do
{
let baseDir = try fileMgr.url(for: .applicationSupportDirectory, in: .localDomainMask, appropriateFor: nil, create: true).appendingPathComponent("com.MyCompany.AppName", conformingTo: .directory)
try fileMgr.createDirectory(at: baseDir, withIntermediateDirectories: true, attributes: nil)
}
catch
{
Swift.print("ERROR: can't create baseDir \(baseDir)")
exit(0)
}
