Vector graphics in iOS

In past, designers had to create multiple versions of the same asset (1x, 2x, 3x) to satisfy multiple screen sizes. Using vector assets can save you time because you only have to generate the asset once. You just need an.xcassets file in your project for storing your images. In there, you can declare image sets to be “Vectors”.
A vector file contains a lot of metadata of an asset that tells the system how to render it's contents, independent of the screen's resolution. This also means that whenever we get larger screen resolutions, Xcode will be able to scale up your images from your already existing vector PDF for you, giving you automatic support for future devices for free.

Steps:-
Select “New Image Set” in your XCAsset.Select the Attributes Inspector in Utilities panel.Under the types drop-down menu, select "Vector"Drag and drop your vector PDFUse the Xcode image catalog image set as you would with any other image. For instance, calling --imageNamed: in code, and pa…

Return multiple values from a function in objective C

func getData()->(Int,Int,Int){//...code herereturn( hour, minute, second)}You can't do that in objective-c. Best option is using parameters by reference. Something like this.

Disabling print for Production In Swift Project

Then in your code you can define a DLog() function and only print your message if the DEBUG flag is set:
func DLog(message: String, function: String = __FUNCTION__) { #if DEBUG     println("\(function): \(message)") #endif }
