Save values from the first launch and I want to keep using that value. How can I do this?

Question

I'm developing an app that gets identification number and age at the first launch. I also want to use these values later on. Where should I save these values in?

Is it automatically saved?

My language is Swift.

Stash it in a file? Hard to answer without much more details... — vonbrand, Aug 13 '15 at 17:16
Your needs seems rather simple so NSUserDefaults is probably good: http://stackoverflow.com/questions/28628225/how-do-you-save-local-storage-data-in-a-swift-application — Stefan, Aug 13 '15 at 17:16

You can save them in NSUserDefaults,

NSUserDefaults *def = [NSUserDefaults standardUserDefaults];
[def setObject:@"value:@"key"];
[def synchronize];

what does synchronize do? – DHK Aug 14 '15 at 07:09
It will write user defaults on disk immediately... but you can ignore some time its slow – Adnan Aftab Aug 14 '15 at 07:37
