All good now.

Can you create a JBS issue for this? In order for Skara to deal with this PR, it needs to be linked to an issue in JBS (project JDK, OS iOS).

Let me know if you need help with this.

Can you change the title of this PR into 
8374522: Mobile: Add iOS as a platform in OperatingSystem.java

src/java.base/share/classes/jdk/internal/util/OperatingSystem.java line 106:

> 104:     @ForceInline
> 105:     public static boolean isMacOS() {
> 106:         // Treat iOS as macOS for compatibility with existing libraries unless specific IOS checks exist

I don't think this is needed once the isIOS() call is added? (which is added in this PR)
