Summary: At WWDC24, a new transition was introduced by the Apple Design team (.contentTransition(.symbolEffect(.replace))) I was writing a post about it on my LinkedIn (https://www.linkedin.com/in/alex-fila/), and out of curiosity I tried multiple symbols with slashes. Many of them were not well center aligned during a new symbol effect. Some of the examples are: "speaker.fill" : "speaker.slash.fill”, "eye.fill" : "eye.slash.fill”. Please check the attached Swift file for more details and full SwiftUI View with issues. Steps to Reproduce: Create a new IOS App project in XCode. Create a new SwiftUI File. Initiate state variable: @State private var isSpeakerOn = true. Create a new image with transition: Image(systemName: isSpeakerOn ? "speaker.fill" : "speaker.slash.fill") .contentTransition(.symbolEffect(.replace)). 5. Create a switcher or set a timer with a constant variable to toggle isSpeakerOn value (see attachment file). 6. Toggle isSpeakerOn value. 7. Observe the issue (2 symbols are not well center aligned during transition). Expected Results: During transition .contentTransition(.symbolEffect(.replace)) 2 SF symbols ("speaker.fill" : "speaker.slash.fill”) are well center aligned. Actual Results: During transition (when slash slowly appears on top of SF symbol), the main symbol is moved a few points up, creating a decentralized effect and making the user experience feel inconsistent. Notes: There are 200 SF Symbols with .slash that might be affected. It happens on latest Xcode and macOS versions, and could be a top priority for the Apple Design Team. import SwiftUI struct BUG: View { @State private var isSpeakerOn = true let timer = Timer.publish(every: 1.5, on: .main, in: .common).autoconnect() let columns = [ GridItem(.flexible(), spacing: 20), GridItem(.flexible(), spacing: 20) ] var body: some View { LazyVGrid(columns: columns, spacing: 60) { Text("❌").font(.system(size: 100)) Image(systemName: isSpeakerOn ? "speaker.fill" : "speaker.slash.fill") .font(.system(size: 200)) .frame(width: 200, height: 100, alignment: .center) .contentTransition(.symbolEffect(.replace)) .symbolRenderingMode(.palette) .foregroundStyle( Color.primary, Color.accentColor) .onReceive(timer) { _ in withAnimation(.spring(response: 0.3, dampingFraction: 0.7)) {isSpeakerOn.toggle()}} Text("✅").font(.system(size: 100)) Image(systemName: isSpeakerOn ? "bell.fill" : "bell.slash.fill") .font(.system(size: 170)) .frame(width: 150, height: 150, alignment: .center) .contentTransition(.symbolEffect(.replace)) .symbolRenderingMode(.palette) .foregroundStyle( Color.primary, Color.accentColor) .onReceive(timer) { _ in withAnimation(.spring(response: 0.3, dampingFraction: 0.7)) {isSpeakerOn.toggle()}} Text("❌").font(.system(size: 100)) Image(systemName: isSpeakerOn ? "eye.fill" : "eye.slash.fill") .font(.system(size: 150)) .frame(width: 200, height: 100, alignment: .center) .contentTransition(.symbolEffect(.replace)) .symbolRenderingMode(.palette) .foregroundStyle( Color.primary, Color.accentColor) .onReceive(timer) { _ in withAnimation(.spring(response: 0.3, dampingFraction: 0.7)) {isSpeakerOn.toggle()}} } .padding(40) }} #Preview { BUG() }

Hello, I have the following code: struct SettingsButton: View { var action: () -> Void @State private var rotate: Bool = false var body: some View { Button(action: { rotate.toggle() action() }, label: { Image(systemName: "gearshape") }) .symbolEffect(.rotate, value: rotate) } } For some reason, my button is not rotating. Other effects such as pulse and bounce work as expected. I applied the .clockwise direction thinking it needed a direction set, but that didn't work either. I also tried using the symbolEffect with isActive, and that didn't work. Lastly, I thought there may be an issue with Xcode so I closed that and reopened, but still not working. Any ideas?

I've been losing countless hours of work trying to create a variable-width SF Symbol that supports interpolation, no dice. Both Sketch and Figma output SVGs that are not interpolatable. After numerous hours of research, I believe it's due to the fact that when outlining strokes, these editing tools introduce artifacts into the shapes —​ sometimes I get very short line segments where there would not be needed, sometimes a 3-point curve gets expanded to a 4-point curve, but not in all weights. It's always inconsistent. So my only question is rather simple: what's the graphic editing tool Apple uses to create hundreds of symbols? Clearly you cannot edit the stroke of ALL curves by hand, it's inhumane. Sketch? Figma? Illustrator? Inkscape? Affinity? I'd like a definitive answer from someone internal so that I can at least try to use the same tool as you without wasting more hours.

Hi, I've been trying for an hour to turn the symbols in sf symbols from left to right to right to left, I'd appreciate some help

I'm getting a weird response from Xcode in trying to use symbolVariant(.contains). I also don't understand why it demands the type cast. What am I doing wrong? Here's the code as text: import SwiftUI let Variants: [SymbolVariants] = [ .circle, .square, .fill, .rectangle, .slash, .none ] func varAvail(_ image: Image) -> [SymbolVariants] { var res: [SymbolVariants] = [] for variant in Variants { if image.symbolVariant(.contains(variant)) as! Bool { res.append(variant) } } }

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

I'm trying to create custom SF symbols and am getting this error message when I validate the template. It doesn't matter if I Export Template or Symbol. Also, it doesn't even matter if I make any changes or not, as long as it is opened in Adobe Illustrator or Inkscape and then I save it, I will get this error message when validating.

Hello everyone, I've been having a bit of trouble with the .symbolRenderingMode(_:) modifier. When trying to apply it to a single button in a toolbar, it does not work at all. The symbol is always rendered as monochrome. However, I've realised that with this little hack I can achieve the expected results, but this is not ideal. .toolbar { HStack { Button("", action: {}) // The hack Button("Button", systemImage: "line.3.horizontal.decrease.circle.fill", action: {}) .symbolRenderingMode(.hierarchical) .foregroundStyle(.blue) } } I've submitted a bug report (FB16129223) but in the meantime, is this my only solution ? Side note: the foregroundStyle(_:) modifier is ignored as well.
