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?

We have developed an iOS app using three fonts: PingFangSC Regular, PingFangSC Medium, and DINAlternate-Bold. Do all three fonts require commercial authorization to be used in the app?

Hello! I am looking to use SF Pro as the main font of my website. This website is used as a place of purchase for some of my products, none of which will actually be using this font. The websites logo will also not be using this font, however I am worried that may be legally unviable. Please let me know if this is an option. I'm not looking to get direct financial gain by using your fonts, just would like to use it for the website. Thank you for your help.

This is a follow-up to my previous question: How to attribute/credit Apple Fonts added to app? In that previous post, I misremembered what I did and said I found fonts via macOS' FontBooks, when instead I came acrossUIFont.familyNames. Since these are included via UIKit, the legal implications should be different. I looked at various license agreements that govern iOS app development but haven't found anything mentioning fonts. Since these are included as part of UIKit, its reasonable to assume that developers are allowed to include these fonts--but in what ways? Am I allowed to let users create, say, documents with these fonts? Am I only allowed to display these fonts? There are 84 fonts, and judging by their FontBook entries, there is a wide range of licenses and restrictions. It seems unnecessarily harsh to have every iOS developer verify each one and figure out which they can legally keep if they want to offer their users access to all (for, say, a text-editing app). There must be some overarching rule that supersedes/encapsulates them, but this rule isn't clear to me after hours of research. I'm not a lawyer, and I don't think Apple expects every app developer to consult their lawyers on whether they can use system fonts. I'm about to send an email to Apple's legal team (I will post their response here if allowed), but in the meantime I want to hear what other devs think about this. In Xcode, entering UIFont.familyNames returns the following: ["Academy Engraved LET", "Al Nile", "American Typewriter", "Apple Color Emoji", "Apple SD Gothic Neo", "Apple Symbols", "Arial", "Arial Hebrew", "Arial Rounded MT Bold", "Avenir", "Avenir Next", "Avenir Next Condensed", "Baskerville", "Bodoni 72", "Bodoni 72 Oldstyle", "Bodoni 72 Smallcaps", "Bodoni Ornaments", "Bradley Hand", "Chalkboard SE", "Chalkduster", "Charter", "Cochin", "Copperplate", "Courier New", "Damascus", "Devanagari Sangam MN", "Didot", "DIN Alternate", "DIN Condensed", "Euphemia UCAS", "Farah", "Futura", "Galvji", "Geeza Pro", "Georgia", "Gill Sans", "Grantha Sangam MN", "Helvetica", "Helvetica Neue", "Hiragino Maru Gothic ProN", "Hiragino Mincho ProN", "Hiragino Sans", "Hoefler Text", "Impact", "Kailasa", "Kefa", "Khmer Sangam MN", "Kohinoor Bangla", "Kohinoor Devanagari", "Kohinoor Gujarati", "Kohinoor Telugu", "Lao Sangam MN", "Malayalam Sangam MN", "Marker Felt", "Menlo", "Mishafi", "Mukta Mahee", "Myanmar Sangam MN", "Noteworthy", "Noto Nastaliq Urdu", "Noto Sans Kannada", "Noto Sans Myanmar", "Noto Sans Oriya", "Optima", "Palatino", "Papyrus", "Party LET", "PingFang HK", "PingFang SC", "PingFang TC", "Rockwell", "Savoye LET", "Sinhala Sangam MN", "Snell Roundhand", "STIX Two Math", "STIX Two Text", "Symbol", "Tamil Sangam MN", "Thonburi", "Times New Roman", "Trebuchet MS", "Verdana", "Zapf Dingbats", "Zapfino"]

I like this font. but in license only allowed for use in Mockup UI. Feel free to use in commercial? https://mobbin.com/apps/bloom-ios-e1251835-34e6-426e-9f94-f9595f2567fa/1c919e9a-d144-4aa0-b788-f9752111e281/screens

What type of licensing does it apply for the usage of FONT_FAMILY='System' in Apple/iOS app?

I've created a font family, but Font Book refuses to include it in the English language set, despite my best efforts. The font has every glyph in the OpenType "Std" set, plus several others. I've checked various boxes for Latin 1 and Macintosh Character Codepages; plus Unicode ranges for Basic Latin, additional Latin, etc, etc. I've compared it to several other fonts that are in the English set, and I can't see anything that they have that my fonts don't. (In fact, many of them seem to have much less!) I've created other fonts that are in the English set, but I've no idea what the difference is. Given that macOS relies on these Language sets, in order to hide the thousands of unnecessary fonts that are permanently installed in the OS, there ought to be some guidance on how to do this.

My visionOS app can install custom fonts. My visionOS app also lists these fonts as available within the application, and I can see them in a list using CTFontManagerCopyAvailableFontFamilyNames I manually track which fonts have been installed. So far, so good. But here’s my problem: When a user uninstalls a font via Settings, I have no way to tell. That’s because CTFontManagerCopyAvailableFontFamilyNames will still list that font because it’s still available within the application. How can I track these changes in my app when a font is uninstalled via Settings?

Helvetica (17.0d1e1) has bugs, hopefully the developers and designers will fix it. Link to the presentation: https://drive.google.com/file/d/16qfpo9Y7Psghv5c_Xl3JBiTPkP4QNaaS/view?usp=sharing

Hi everyone, I’ve been struggling with an issue related to the com.apple.developer.fonts-provided-by-application entitlement in Xcode. Despite configuring everything correctly, I’m still encountering an error stating that the fonts provided by application are missing. Here’s a breakdown of what I’ve done so far: Entitlements File: My entitlements file includes the com.apple.developer.fonts-provided-by-application key set as an array with 28 font items listed (e.g., Lato-Bold.ttf, Montserrat-SemiBold.ttf, etc.). All font names match the actual filenames, including extensions, and are spelled correctly. Info.plist: I’ve listed all the fonts under the UIAppFonts key, and they match the entries in the entitlements file. Font Files in Xcode: All font files are present in my project and included in Build Phases > Copy Bundle Resources. Provisioning Profile: The Fonts capability is enabled in my App Identifier in the Apple Developer Program, and I’ve regenerated my provisioning profile to ensure it reflects this entitlement. What’s Working: Other entitlements in the entitlements file (like keychain access and sandboxing) are functioning correctly, so the entitlements file is linked properly to my app target. The provisioning profile shows everything else is in sync. What’s Not Working: Xcode consistently shows the error "missing fonts provided by application", even though I’ve verified the fonts, file paths, and plist entries multiple times. Questions: Could this issue be related to the placement of the fonts folder within my project structure? Do I need to remove unused fonts or adjust file extensions (like .ttf vs .otf)? Is there another step I might be missing in Xcode or the Apple Developer Program? Any guidance would be greatly appreciated. This has been a challenging problem to resolve, and I’d love to hear from anyone who has encountered something similar.

Hi Support Team, I am new here. I am unable to add my fonts to the asset catalog there is no option to add new font set when I click the plus sign. When I drag my files in they show up as data. I have a Contents.json in the font folder called BeVietnamProFont.font. Is there something I am doing wrong?

Hello everyone, I am having an issue where the attributed text that I have in my UITextView is not scaling dynamically with phone text size, whenever I remove the attributed text logic, it scales fine, however, with it, it stays at a set font size. struct AutoDetectedClickableDataView: UIViewRepresentable { let text: String @Binding var height: CGFloat func makeUIView(context: Context) -> UITextView { let textView = UITextView() textView.dataDetectorTypes = [.phoneNumber, .address, .link] textView.isEditable = false textView.isScrollEnabled = false textView.backgroundColor = .clear textView.font = UIFont.preferredFont(forTextStyle: .body) /*UIFontMetrics(forTextStyle: .body).scaledFont(for: UIFont.systemFont(ofSize: 16.0)) */ textView.adjustsFontForContentSizeCategory = true textView.textContainer.lineBreakMode = .byWordWrapping textView.textContainerInset = .zero textView.textContainer.lineFragmentPadding = 0 textView.translatesAutoresizingMaskIntoConstraints = false textView.setContentCompressionResistancePriority(.defaultLow, for: .horizontal) textView.setContentHuggingPriority(.defaultHigh, for: .horizontal) return textView } func updateUIView(_ uiView: UITextView, context: Context) { let attributed = NSMutableAttributedString(string: text, attributes: [ .font: UIFont.preferredFont(forTextStyle: .body) ]) let detector = try? NSDataDetector(types: NSTextCheckingResult.CheckingType.address.rawValue | NSTextCheckingResult.CheckingType.link.rawValue | NSTextCheckingResult.CheckingType.phoneNumber.rawValue) detector?.enumerateMatches(in: text, options: [], range: NSRange(location: 0, length: text.utf16.count)) { match, _, _ in guard let match = match else { return } attributed.addAttributes([ .foregroundColor: UIColor.systemBlue, .underlineStyle: NSUnderlineStyle.single.rawValue, ], range: match.range) } uiView.attributedText = attributed // uiView.text = text DispatchQueue.main.async { uiView.layoutIfNeeded() let fittingSize = CGSize(width: uiView.bounds.width, height: .greatestFiniteMagnitude) let size = uiView.sizeThatFits(fittingSize) height = size.height } } }

This code: import SwiftUI struct heightProblem: View { var body: some View { Text("\u{1D15E} \u{1D15F} \u{1D160} \u{1D161} \u{1D162} \u{1D163} \u{1D164}") .font(Font.largeTitle.bold()) .frame(height: 50.0) .border(.red) .padding() .border(.green) } } #Preview { heightProblem() } Produces this display: Note the clipping. Lowering the baseline by about 20 brings it into view, but this is a horrible fix for dynamic display (The font is Noto, which works just fine in Xcode, but not in Safari for some reason.)

Hi! I am adding MacOS to a SwiftUI based multiplatform app in XCode, and have noticed an effect on the OTF font I am using. When started for a MacOSX target, the font looks a bit fuzzy, or too bold for the same display: Above is the display running in an iPhone 13 mini simulator, below the macOS version running for the "My Mac" target. The font is in both cases just fetched with static let tkDisplayFont = Font.custom("Segment7Standard", size: 38) Same applies in dark mode: This makes the numbers and especially the decimal point a bit harder to read. The same happens with the system font, but it is not such a problem there: I guess this is handled a bit differently between UIFont and NSFont underneath. Is there a way to tell the font to behave the same way as on iOS?

My app lets users create things with text, and I've included Apple fonts so users can format their text with them. These were fonts I found in the Font Book app that comes with macOS. My assumption is that these, like the San Francisco font, can be distributed with apps. Do I need to attribute these fonts to their creators and publish a license in my "About" page? If so, where do I find the license(s) and what is the proper way of publishing them? Is there anything else I should know? Please let me know if this should've been posted under a different topic and tag

I'm seeing a discrepancy in the metrics of the "New York" system font returned from various Macs. Here's a sample (works well in Playgrounds): import Cocoa let font = NSFont(descriptor: .preferredFontDescriptor(forTextStyle: .body).withDesign(.serif)!, size: NSFont.systemFontSize)! print("\(font.fontName) \(font.pointSize)") print("ascender: \(font.ascender)") let layoutManager = NSLayoutManager() print("lineHeight: \(layoutManager.defaultLineHeight(for: font))") When I run this on multiple Macs, I get two types of different results. Some – most Macs – report this: .NewYork-Regular 13.0 ascender: 12.3779296875 lineHeight: 16.0 However, when I run on my own Mac (and also on the one of a colleague), I get this instead: .NewYork-Regular 13.0 ascender: 14.034145955454255 lineHeight: 19.0 It's clearly the same font in the same point size. Yet the font has different metrics, causing a layout manager to also compute a significantly different line height. So far I've found out that neither CPU generation/architecture nor macOS version seem to play a role. This issue has been reproducible since at least macOS 14. Having just migrated to a new Mac, the issue is still present. This does not affect any other system or commonly installed font. It's only New York (aka the serif design). So I assume this must be something with my setup. Yet I have been unable to find anything that may cause this. Anybody have some ideas? Happy to file a bug report but wanted to check here first.

In this UIKit app, I have to display numbers (from 1 to 100), in a label., on several lines, with 8 numbers on each line. Order is computed by the app for a specific purpose. The numbers are separated by space. Label font is Helvetica Neue 15.0. I want to get them aligned vertically. So, I have a padding so that they are all the same length of 4. Problem: the space have smaller width (half in fact) than digits, so alignment is disrupted: Of course, I can use fixed width fonts (like Menlo), but I've not found one that fits (the zero is barred, which is not looking great in the app). I have tried using class func monospacedDigitSystemFont( ofSize fontSize: CGFloat, weight: UIFont.Weight ) -> UIFont and apply to label.text. To no avail as it modifies only digits, not space char. I have found a workaround, padding with 2 spaces instead of one, but is there another solution ? So I am looking for a space character that would have the same width as a digit. There existe thin space (https://en.wikipedia.org/wiki/Whitespace_character) but not larger space. Does it exist ?

Hello, my app has a custom font for some UI elements. When building with XCODE to my local device, all works and looks great. When distributing with TestFlight, the font doesn't seem to apply! Yes, I've included the .ttf in my Development assets, anyone else having this issue with the TestFlight Distribution of their app?

Hello, I am trying to match the font and the position of the date and time displayed. This is what it looks like: .font: NSFont.systemFont(ofSize: NSFont.systemFontSize, weight: .regular), .foregroundColor: NSColor.labelColor, .baselineOffset: 0.5 It looks great on built-in display, but on external 4K it is incorrect. The baselineOffest is unnecessary, and the font looks skinny in comparison. Can anyone comment on such issue?
