I retired a couple of years ago after a flying career in the RAF, followed by a few years working as a defence consultant. As a graduate of the GD Aerosystems Course I was involved in various technical programmes during my time in the RAF and NATO and have (over many years) coded applications in FORTRAN, ALGOL, PASCAL, Aida and C++. I am now interested in developing macOS apps using SwiftUI (but still exploiting Appkit) and recently completed a personal banking app in Xcode. ©
