When the usesGroupingSeparator is set to yes on iOS18, the groupingSize value becomes 3. groupingSize is different from 0 in earlier iOS18 versions. Is it a bug or will the subsequent official version also make relevant adjustments? We need to adapt the app in advance。 let formatter = NumberFormatter() let temp = NSNumber(floatLiteral: value) formatter.usesGroupingSeparator = true; print(formatter.string(from: temp) ?? "","--",formatter.groupingSize) Print results below: iOS18 2222222 -- 0 earlier iOS18 2,222,222 -- 3

iOS18 beta版本，usesGroupingSeparator设置为yes后，groupingSize值变成了3.与iOS18以下groupingSize值为0不一样。是bug还是后续正式版本也做相关调整？ let formatter = NumberFormatter() let temp = NSNumber(floatLiteral: value) formatter.usesGroupingSeparator = true; print(formatter.string(from: temp) ?? "","分割位数",formatter.groupingSize) //iOS18以下打印结果：2222222 分割位数 0；iOS18打印结果：2,222,222 分割位数 3
