Here are some quick little code tips for creating a settings bundle in Swift for iOS. Settings are very easy to setup for iOS. Just note that the simulator currently does not work with settings correctly. The code in this post does work just fine on a device. Load the Defaults into the Settings: let appDefaults = [SettingsKeys.namePreferenceKey: “Default Name”] NSUserDefaults.standardUserDefaults().registerDefaults(appDefaults) Get the Settings value: var namePreference = NSUserDefaults.standardUserDefaults().stringForKey(SettingsKeys.namePreferenceKey) Save…

NSDate and NSCalendar is a bit different in Swift. Here is a little bit of code to help you extract the month, day, and year from the current date. let flags: NSCalendarUnit = .DayCalendarUnit | .MonthCalendarUnit | .YearCalendarUnit let date = NSDate() let components = NSCalendar.currentCalendar().components(flags, fromDate: date) let year = components.year println(year) let month = components.month println(month) let day = components.day println(day)

I have been playing around with writing a Mac OS X app for stock trading. I was granted access to the trade servers API of a major online broker. The stream server API uses a data byte stream to send chunks of data for quotes. I needed this to track the live trades in real time so my app could calculate if it should buy or sell. The problem was…

Apple Push Notification Service (APNs) is a bit complex, but I will try to make it simple to understand from a business perspective. First you need to understand that when the notification is received on the device the operating system (OS) processes this data first and most of the time never calls your app code until you click the view button. The notification can contain a payload of data from…
