Answer 1

the typealias works the same way as variables. If you want to be global put it outside the class scope at any file.

Answer 2

typealias is use to aliasing the existing Data Types. Its access scope is same as a variable, if its declared in side the block like class, struct, protocol etc then its visibility also remains inside that block only. it can not be used outside to declare a new variables of that type.
