[IOS bug] string.Replace always returns null

See original GitHub issue

Description

string.Replace always returns null when run on IOS, while it returns correctly when running on Android.

Steps to Reproduce

    string test = "1 2 3 4 ";
    string t1 = test.Replace(" ", @",");

t1 should return “1,2,3,4,”, and it does on Android, however t1 is null on IOS.

@danielftz Are you seeing this in the debugger, or is the actual result in code null? If you call System.Diagnostics.Debug.WriteLine(t1);, does it output null or 1,2,3,4, to the console?

We’ve been having some debugger issues in VS, I’m wondering if this is what you’re seeing.

You are correct, Debug.WriteLine() shows the correct output. I was checking the variable value by hovering over it when setting a breakpoint, and the bug shows up.
