In Turin, Italy, as every year, the "Swift Heroes Conference" took place, and one of our colleagues, Jakub Kiermasz, was invited to deliver a lecture there. During his captivating presentation, Mr. Kiermasz discussed the topic "Building high-performing programs by understanding Swift through ABI". His presentation explained how a thorough understanding of the Application Binary Interface (ABI) in the Swift language can impact efficiency and performance in everyday work. The lecture proved to be a great success, and the room in which it was delivered was packed to capacity.
