ios - Pass Custom Init Parameter through Storyboard Segue in Swift -


i'm new concept of custom initializers, i'm having hard time understanding if im trying possible.

i'm using source code create messaging app. code written without use of storyboards, i'd implement.

the init implemented in source code this:

init(chat: chat) {     self.chat = chat     super.init(nibname: nil, bundle: nil)     title = chat.user.name }  required init(coder adecoder: nscoder) {     fatalerror("init(coder:) has not been implemented") }

in didselectrowatindexpath method, original code passed custom init parameter way:

 let chat = chats[indexpath.row]     let chatviewcontroller = messagesviewcontroller(chat: chat)     navigationcontroller?.pushviewcontroller(chatviewcontroller, animated: true)

what tried doing creating storyboard uiviewcontroller, setting class original code, is, setting storyboard viewcontroller to: messagesviewcontroller, perform segue. this:

if segue.identifier == "tomessages" {         var messagesviewcontroller: messagesviewcontroller = segue.destinationviewcontroller messagesviewcontroller         let chat = chats[indexpath.row]         messagesviewcontroller.chat = chat     }

then performseguewithidentifier("tomessages", sender: self)

when fatal error: fatal error: init(coder:) has not been implemented:

from research , understanding of original source code, reason because not initializing chat parameter. realize may not on right track, if idea of go here appreciated.

if correct whats going on, specific question how implement parameters in prepareforsegue method, like:

var destinationvc = segue.destinationviewcontroller messagesviewcontroller(chat: chat)

change init code follows

init(chat: chat) {     self.chat = chat     super.init()     title = chat.user.name }  required init(coder adecoder: nscoder) {     super.init(coder: adecoder) }

init(coder:) called whenever uiviewcontroller created via storyboard. in case override called in have written fatalerror() make fail, error getting when executing.

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
