Pass same data from one VC to another VC to another VC

Question

I have a variable named name with string "Magellan" that needs to be added to each VC's nameLabel.

In first VC:

var name = "Magellan"

First VC prepare for segue:

destination?.nameLabel.text = name!
destination?.name = name!

In second VC:

var name = String()

Second VC prepare for segue:

destination?.nameLabel.text = name!
destination?.name = name!

In second VC to go to third VC:

Error: Unexpectedly found nil unwrapping nameLabel.text
Error: Unexpectedly found nil unwrapping name

Error says `nameLabel` & `name` variable are nil in destination VC, which means your Third VC is not initialised with all the properties when this assignment happens. I believe it would fix the problem — Dipen Panchasara, Nov 20 '19 at 06:11
As i said your third VC is not initialised, check why it’s not initialised — Dipen Panchasara, Nov 20 '19 at 15:31
Ah yes, it was flawed because there wasn't a variable that held the name of anything in third VC. I added a variable to third and it worked just fine. thank s\ — magellan, Nov 20 '19 at 15:48

you have to change your

var name = String()

to

var name : String = “”

the difference of this is when you used the var name = String() you are assigning String class to your variable name while for var name : String = “” you are assigning empty value to your string type variable name.
