I'm running iOS17 App and getting this message in the Xcode 15 console. Five times every time I goto one of the pages in my NavigationStack. Google's search engine has never heard of this. "Requesting visual style in an implementation that has disabled it, returning nil. Behavior of caller is undefined." Anyone got a clue of what I've disabled - without being aware of it. And what code is going to pick up a butcher knife and stab me at 3:47am - very undefined behavior! Is it just me or is this message missing some important detail? Thanks David.

This appears to be a common issue with little to zero known resolutions over the years.... Appears to happen with previous versions of Xcode. Does Apple or the community have a fix? I've checked out the sources in a new location from my github - Same/similar issue. I've started a completely new project from scratch and then dragged my source into it... same/similar issue. I've killed the swift-frontend process & closed reopened Xcode. I've cleaned the build folder / delete DerivedData & restarted the computer... same/similar issue. Any ideas?

I'm looking for a way to easily (or more easy than rewriting a time series data framework) deal with stock market data. I apparently need to preprocess much of the data I could get from typical APIs (Finnhub.io, AlphaVantage.co) to remove the weekend days from the datasets. Problem: When using the awesome NEW Charts framework to plot prices by daily close price - I get weekends and holidays in my charts. No "real" stock charting tool does this. They some how remove the non-market days from their charts. How? Researching I found the Python Pandas library for TimeSeries data... Can Apple's TabularData do this TimeSeries data manipulation for me? Can to share an example? Thanks! David

I'm wondering if Apple will add a weekDay type ScaleType for plotting stock market charts. The Date scaleType assumes that the weekend days (Saturday/Sunday) should be within the plotted data. But the typical stock market chart omits the weekends and holidays (non-market days) from the charts. Would Apple be interested in providing this new Chart Scaling Type. Or is there a way to extend the Charts Framework to allow this type of chart? For Example: the X Axis might look like: M T W T F M T W T F T W T F

Inside an iOS Menu the icons display to the far right of the Text. Which is different than a Label outside of a Menu(). I'm wondering why - and why I cannot change that with a custom LabelStyle? struct IconFirstLabelStyle: LabelStyle {     func makeBody(configuration: Configuration) -> some View {         HStack {             configuration.icon             configuration.title         }     } } That custom style does not work in iOS15. Is there another way to create the effect in the Menu that is displayed in the Human Interface Guidelines: https://developer.apple.com/design/human-interface-guidelines/ios/icons-and-images/system-icons/ Icons on the left - text follows.

I see a Code section on Developer app - but it has just a few snippets of code - not the assets that he drug into the project. Where are the assets & starter code? hmm... can not attach a image of the Code section of Developer.
