I was trying to compile an app that contains custom SF Symbols with Template 6.0 in Xcode (using Version 16.2 (16C5032a) on my Macbook running Sonoma 14.7.3 (23H417)). However, when building, I got the error The SVG file provided for the symbol image set ’(SVG file name)‘ is not suitable: Template format 6.0 is newer than the version that this software supports (5.0) for the custom symbols' SVGs. Attempting to preview the symbols in Xcode also seems to crash and force Xcode to quit. I am assuming this is something to do with the symbols not being compatible with my Xcode version, but the problem is that it should work since I am using Xcode 16.2, the latest stable version currently. The SVGs themselves even mention "Requires Xcode 16 or greater", which means they should work. Unfortunately, I could not find anything about this online (except another old post from 2023 with no answers), so I'm at a loss. The only possible cause that I can think of is because I'm running Sonoma instead of Sequoia (I'm using an ancient Intel Macbook which doesn't support Sequoia), but the official SF Symbols website says that it requires Ventura or later.

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 ?

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?
