Answer 1

Max what you can achieve is to get the assembly code.

Getting the Objective-C source code from binary is not possible since there are indefinite number of ways to represent the same assembly.

Answer 2

not like .swf file of adobe flash, the binary file structure of iOS is not open source ... ..., so i think it's so hard even impossible to get the objective-c or swift source code from the binary file ...
