Below is my abbreviated code, which includes every line where I access or set an int value in a hash, before coding it into JSON then sending it out as an HTTP response/data.

The hash item, returnvalue, is an int. My code either returns a 7 or a 15.

When the code below sets returnvalue to 7 (SSSTAGE1), my Swift apps take the http data and decodes it with no problem.

When the code below sets returnvalue to 15 (SSCONVERTING), my Swift apps take the http data and gets a JSON type decoding error.

Further debugging in my Swift app shows that when set to 7 (SSSTAGE1) in the perl code below, the http data received shows:
returnvalue=>7, an int

Yet when returnvalue to 15 (SSCONVERTING), the http data shows:
returnvalue=>"15", a string

I know Perl can treat ints and strings interchangeably. So am curious if anyone has come across this before?

use enum qw(
    SSSUCCESS
    ...
    SSSTAGE1 
    ...
    SSCONVERTING
);

use CGI;
use JSON;
local $SIG{CHLD} = "IGNORE";

my $q = new CGI;
print $q->header();

my %out = (    username    =>"", 
            userid        =>"", 
            status        =>"", 
            filename     =>"", 
            rawfilename    => "", 
            ticket         =>"", 
            returnvalue    => 0, 
            message        =>"");
...

$out{returnvalue}     =     SSCONVERTING;
            
...

if ($ticketinfo{status} == SSSTAGE1){
    $out{returnvalue} = SSSTAGE1;
} 

my $json = encode_json \%out;
print $json;
exit 0;
