Some SF Symbols (wifi for example) render fine with the variable. But many, mostly ones with the circle being variable, do not seem to work. The SF Symbols app shows them rendering with a variable fine. But in code it doesn't work. Am I missing something or is there a reason? var body: some View { HStack { Image(systemName: "01.circle", variableValue: 0.5) Image(systemName: "figure.wave.circle", variableValue: 0.5) Image(systemName: "wifi", variableValue: 0.5) }.font(.largeTitle) } }

I'm trying to add aliases for columns in a data frame. But the function does not seem to do anything. DF.addAlias("None", forColumn: col.name) print(DF.columnNames(forAlias: "None")) This never prints anything. Any ideas? What am I doing wrong?
