@classdoesn’t import the file, it just says to the compiler “This class exists even though you don’t know about it, don’t warn me if I use it”.#importactually imports the file so you can use all the methods and instance variables.@classis used to save time compiling (importing the whole file makes the compile take more time). You can use#importif you want, it will just take longer for your project to build.
