Since upgrading to XCode 3.2, InterfaceBuilder doesn't play nice. All of my image links are broken in IB but they'll show fine when I compile. When I go to the combo box to select an image for my UIImageView, it doesn't have the image files I've added to my app.
I also can't create a new .nib and associate it with a class I've written. Like images, my custom viewcontrollers aren't available to pick from.
I'm going to try a reinstall but I was curious if anyone's dealt with this?
I gave up trying to fix and resorted the classic workaround. Started a clean project and schlepped everything over. Things are fine...for now.

I'm very new to Xcode and Swift, so for now I'm creating a UI that requires an image to appear on the screen. I would like to add the image to the LaunchScreen.storyboard file in Xcode. Can anybody help me?

Images are typically stored in .xcassets files, which show up as folders in your project. Your project probably already has one called Assets.xcassets, and you can just drag and drop images into that file. Then you can add an image view to your LaunchScreen.storyboard and set it to use the image you just added.
Beyond that, let me suggest that you go through some of Apple's SwiftUI tutorials. They'll help you learn about Swift, but you'll also get a lot of exposure to just using Xcode. If you have to figure it all out on your own, it'll take a lot longer.
I have a Android background and now try to code for iOS.
I use Swift as the language and it works really good so far. Now I am getting some troubles to get my layout to work on different screen resolutions that means different iPhones.
I am using storyboards for my ViewController and for now everything worked well except getting UIImageViews to look the same on each iPhone.
I tried now for 2 whole days with dozens of different approaches to get my layout work, but without any success. If I place a single UIImageView on my layout I am able to set the constraints so that it looks the same on each iPhone. Once I place a UIImageView on top of my first UIImageView it destroys everything. I won´t tell you here what I already tried, because it was a lot and nothing worked for me.
I need really some hint or just someone who could just try it on his Storyboard and tell me how he achieved it to get it work. I am using Xcode 8.2.1.
This is how it should look like (iPhone 7):
This is how it looks on a iPhone 4s --> wrong! Proportions are not the same!
It's need more params and maybe UIStackViews.

I hope you can help me with my actual problems with designing an iPhone-App in the latest xCode version.
Here´s what I find a bit strange:
I designed a new project with a Storyboard and a Navigation Controller. Then I placed Objects like UILabels, ImageViews and so on. No when I run the Project in the simulator (as well on the iPhone) I noticed the following: When the App loads all the in the View placed objects fall down from the top to take their defined place. It takes maybe the quarter of a second, but its clearly to see. It also happens on all other views initiated from the root view controller
So, what do I have to change that everything is at it´s fixed place without to fall down from the top at the start of the app?
I hope I described it good enough. Actually I have no idea what´s going on there. I hope you can help me to fix this "problem". I´ve written some small Apps before, but I´ve never noticed a behavior like this.
Got the solution: I´ve had to remove the animations on the main view... now it works proper! :-)
I am dealing with this really really annoying bug in X-Code where it seems to save images to some type of memory that seems impossible to clear.
I have replaced a bunch of images in which I am creating a clock animation however when I try to play the animation it showes all the old images, I have tried cleaning the app and still they continue to show even though I have deleted the images.. So then I tried changing the name of the images along with the code where they were getting called and now I'm getting a bunch more errors, So I'm just woundering if anyone knows how to get around this problem of xcode caching images.
You need to clean the build or delete it from the device/simulator. That usually takes care of it if you're sure the files are named correctly. Also make sure that you're using the correct case in your filenames, that messed me up a few times. :)
In the XCode explorer, right click on the image, use "Show in finder" and make sure they refer to the images you want.
Try using the Clean option from the Product menu in XCode.
This might come across as a very silly question. I am trying to place an image behind my first "Hello World" app on iphone, since this morning. I tried doing so using Interface Builder using UIImageView object from library and also tried doing so programmatically.
Googling hasn't be much of an help either. Can any one please demonstrate a simple app that shows how to display an image in an iphone app, in background and/or in foreground?
The step you're missing is likely adding the image to the project.
Drag an image from the finder to the Resources section of the project outline. Xcode infers the action from the file type, and images will be copied to the Resources folder. You can check it out in the Targets section of the project outline, if you disclose your Hello World target you'll see the different build phases, including a "Copy bundle resources" build phase.
Anyway once the image is added to your project, the UIImageView inspector image name will autocomplete your image name, and all should work. No code needed.
You could try to add a UIImageView, in IB, to your view and arrange it to the background (behind all labels, etc)
edit: I just realized, you already tried it in IB. I was ignorant, I'm sorry.
The thing is, I do this same trick myself, and it works. If you add a UIImageView to your view in IB, what happens? Does it stick to the foreground? If so, you can re-arrange the position of the object by using the 'Layout' menu.
edit2: I just searched the iphone reference library, and the "Hello World" example also shows how it is done. (http://developer.apple.com/iphone/prerelease/library/samplecode/HelloWorld/index.html)
