iOS 7 introduced Dynamic Type which allows the user to specify the font size in Settings. The easiest way to support dynamic type is to use one of Apple’s pre defined Font Text Style’s below. Swift 3 and Swift 4 UIFontTextStyle.title1 UIFontTextStyle.title2 UIFontTextStyle.title3 UIFontTextStyle.headline UIFontTextStyle.subheadline UIFontTextStyle.body UIFontTextStyle.callout UIFontTextStyle.footnote UIFontTextStyle.caption1 UIFontTextStyle.caption2 Swift 2.2 UIFontTextStyleTitle1 UIFontTextStyleTitle2 UIFontTextStyleTitle3 UIFontTextStyleHeadline UIFontTextStyleSubheadline UIFontTextStyleBody UIFontTextStyleCallout UIFontTextStyleFootnote UIFontTextStyleCaption1 UIFontTextStyleCaption2   Here is a code example in Swift 3 or Swift 4 of using the Headline font style.

These instructions are for localizing the information contained in the Info.plist. This includes the app’s name which is displayed on the user’s home screen under your app icon. In Xcode go to File, New, File.. Select iOS (or the platform you are working with), Resource, Strings File, Next. Name the file InfoPlist.strings (case sensitive). If you only plan on having one App name for your project then I recommend placing the file in the same directory as your Localizable.

Localization is the translation of the app’s user interface into locale specific languages.  In order to support localization we will use a strings file. Creating a Localizable.strings file I like to place the strings file in its own folder called “Resources”. In Xcode, Select “File”, “New”, “File…” In the template picker select the “Resource” for the appropriate OS.  Select “Strings File”. Name the file “Localizable.strings”.  This is the iOS default naming convention, don’t name it something else unless you want to refer to it by name every time you need to reference it.

Promo codes allow you to give away your paid app for free. They are mainly used for sending your app to journalists or bloggers so that they can review your app at no cost to them. You can also send them to your friends or reward those who made some contribution to the apps development. Developers can generate up to 100 promo codes per version. Each code expires 28 days after generation or when you release a new version of the app, whichever comes first.

Is Xcode giving you the error in Localizable.strings “Read failed: The data couldn’t be read because it isn’t in the correct format.” but it isn’t telling you what line the error is on?

In Apple’s new tvOS, data saved in core data is not persisted but is only cached. The tvOS may delete the data stored in core data when space is low. From https://developer.apple.com/library/tvos/documentation/General/Conceptual/AppleTV_PG/ Local Storage for Your App Is Limited The maximum size of an Apple TV app is limited to 200 MB. Moreover, your app can only access 500 KB of persistent storage that is local to the device (using the NSUserDefaults class).
