ios - Can't encode an array of Strings in Swift -


i can't seem arrays accepted encode function. error getting

"cannot invoke 'encode' argument list of type '([string], forkey: [string])'

var billid: [string]=[] var billnumber: [string]=[] var billtitle: [string]=[] var billdescription: [string]=[] var lastaction: [string]=[] var lastactiondate: [string]=[]  struct statelawdata {     static let state: string="state"     static let lastupdate: string="lastupdate"     static var billids: [string]=[]     static let billnumbers: [string]=[]     static let billdescriptions: [string]=[]     static let billtitles: [string]=[]     static let lastactions: [string]=[]     static let lastactiondate: [string]=[] }  override func encode(with acoder: nscoder) {     acoder.encode(stateabbr, forkey: statelawdata.state)     acoder.encode(lastupdatetime, forkey: statelawdata.lastupdate)     acoder.encode(billid, forkey: statelawdata.billids)     acoder.encode(billnumber, forkey: statelawdata.billnumbers)     acoder.encode(billtitle, forkey: statelawdata.billtitles)     acoder.encode(billdescription, forkey: statelawdata.billdescriptions)     acoder.encode(lastaction, forkey: statelawdata.lastactions)     acoder.encode(lastactiondate, forkey: statelawdata.lastactiondate) }

this within uitableviewcontroller

all keys need strings. in other words, of static statelawdata variables need string, first two.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
