swift - Advise where to store data for iOS app -

i have created app using ionic , cordova , want remake on ios. working ios first time, , cannot figure out how store data. example: have form user has input data, inputs not in 1 view, there must several views. used create empty array , put step step, can't use same view controller on multiple views. tried core data, core data cannot store arrays. object this:

var samplearray = ( duration: 13, dayoftheweek: thursday, personlist: [   (name: rocky,    age: 26),   (name: ralph,    age:23)   ] ) 

the question be: how make input form on several views , should store data, , later able store data core data?

as first comment says, question quite large. when 'one form on several view', consider 'one form per view'. keep simple s... ;) (except if use page control form.)

basically, have 3 ways store data :

• nsuserdefaults : store data in dictionary later use
• file : save data file (why not .csv ?)
• coredata : can persist arrays binary data in core data
