Sorry to say that, we are currently not supporting xamarin. but some customer have implemented that support on their own in the past. Could you please refer the xamarin official doc

How does one specify the permissions for files output by sbt? I need these to be set correctly in order to be able to test the code with my local Apache server.
In the scalaJS project after a clean fastOptJS I
can see that the launcherapp-fastopt.js files are user read only.
$ ls -al target/scala-2.13/
total 240
drwxr-xr-x 6 hjs staff 192 23 Oct 11:08 .

-rw------- 1 hjs staff 48380 23 Oct 11:08 launcherapp-fastopt.js.map
drwxr-xr-x 3 hjs staff 96 23 Oct 11:08 update
Apache won't see it with those permissions so I have to change the mode on the files like this:
$ chmod -R a+rX target/
$ ls -al target/scala-2.13/
total 240
drwxr-xr-x 6 hjs staff 192 23 Oct 11:08 .

Is there a way to specify the rights in sbt for the produced artefacts so I don't have to chmod everytime I compile?
For a use case see the Launcher App

I am not sure, but probably you should append not only the directory names, but also the full path. Get the application directory, and append to it the sub-directory names.
QString appFilePath = QCoreApplication::applicationFilePath();
QStringList paths = QCoreApplication::libraryPaths();
paths.append(QString("%1/%2").arg(appFilePath).arg("libs"));
paths.append(QString("%1/%2").arg(appFilePath).arg("platform"));

The sort must skip past the date portion of each line, then sort numerically (eg, starting with the 12 or 13), using '.' as a field separator.
I thought of two approaches, but am having difficulty with the sort -k syntax, if it's supported at all:
(1) Skip the first 36 characters, then with '.' as field separator, sort numerically on the next 4 fields.
(2) With field separator as whitespace, skip to the 7th field, then change the field separator to '.' and sort numerically on the next 4 fields.
The alternate is a little Perl script, but can't Unix sort do this "simple" task?
Here's a command line which uses awk to put the version numbers first, sorts using four numerical keys, then uses cut to get rid of the temporary at front:
$ ls -loghF | awk '{ print $7, $0; }' | sort -n -t. -k1,1 -k2,2 -k3,3 -k4,4 | cut -d' ' -f2-

The sort command there is borrowed from this answer. Another answer suggests sort -V (version sort), but my version of sort doesn't have it (yours might, though, so it's worth trying). Version sort is likely to be specific to newer GNU coreutils (my Linux box has it, and sort is from GNU Coreutils 8.5).
With version sort:
$ ls -loghF | sort -k7,7V

This isn't the fastest way to do it, but it is fairly simple to explain:
ls -loghF |
awk '{ print $7 " " $0 }' |
sort -t. -k 1,1n -k 2,2n -k3,3n -k 4,4n |
sed 's/^[^ ]* //'
The 'awk' command copies the directory field to the front of the line; the sort command only uses a single delimiter (.; I don't think you can use different delimiters for different parts of a line) and then sorts the 4 numeric parts explicitly in numeric order. Then the sed removes the field that was added at the front.
This is a simple version of 'make it easy for sort to find the keys', because splitting the input is one of the expensive operations in sort.
FYI: Here's what I ended up doing.
Special thanks to: http://www.sysarch.com/Perl/sort_paper.html
$ ls -loghF | perl -e '
use strict;
my #in = <>;
my #out = grep(m|\d+\.\d+\.\d+\.\d+/$|, #in);
print sort {
my #aa = $a =~
m|(\d+)\.(\d+)\.(\d+)\.(\d+)/$|;
my #bb = $b =~
m|(\d+)\.(\d+)\.(\d+)\.(\d+)/$|;
$aa[0] <=> $bb[0] or
$aa[1] <=> $bb[1] or
$aa[2] <=> $bb[2] or
