Xcode should include simple themes. Agree??
The themes that bundle with Xcode are all very complex, in the sense that they highlight every token-type a different color, and often use colors that are only slightly different (as there aren't nearly enough distinct colors). Given that these themes are intended to be used, they should be optimized for practicality (not just flexing the power of Xcode). Syntax highlighting is most useful when it distinguishes between things that the programmer distinguishes between conceptually (if I don't know why one variable is blue, while another, apparently similar, variable is red, the highlighting actually makes the code harder to parse correctly). I've also observed a trend towards more minimal highlighting schemes, just generally. I don't have any evidence for this, but assume other people have noticed it too. To offer a concrete example, the following scheme does the usual kinda thing with keywords, comments and literals, but sets everything else to look like plain text, except types, which are gold when they're being declared, and copper otherwise: In my experience, it's notably easier to parse like this, which helps when learning Swift & Co. This is the same theme, applied to a C-family language (Metal): I'm not asking for feedback on the theme specifically. I'm just asking whether you agree that Xcode should bundle a couple of these simpler themes.

Our app rejected by Guideline 4.3 - Design Please Help!
Hello, Our app rejected by following reason: Guideline 4.3 - Design We noticed your app shares a similar binary, metadata, and/or concept as apps previously submitted by a terminated Apple Developer Program account. Submitting similar or repackaged apps is a form of spam that creates clutter and makes it difficult for users to discover new apps. Next Steps Since we do not accept spam apps on the App Store, we encourage you to review your app concept and submit a unique app with distinct content and functionality. Resources Some factors that contribute to a spam rejection may include: Submitting an app with the same source code or assets as other apps already submitted to the App Store Creating and submitting multiple similar apps using a repackaged app template Purchasing an app template with problematic code from a third party Submitting several similar apps across multiple accounts Learn more about our requirements to prevent spam in App Store Review Guideline 4.3. iOS App 1.0App Version Rejection Reasons: 4.3.0 Design: Spam The application is 100% developed by our team and I am 100% sure of it. How can we do it ? Please help.

System fonts file access: allowed for sandboxed apps?
Hello! I am developing an ebook reader iOS app that uses c/c++ codec as a page renderer. The codec uses TrueType as a font rendering engine that requires access to .ttf (or .ttc) files. Currently, I supply TrueType with fonts embedded in the app package, so they lay within the app sandbox. The codec supports the whole unicode plane and many languages that ebooks may use, but the fonts I supply don't have some of the important glyphs (i.e. katakana or hangul). I see that iOS has its own font storage, located in /System/Library/Fonts/ directory. The codec is able to parse this directory and read .ttf files located inside, using these fonts as a fallback in the case when the supplied fonts can't draw certain glyphs. I use opendir and fopen(in "rb" mode) as a way to read the data, and it works well. Does this type of access to the system directory violate the sandbox rule for an app distribution, and, if yes, is there a way to get access to stored .ttf files not violating the mentioned rule?

In Real Time Panoramic View on Apple Vision Pro
I've seen videos on how people on Youtube are using the Apple Vision pro as a Camera Monitor. I found this very neat, but I was wondering if there is a way to make a live stream panoramic view of live CCTV footage, with the Apple Vision Pro. SO my question is, can you make a panoramic view of something that is live, in real time?

4.3.0 Design Spam
Hello, I've a team for developing game in my small company. And we've developed an Obstacle game in Unity from scratch. every single UI, logic & even sound is implemented by our own developers and musicians. It means, every single element is proprietory of our own. I suggest you folks to try out the game in Android playstore by searching the game name as "Cherry Blossom Hills Obstacle" . But once I submitted the same game in iOS App store, the reviewers continously saying, it's a 4.3.0 Design Spam without any to the point feedback basically :( Could you anyone help me resolving this issue? A definitive but even single help/suggestion would be highly appreciated. Regards, Md. Rezoanul Alam.

SectorMark foreground style colors
Dear all, I am using SwiftUI 15.2 and I have created a donut chart using SectorMark. Now, I have three values to show in the chart. When I set up the foregroundstyle, it returns orange, blu and green colors, whereas I'd like to have different colors (e.g. red, yellow and green). Chart(data, id: \.risultato) { dataItem in SectorMark(angle: .value("Type", dataItem.partite), innerRadius: .ratio(0.7), angularInset: 1.5) .foregroundStyle(by: .value("Type", dataItem.risultato)) .annotation(position: .overlay){ Text("\(dataItem.partite)") .font(.caption) } } .frame(height: 150) I'm reporting the final result here below. Do you know how I can customize them? Thanks in advance for your support, Andrea

App rejected because of Guideline 4.3(a) Design
I am building my 2nd React-Native app which is a very simple Notes app. The functionalities are to be able to add, edit & delete notes. And, on the home page where the user can change the orientation of the notes to be in 2 column like a grid or just a list. My app has been getting rejected for Minimal design guideline & I don't know what to do to make it more complex. My first iOS React-Native app was just a single-page Weather app, again that was pretty simple. So, my question is what do I do? OR is the trick that I just keep doing little changes and try to submit & see which one gets accepted??

Accessing passkeys from iMessage Apps
Hi, Does anyone have a good reference list of all capabilities that are unavailable in an iMessage App vs a regular App? In particular, I'm trying to figure out whether I can 1) request a signature via passkey, and 2) send a POST request to an HTTP endpoint. Asking because I haven't been able to find code references or live apps for either. Any pointers would be greatly appreciated! Regards, Lyron

Help Understanding Margins in Custom SF Symbols
Hello! I've been struggling for a while to understand exactly how margins work for custom SF symbols. For example, I'll have two identical svg templates containing near-identical icons (each with a circle outline and a shape in the middle), see attached images. The icons are positioned in the exact same manner in the template, so that the only difference is the symbol inside the circle. When these symbols are exported from SF Symbols and put into Xcode, I noticed that one of the symbols has a slight margin to the right and to the bottom of the symbol, causing it to fall out of alignment with surrounding symbols. I've been trying to eliminate this margin in any way I can think of, but to no avail. Anyone able to offer assistance on how to remove it and/or an explanation as to why it's there?

Performance - App Completeness
Your app or its metadata does not appear to include complete and final content. Specifically, your app description needs to describe in-app features and functionality. App Store users expect the apps they download to be ready for public use. Apps on the store shouldn't include placeholder or incomplete content or information. Next Steps To resolve this issue, please revise your app and metadata so that all of its content is complete and final. For example: Your app binary or metadata should not include "lorem ipsum" text. App metadata should not include placeholder screenshots, such as "screenshot coming soon." Provide an engaging app description that highlights the features and functionality of your app. I received this mail, I made required changes still getting this

Custom SF Symbols for Box Drawing?
I'm trying to find out of SF Symbols is the correct tool for job I have in mind. I'm wanting to create custom box drawing symbols, like those in the unicode block. Box drawing requires the lines from one symbol to connect to the lines of an adjacent symbol. Does SF Symbols allow for this connecting of symbols, or does it create some padding restriction around each symbol, preventing lines from connecting to one another?

Guideline 4.8 Design Login servies
I upload one of my app on app store connect then I get Rejection there it gave me this message that guideline 4.8 design login services. how to solve this issue on app store Can you please guide me about it. This the message i receive from app store: The app uses a third-party login service, but does not appear to offer an equivalent login option with the following features: The login option limits data collection to the user’s name and email address. The login option allows users to keep their email address private as part of setting up their account. The login option does not collect interactions with the app for advertising purposes without consent. Next Steps Revise the app to offer an equivalent login option that meets all of the above requirements. If the app already includes a login option that meets the above requirements, reply to App Review in App Store Connect, identify which login option meets the requirements, and explain why it meets the requirements. Additionally, it would be appropriate to update the screenshots in the app's metadata to accurately reflect the revised app once another login service has been implemented.
