiftUI or UIKit expects.

iCloud file reading and writing (iOS)

On my first attempt at adding iCloud to my existing app this is how far I've gotten. For reasons that I won't go into, the use case for my app does not need coordination. I have successfully made my app write a file to the Documents directory of iCloud and read back that same file without errors. In testing on a real iPhone 13 and iPhone 7 I have verified that my app can write a file to iCloud from the iPhone 7 and then read back that same file on the iPhone 13, so I know that the file truly exists in the cloud. But when I make my app on the iPhone 13 write to iCloud, my app on the iPhone 7 says the file does not exist. Exactly the same build of my app is running in both phones. This is problem #1. Problem #2 is that none of these files appear in the iCloud section of the Files app on either of these Phones, nor do they appear in the iCloud section of my Mac. All devices are signed in to my same Apple account in iCloud. Also my info.plist file in the app contains: NSUbiquitousContainers iCloud.com.{my domai

Denmark's biggest mobile payment service is skirting IAP rules

Hello I recently discovered that Denmark's (and soon the rest of the Nordic countries) biggest mobile payment service - MobilePay - is seemingly getting away with selling digital products in their app without using IAP. I am confused how this is possible, as I spent a lot of time making sure I understand the rules -- and I'm quite confident I do, so the only conclusion I can reach from this is that this is a violation that has not been discovered. If it isn't, I would like an explanation. So, what am I talking about? First; MobilePay is an app that lets you send money to whoever, essentially a Danish version of CashApp. You attach a credit card, and you can transfer funds using people's phone numbers. Nothing about this is problematic. There are some fees involved, which is also fine. But. You can select to wrap your money in digital wrapping paper, which can be unwrapped by the recipient to reveal the amount you transferred. This is, no matter how you spin it, a digital product. It adds about 1 USD to the tr

Reply to Scrollview and a background image set to scaledToFill....

I think you're looking for something like this: import SwiftUI struct ContentView: View { var body: some View { ScrollView { VStack(spacing: 24) { ForEach(1..<20) { i in Text(Line (i)) } } } .frame(maxWidth: .infinity, maxHeight: .infinity) .background( Image(background) .resizable() .scaledToFill() .ignoresSafeArea() ) } } #Preview { ContentView() } The main difference is that my code adds a background to the ScrollView rather than putting everything on top of an image via a ZStack. When you do it your way, you've kind of told everything on top of that layer how big they'll be, which is why your ScrollView is distorted, and bits of it disappear off the screen.

Reply to System Data full after clearing safari, messages, offloading apps/reinstalling apps

These are the Developer Forums, where developers of apps for Apple's platforms ask each other for hints and tips on coding. Your question is more of a product support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks. System data is the System, i.e. iOS plus necessary files such as logs and cache files. That number will stay pretty static. There's not really a lot you can do to reduce that. Try and offload some of your data to iCloud. Enable iCloud Photos and turn on Optimise iPhone Storage in Settings > Apps > Photos. Regardless, you have a 64GB iPhone, which isn't that big these days. It might've been fine five years ago, but not really now.

Reply to Issue: Review Team Unable to Access Website (WebView App)

Lots of people write apps that connect to their web servers. I think it's pretty unusual when an app doesn't do that. Internally, Apple is really old-school, big-iron corporate. I don't know specific details of specific products, but Apple's a big company, so there are lots of them. Generally speaking, if a 3rd party corporate networking/security app was a Big Deal 15 years ago, Apple probably still uses it today. Probably the two most important things to check are IPv6 and SSL. Make sure your app works in a purely IPv6 environment. Curiously, this policy is 9 years old now. Apple has a solid track record of announcing major changes 9 years before making a hard change. People who ignore those warnings because their app is working fine then get blindsided years later. Also, Apple can be very strict about SSL certificates for its own use. It really doesn't matter if your website works great in Chrome. It might not work from an Apple app or from an Apple internal network. People who ro

Reply to why can a dylib missing dependency still be loaded?

I’m not sure what’s happen in your exact case but I wanna step back and ask about the big picture. /usr/lib/libc++.1.dylib is macOS’s built-in copy of the C++ standard library. It’s meant to be referenced by an absolute path: % grep install-name /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/lib/libc++.1.tbd install-name: '/usr/lib/libc++.1.dylib' Why are you trying to load it via an rpath-relative reference?

Xcode unable to find a destination matching the provided destination specifier?

I am using react-native to build an ios app. After updating to macOS Big Sur - Version 11.6 a couple of days ago, my build started failing when using VS Code. I am getting this error- xcodebuild: error: Unable to find a destination matching the provided destination specifier: { id:5F135958-0789-4409-9C64-6D3939A54B03 } Available destinations for the MediLab scheme: { platform:macOS, arch:arm64, variant:Designed for [iPad,iPhone], id:7C6CDA97-38E3-591E-A991-8C4580349A5C } { platform:iOS Simulator, id:24E5BDF6-3EE5-4232-9E39-EBF4B48A9A2E, OS:15.0, name:iPad (9th generation) } { platform:iOS Simulator, id:FF4BFEEB-3DA8-4BB3-93E6-E3889C94F556, OS:15.0, name:iPad Air (4th generation) } { platform:iOS Simulator, id:624A99D1-6A8E-440A-AB96-3F7C0828C701, OS:15.0, name:iPad Pro (9.7-inch) } { platform:iOS Simulator, id:9C8A5850-F1D0-4B81-B7BE-2242BC3A1DB3, OS:15.0, name:iPad Pro (11-inch) (3rd generation) } { platform:iOS Simulator, id:2B47305A-7F97-44AE-8E53-30456CF02FBC, OS:15.0, name:iPad Pro (12.

Reply to iPad/iPhone - Display best practices….

All my apps work on both the iPhone and iPad, but due to the amount of changes - some structural - that are required to get an iPhone version to look and work properly on the iPad, I use two different views: @main struct MainApp: App { // ... var body: some Scene { WindowGroup { if(UIDevice.current.userInterfaceIdiom == .pad) { TabletView() } else { PhoneView() } } } } So, if the user is using an iPhone, the PhoneView() is the main entry point. For iPads, it's TabletView(). The reason I did this is because the iPad has much more space and allows me to do more things, so the TabletView has more things in it. Also, I'd rather not have one big, unmanageable View full of if ... else statements and ternary operators. It also means your spacers and padding values apply only to that device type. Where the two views have similar UI, those bits are extracted into their own little View structs and called within those two main entry points. When you separate out the two views you may find you're duplicating som

Reply to iOS18, certificates, mail app and domain

I’ve asked as well on the app support forum. As a dev, I often answer questions on my github that are config or usage related. And yes, these are my apps so it’s different but these questions are normally asked on dedicated support forums not on GH. Anyway, I’m not sure we need to make a big fuzz about that, let’s say then that my ask to devs in general here, related to my issue, is ”please don’t do the same in your apps and make sure that when you use certs, you don’t forbid use of IP-addresses directly”.

Cannot access current path from NavigationPath — need breadcrumb trail like Files app

I’m building an app similar to the Files app, where users navigate through folders using a NavigationStack with a bound NavigationPath. I need to display the current path — meaning a breadcrumb-like UI that shows the folder hierarchy the user has drilled down into. However, I’m running into a big limitation: We can’t access the current values inside NavigationPath. It doesn’t conform to Sequence, and there’s no documented way to extract the typed path elements to construct a path string like Documents / MyFolder / Subfolder. To work around this, I tried maintaining a separate [FileItem] array alongside NavigationPath, and that works well in iOS 17+ and iOS 18. But when I test on iOS 16, and navigate to another detail view in my NavigationSplitView, the app crashes. I searched around and found others hit this issue too — switching back to NavigationPath fixes the crash, but now I’m back to square one: I can’t figure out the current folder path from the stack. So my questions are: • Is there any suppor

Reply to BGAppRefreshTask expires after few seconds (2-5 seconds).

Regarding using notification to test the behavior, the idea is nice, but the slight problem is that it requires somebody closely watching the phone to quickly react to unpredictable background fetch event. Not really. The sysdiagnose capture covers a very long period of time (hour to days, depending on circumstances) so as long as the device hasn't been rebooted* it doesn't actually matter when you collect the log. While closer in time is theoretically better, for an issue like this there isn't really any practical difference between collecting a long immediately vs 30+ minutes later. *A lot of log data is purged at reboot, so that is a problem for this sort of thing. For most issue I actually recommend developer wait 5-10 min. after an issue before they trigger the log, as that makes sure that the log noise of the sysdiagnose isn't mixed in with any trailing log data. I'll also say that the upper time band here is pretty big. I don't like saying sure, collect it 4 days later because things do go wro

Reply to Directive 4.8 - Conception - Services de connexion

Bienvenue sur le forum. Est ce que votre app utilise 'un service de connexion tiers,' tel que Facebook Login, Google Sign-In, Sign in with Twitter, Sign In with LinkedIn, Login with Amazon, ou WeChat Login Si non, il faut le signaler au reviewer, que vous n'êtes pas dans ce cas. Si oui, vous pouvez soit utiliser la connexion avec Apple login, à la place de celle utilisée, soit montrer que vous respectez les exigences 2 et 3. Attention, la traduction que vous avez des guidelines est imprecise. Les exigences sont: le service de connexion limite la collecte de données au nom et à l'adresse électronique de l'utilisateur ; le service de connexion permet aux utilisateurs de ne pas divulguer leur adresse électronique lors de la création de leur compte ; et le service de connexion ne collecte pas les interactions avec votre application à des fins publicitaires sans le consentement de l'utilisateur. Et enfin, mettez à jour les copies d'écran si besoin.
