There is only one very simple difference between a variable and a constant, and the name already says it. A variable is variable, what means that you can change it's content later in you code, with a constant you cant. For example if you set a var named var1 with the string: "i am a var" and later on you set var1 = "i still am a var" and than print var1 you will get "i still am a var". With a constant (let) when you try to change it's content Xcode will start complaining because something that's constant can't change. I hope that it's clear now.
