I have an app which uses a RegEx expression to convert text without spaces and make it readable. For Example, it will convert the string IAmOneSentence into I Am One Sentence. The regex expressions is as follows:

var
    Exp: TRegEx;
    value: string;
 
begin
    Exp.Create('(?<=[a-z])(?<x>[A-Z])');
    value := Exp.Replace(TheString, ' ${x}');
    return value;
end;

This code has worked perfectly for me in Delphi Seattle. I run the app in Windows, iOS, and Android.
I upgraded to Delphi Tokyo 10.2 Update 1 and now this code no longer works for iOS/Android.

In iOS/Android I get the following:

Input: GreaterThan Output: GreaterT

If I try my app under Windows I get "Greater Than" which is correct.

Any ideas as to why this stopped working?

Thanks
