I am trying to set image to UIImageView. Its working well in older version.
In Xcode 9.4.1
But in Xcode 10
When I am trying to type name of image, image suggestion is not showing.
Even "Image Literal" is not working. Double clicking on above icon also not working.
Is there any setting in Xcode preferences?
How to enable image suggestion like before?
In Xcode 10 and Swift 4.2, only the code completion function (or auto-complete) of the Xcode IDE has been discontinued for the old way. Here is the new way:
Just type image literal and it will complete with default icon.
Double click on this icon and it will open the media library right side of it.
Just choose your image and it work like before!
Hope I am able to help you!

Code Completion for Swift image literals has been removed in Xcode 10. (38087260)
There seem to be some real issues with how Xcode 10 handles image literals, especially when the name you provide your assets doesn't align with the filename of those assets.
The following are the steps I've found will restore image literal previews.
Add an image via the media library picker.
If you have multiple resolutions for your image (e.g. #1x, #2x, #3x), Xcode will inconveniently drop them all into your code and throw an error to let you know you've done something naughty.
Delete two of the faulty image previews, if necessary. You may be left with a default image icon instead of a preview of your actual image.
Comment out the lines on which you're setting the image. You'll see the image literal references the filename of your asset rather than the name you've provided in the asset catalog.
If you've renamed your assets after adding them to your asset catalog, this seems to sometimes prevent Xcode from reading the asset appropriately.
Change the filenames to the appropriate asset names.
You can find the asset names in your asset catalog.
Uncomment the code and, if the default image icon is still visible, double click on the image icon. It should then display a preview of your actual asset.
You may also need to clean and rebuild your project.
use command + shift + M to popup the Media Library then Simply Drag and Drop into your Code

I'm attempting to use PDF files as icons in an app I'm working on. The issue I'm encountering is I'm getting inconsistent tint colors.
If I set a button image from interface builder, the icon image shows up black at runtime. Every time. Regardless of what I attempt to set from interface builder.
I tried setting my button icon image via code and instead of showing up black, it's white:
let myGraphicFile = UIImage(named: "myPDFImage")
let myButtonImage = myGraphicFile?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
myButton.setImage(myButtonImage, forState: .Normal)
From code, regardless of what I attempt to set the tint to, it's always white from code.
I discovered this post relating to Xcode 6.x, but I think it might be dated, as I'm able to partially do it, but I can't set the tint.
Use PDF in XCode for an AppIcon (.appiconset collection)
I create the icons in Inkscape, save as PDF 1.5. I add the file to Images.xcassets. In Images.xcassets' attributes inspector, I'm setting:
Devices to Universal
Scale factor to Single Vector.
Summary: I can get it to show up and scale properly, but it's either black from interface builder or white from code. I suspect I'm missing something re: how to save the file from Inkscape.
Thank you for reading. If you have any suggestions, I welcome them.
I have figured out how to create vector icons with Inkscape. When you use PDFs to display icons in iOS, you need to alter the Attributes Inspector for your icon in xcAssets as follows:
1) Drag the PDF into xcAssets
2) Set devices (I did Universal and it worked fine)
3) If your PDF icon is under 1x, 2x, or 3x size class, drag it to Universal and delete the rest of them.
4) Set Scale Factors to Single Vector.
5) Render as Template Image.
Once it's configured there, then you just treat it was you would any other image in interface builder. It's essentially the same thing I was doing in code, but I don't think it gets done in code...it's gotta be done on xcAssets where the image lives. It's my understanding iOS renders vector images for the size class at run time. I think by attempting to tweak it in code wasn't working because the image had already been rendered.
If anyone has any questions on this, I found this link helpful in resolving my issue.
Additionally, this post covers the topic, too. https://stackoverflow.com/a/25804358/4475605
So I tried creating a launch storyboard for my iOS 8 app using this tutorial
However, I only get a black screen when I launch my app. A single launch screen.xib file works perfectly, however, when I try to use a storyboard, it doesn't work.
I tried a storyboard with just a single view controller, but it still gives me a black screen, hence I believe the issue is with storyboard files in my setup. Any ideas?
[XCode version 6.4]
EDIT: So I just want to clarify that it is the launch screen that appears black. The main storyboard itself appears correctly when the app has finished loading
Read through the tutorial and tested it, and it doesn't say two things:
1: You'll need to add a UIViewController to your .storyboard file, and then select it as the Initial Controller.
2: If you wish to change more than just the launch screen, you'll have to go to the project settings and set the "Main Interface" to your corresponding .storyboard.
Once that is done, all you need to do is edit the UIButton/Label/etc connections to your ViewController classes.
EDIT:
For clarification, you can set a UIView as the initial controller by selecting it in it's respective storyboard file, then opening the Attributes Inspector. The option for 'Is Initial Controller" is towards the middle.
For people using UIImageView in the launch screen
Make sure that you are using the image name without the extension in the attributes inspector.
So for example, if your image file is named launcher.png, only use launcher as image name.
This will show the image as invalid (?) in the editor but will show correctly when run on device.
(Don't ask me why it works this way. Ask Apple.)
None of the answers have all the steps required, hence this exhaustive solution.
Storyboard
Start by creating the LaunchScreen.storyboard. Xcode > File > New > File... > Storyboard > LaunchScreen.storyboard and add it to all appropriate targets.
In this storyboard, create a single view controller of type UIViewController. Do all the magic your launch screen requires, then follow these steps:
LaunchScreen.storyboard > Show the File inspector > Use as Launch Screen
LaunchScreen.storyboard > View Controller > Show the Attributes inspector > Is Initial View Controller
Project > General > Deployment Info > Main Interface > LaunchScreen
Repeat for [iPhone] and [iPad]
Project > General > App Icons and Launch Images > Launch Screen File > LaunchScreen
If setup properly, your Info.plist should have LaunchScreen .storyboard, without the .storyboard under the UILaunchStoryboardName & UIMainStoryboardFile properties:
<key>UILaunchStoryboardName</key>
<string>LaunchScreen</string>
<key>UIMainStoryboardFile</key>
<string>LaunchScreen</string>
Notes:
This is not incompatible with having legacy images for older devices using Launch Screen File > Assets.
Pay special attention to LaunchScreen.storyboard and Main.storyboard. One is used for launch, the other for your app entry point. They both need to have Is Initial View Controller set.
In the storyboard, which you are using for launching, please make sure that you had selected the option of Is initial view controller for the very single view controller present in it.
I Belive I may have had a similar issue that required something a littel different to the above answers.
I created a new launch screen in a .storyboard file, then after it not appearing I resulted to a new .xib file which still did not appear when the app was launched.
I figured out that some of the images I had on my launch screen had an Outlet Collection to an old .swift file. After removing this from the LaunchScree.xib's the launch screen worked fine.
Notice the litte warning sign in the outlet reference ->
Make sure that you set your entry point and in your general info tap make sure that you have the view set to resize from nib. Also make sure that in your general tab the start up point is set. In the deployment info.
Hope this helps
Spent way too long on this, thanks Apple! I finally discovered that I had to delete the actual UIImageView in my view controller - not just the image - in order to change to a different image. Tried renaming the images, replacing them in all different ways, deleting caches, deleting the app from the device, doing a Clean before building. The original image was gone from everywhere as far as I could see but it would still appear. Finally I added a new UIImageView on top in the view controller and this took a new image. Then I just deleted the old UIImageView and all was fine.
The solution is use the image name without the extension png.
For example, if your image file is named "img.png", only use "img".
This will show the image as invalid (?) in the editor but will show correctly on running.
This happen because the LaunchScreen.storyboard accept only images inside Assets.xcassets and the way to refer the images inside Assets.xcassets is the name of the resource without extension.
I think that use the name without extension is a workaround that work.
I had the black screen instead of my splash after localizing my app. In Localization section of the File inspector of LaunchScreen.storyboard I had only one tick for one localization. So, I added a tick for the second localization and this fixed the issue.
Answers by #SwiftArchitect and others are good, but I kept getting the black launch screen instead of my launch storyboard.
The problem ended up being that my storyboard was losing its connection to my target.
When I created it, I moved it into a different group/directory in the Project navigator, to keep things neat. BIG MISTAKE! That disconnected it from the target... it didn't matter that the group/directory it was now inside of was connected to the target!
You can tell the difference in the dropdown menu located at:
Project > General > App Icons and Launch Images > Launch Screen File
When you open that menu, you should see your storyboard as a choice to click on.
Do not type in your storyboard name manually -- that's a sign that the target membership isn't right.
I am also trying to add a launch screen, and this procedure got it to appear (thank you!), but now the app hangs there, not moving on to Main.storyboard and viewDidLoad. I have this:
Launch screen interface file base name LaunchScreen
Main storyboard file base name LaunchScreen
If I change the second LaunchScreen to Main, I do indeed get to viewDidLoad and the app's main screen, but without LaunchScreen.
Both sim and device do this. What am I missing to get to Main after LaunchScreen?
when I load my application it shows a warning message that
"Could not load the "" image referenced from a nib in the bundle with
identifier "
I searched and confirmed all my images. But it still shows that warning.
Select your image(s) in Project Navigator.
Open the File Inspector.
Make sure you have the target selected.
I had the same issue when I Refactor to Storyboard. Apparently the Asset catalog does not transfer the image reference. To fix, see below:
You would notice that your ImageViews is empty from reference.
1 - Click on the ImageView
2 Go to the Utilities bar where you would see you asset image is unknown
3 - Change it back to you image asset
This should fix your error. Hope this helps!
There might be many reasons of this error. To fix this issue you can just follow below given step:
Go to product menu of the Xcode, select clean.
If still you are getting the error, then remove the images from your project and again add the images to your project.
while adding image into the project, make sure that you have selected the Project name inside the "Add to targets". And also enable the "Copy items if needed".
Please Refer below image for better understanding:
Just select the image in Xcode and in right side, File inspector, under 'Target Membership' make sure your project is selected.
Another thing you can do is delete and re insert your image and make sure 'Copy items if needed' is selected and 'Add to targets' your project is selected.
Click on the image file in your Xcode navigator.
Once selected, go to the right side bar (of XCODE) which is
utilities and under file inspector, scroll to target membership and
select your project target file.
Then build and run the project again.
Xcode9 beta2 release note:
Jpeg assets in asset catalogs are not found on iOS 10 or earlier for apps built with Xcode 9. APIcalls for accessing the image such as UIImage.imageNamed: return nil. (32524123)
Workaround: Use png resources or limit app testing to devices running iOS 11 or later.

Jpeg assets in asset catalogs are found on iOS 10 or earlier for apps built with Xcode 9.(32524123)
For those that are getting this error while developing a cocoapod
I was trying to use an image from my pod's bundle, thats inside a .xcassets file, in the storyboard. It would show fine in the storyboard but when i ran the app it would crash saying it cant find the resource.
I changed my podspec to include s.resources as well as s.resource_bundles
s.resource_bundles = {
'SDKRes' => ['SDK/Assets/*']
}
s.resources = ['SDK/Assets/*.{xcassets}']
Then it was able to load the resource properly from the storyboard
You can try opening your storyboard or nib as Source Code and then "Find" the image name in it, see if it exists but already invalid in your project, probably you have deleted or changed its name, and now it doesn't seem valid.
I have just updated to XCode 9 and it started giving me this issue. I created a new Image Set in the Assets section and added the images I wanted to this, then re-added them to my tab bar images with custom names and it worked fine. Hope this helps!
PROBLEM
This happened to me seemingly out of the blue on a tab bar controller with icons for each tab. The storyboard was still showing my image icons and the assets existed with the expected names.
MY FIX
Select the tab bar icons in their respective view controller and reassign the image like you did the first time.
This happened to me as well. I was doing everything right when adding the image but for some reason it was not working. I had to click on the image again once added, and then on the right toolbar under "Target Membership" I noticed my project was not selected even though I was selecting it when adding the image. I selected it here and everything worked fine.
I got the same error message (in XCode 8), even though the app ran fine (in the simulator and on the device).
I found the problem: In my storyboard, using the document outline pane, I clicked through every single UIImage, and looking at the attributes inspector for each UIImage - in the Image View section - found that one UIImage had a blank file name (instead of the .png file name containing the image). Reselecting the .png file name from the dropdown box fixed the error message.
I have fetching same issue in xcode 9.
just tick on target membership
I pulled my hair out over this issue for hours and none of the solutions in this thread worked. The problem, in the end, was that the Xcode project files were stored on a Google Drive file stream. As soon as I moved it to the local drive or iCloud it worked fine.
My case was a bit different. I was using an old IBDesignable element which had some property of setting an image directly from the storyboard. Since that element was old, hidden and unused the images it had were not present in my assets folder.
Now Xcode won't be able to search this image since it is not in the project anymore. But if you search in the finder, inside your project, you'll find the XIB/Storyboard in which it is mentioned. From there you can find it manually by opening that XIB or Storyboard as source code and search. Once found either replace them with a new image or remove the unused element.
Look into storyboard file you'll see a question mark icon on any of the imageView (as shown in screenshot below) or UIButton image.
Just correct it and the warning will be gone.
Hope this helps
My guess is that you have an image in the Project Setting->Build Phases->Copy Bundle Resources which loses its reference and appears in Red text color. Remove this image from there and re-add.
This happens often due to relocate the image file after adding into project where image was added as a reference instead of a copy.
May be this can fix your issue.
Urughhh. I tried to fix this with all the above solutions, but nothing worked. What finally worked was:
Delete image from your project and select Move to Trash
Clean project
Close and restart XCode
Rename your image filename so something other than the previous name
Add new image to your project
I was facing the same problem, I solve it by deleting folder and create again and past all images then add reference again.
Based on what #hstdt posted above, it made me think I should check that my image is a filetype that doesn't have any bugs related to it. (https://stackoverflow.com/a/44558948/6804257)
I was using a .gif. I got rid of that image and instead used a .png. Now it works.
Had the same issue and none of these answers worked for me. Instead I restarted the mac and iPhone I was working with and then everything started to work fine again. 🤷♂️
My case is difference. I have more one assets folder. So I added to the wrong one.
Just remove and add to the right.
In my case,removing and adding the assets folder from the target fixed the issue.
Xib sets a wrong name for folder reference images. For example I have the folder like Menu->icon.png. Xib sets the "icon" name for the image. It should be "Menu/icon". So do no set images in xibs if you use a folder reference images.
Since xcode 6 didn't offer an empty application any more, I manually created one by deleting the Launch screen interface file and the Main storyboard file base name in the info.plist file, and deleted Main.storyboard and LaunchScreen.xib then. Considering that I'll drawing the UI by myself, I created a view controller without an xib file. But when I ran the app, there are black bars both on the top and the bottom. I checked the [[UIScreen mainScreen]bounds] and found out that the bounds was 480*320.
I've checked on google and there were suggestions like adding png pictures or creating a xib file, but I really wonder why the property bounds didn't get the right size.
I have met with this problem, it's because you delete your "Launch screen file" and didn't set in general tab "Launch image source".
So you need to make .xcassets file, after right click inside .xcassets file you create "New Launch Image" with name something like "LaunchImage" and set images for appropriate sizes. After that in general tab you set "Launch image source" property name with your "LaunchImage".
Step 1:
Step 2:
Step 3:
A better approach would be to keep the storyboard and everything else Xcode sets up for a single-view app, and then build out your UI programmaticly from the ViewController. That way, you inherit all the automagic stuff the SDK does during startup.
I can't tell you exactly what this automagic stuff is; but, I'm pretty sure your bug would go away if you adopted this approach.
