Swift playgrounds with UIImage

Question

I am working with Xcode 6, and I\'m trying to recreate the code demoed during session 401 \"What\'s new in Xcode 6\". I\'ve added an image to Images.xcassets (called Sample)

Answer 1

Using XCode 6.3.1 and running playground in full simulator (iOS) I had to do the following:

1. Find your .playground file in finder
2. Right click it -> show package contents
3. If it doesn't already exist, create a folder named Resources inside the package
4. Add your image there

Then just instantiate with let i = UIImage(named: "filename.png")

Answer 2

As of Xcode 8 Beta 1, you can use Image Literals to import an image into an Xcode playground:

Start typing image to add an image literal:

Select (or browse for) your image:

See your image inline:

Answer 3

Look at the iOS Developer Library->Playground Help and search"Resource Files" and you will find the answer

1、Open the .playground

2、Show the Project navigator by selecting View > Navigators > Show Project Navigator.

3、Drag the images to the Resources

Answer 4

However, I can't get it to work like the demo. Am I missing something?

I'm not sure where you need to put the image to refer to it using only the name, but I got the same code to work by specifying the full path to the image, like:

var sample = UIImage(named: "/Users/my_user_name/Desktop/Image1234.jpg")

Having to use the full path seems more complicated than it should be, but it works and it let me move on to more interesting problems.

Answer 5

1. Open the .playground file in Finder.
2. Create a folder called Resources next to it.
3. Add any images you want to this folder.
4. In the playground press opt-cmd-1 to open the File Inspector. You should see the playground on the right. If you don't have it selected, press cmd-1 to open the Project Navigator and click on the playground file.

5. Under 'Resource Path' choose 'Relative To Playground'
6. Click the folder icon underneath and choose the Resources folder created earlier.

You should now have a bundle that you can use with the standard NSImage(named:"filename_without_extension"):

Note: Because Xcode will frequently overwrite the .playground folder, I recommend using this method so the resources folder isn't getting constantly deleted and re-created.

Answer 6

On the iOS playground with XCode 6 beta 5 (and probably later) you can see the image inside the bundle:

1. In the playground press Cmd+Opt+1 and click the arrow under the Resource Path (this will open Finder)
2. Put your picture to this folder

3. Access it with either

   let img = UIImage(named: "logo.png", inBundle: NSBundle.mainBundle(),
                     compatibleWithTraitCollection: nil)
   

   or

   let path = NSBundle.mainBundle().pathForResource("logo", ofType: "png")
   let img = UIImage(contentsOfFile:path)
   

   or in Swift 4:

   let path = Bundle.main.path(forResource:"logo", ofType: "png")
   let img = NSImage(contentsOfFile:path!)
