Hi there. A question got me thinking when I was studying GMAT exam with a iOS App. How they write many advanced mathematical symbols in iOS App with swift programming? They look really neat and organized, and these mathematical symbols are texts, but not pictures. Some choice has “box”, which allows you to enter equation or numbers. If anyone knows how, please let me know. Thank you so much!!
One way is through Xcode. Xcode has Emoji and Symbol characters that you can use. To access it go to Edit → Emoji & Symbols. There you will find a collection of characters and symbols that you can use in your application.
