syntax - Swift - assign local variables based on function parameters -

i have initialization pattern immutable class initializer, of parameters passed in @ creation time.
assigning of internal variables based on - there lot of boiler plate , tend forget things , make errors.
curious if there way assign internal properties in function declaration. there key word (like inout)?

for instance now:

private var param1 private var param2 private var param3 ... private var paramn  init(param1, param2, param3, ..., paramn) {   self.param1 = param1   self.param2 = param2   self.param3 = param3   ...   self.paramn = paramn } 

...would cleaner , less error prone, if there way have function param variable internal instance variable:

init(self.param1, self.param2, ...) 

unfortunately, initializer function want generated when no other initializer present, , restricted structs.

i'd recommend filing bug, seems useful feature. keep in mind initializers cannot referenced normal functions (i.e. cannot store them in variables).
