Yes, my problem really is that simple. How the heck do I get my app to use the icon file or asset catalog?!
System info:
Xcode 6.1.1 (6A2008a)
app target OS X 10.10
OS X 10.10.1 (14B25)
This is my first OS X app but I have several years' experience developing iOS apps.
Steps to reproduce:
open Xcode, start an entirely new cocoa application project
not sure this matters, but i specified my new project not to use storyboards or core data
drag a .png file from my local directory into the project structure, and make sure (a) it ends up in the build target and (b) the file copies into the project's directory
drag the png into the Images.xcassets catalog under any/all of the sizes classes for AppIcon.
build and run
Expected: app in dock and tab-switcher has the new icon.
Actual: app in dock and tab-switcher has the default "blank page with instruments A on it"
Ok, maybe that's a DEBUG thing.
archive the project, show in finder
Expected: app in Finder has correct icon
Actual: nope. It should be noted however that Xcode's Organizer shows the correct icon, and there does exist a file Contents/Resources/AppIcon.icns. Contents/Info.plist specifies that the Icon File is "AppIcon".
grrr. Let's try without the asset catalog.
in the target's General settings, under App Icon, select "don't use asset catalogs"
delete Images.xcassets
In Info.plist, in the line for Icon File (CFBundleIconFile), specify the icon's name (in my case "AppIcon"). The documentation clearly states that
The system looks for the icon file in the main resources directory of the bundle.
File extension is not required here.
build & run. also archive, to save time later.
Expected: app icon in dock and tab-switcher is correct.
Actual: nope
Expected: archived app has correct icon.
Actual: nope, but the archived product did have the correct png file in Contents/Resources.
What am I missing?!
I've tried this with .png app icons and a regular .icns file (generated by Xcode via an asset catalog). I've tried excluding and including the file extension in the Info.plist. Why is this so difficult?
Edit: Clean, Clean Build Folder and deleting the Derived Data folder did not help.
So I found the answer through the help of a commenter: I had to fill all of the xcassets/icns slots with images of the exact dimensions.

How can I set a custom icon (using a .icns file) during a script phase of an Xcode build targeting a non-app bundle?
We are making audio plug-ins, and would like to have our own icons instead of the default ones for our .vst3, .component, and .aaxplugin bundles.
I had some very old script that used to do this, but it relied on the old Rez utility and doing something I don't recall with a specific portion of the resource fork. Now, with bundles, I can't find the script I need to add to insert the icon and make it actually show up.
I have set the CFBundleIconFile string in the plist file to MyIcon.icns, and the script phase copies the MyIcon.icns file to the Contents/Resources folder, but it still does not show up in Finder with our icon. (If I change the plug-in extension to .app, our icon DOES show up, but then I can't change the bundle back to .vst3... it keeps the .app extension once that is set.)
I'm using XCode and Appcode for developing.
In Appcode, accidentally I deleted the .app file from the Products folder.
After that I can build the project successfully in both IDE, but can't run on simulator or device, when the build finished, nothing happening.
The .app file created on the derived data directory fine, like earlier so that's not the problem.
If I check the debug scheme in XCode, on the Executable list None is chosen, if I browse the generated app in the derived data directory and set that, then works fine, run on simulator and device too, but the app file not shown in the Products folder and after a restart, XCode set the Executables back to None, which is annoying.
How can I set back the .app file to show in the Products directory in XCode and work like earlier?
I was able to delete the "product" file in my own test project by going to the Project Settings and then clicking on the app under "Targets" and touching the "Delete" key.
To create a new Target, go back to Project Settings and click the "Add Target" button.
Normally, this means you need to reset all of your settings, but if you have the original target's Info.plist (settings) file around, you may be able to pick up some of your previous target's settings from there.
I also faced the same issue.
If we are building for the SIMULATOR - then the Target file still "not-included". Change from the top build actions for - ProjectName>iOS Device (instead of the ios Simulator) then the project target file gets generated and is included in the project folder hierarchy.
There is no need to run - just rebuild and that should do the trick
I have just written my first "hello world" MacRuby app using XCode. I would like to add a custom application icon. I thought I did this correctly, but when I build my app (using Project > Archive > Application) it builds it with the default Mac Application icon. To import my icon (518 x 518 px PNG), I right-clicked the "App Icon" button and selected the file to copy into my project. I can see the file, but it obviously isn't displaying when I open the app.
What did I do wrong? How can I fix this?
I haven't used MacRuby, but there are two things you have to do to display the right application icon. First, you must convert the PNG file to an icon file. Use the Icon Composer application to convert the PNG file. Icon Composer comes with Xcode. You can find it in the following location:
/Developer/Applications/Utilities
Second, add the icon file to your project. After adding the icon file to your project, you should be able to set the application icon for the project.
I have been learning a lot about writing Objective-C code and designing in Interface Builder and I wanted to set icons for my simple programs.
I added the same JPG to all the size fields in Icon Composer and got an ICNS, but I couldn't figure out how to add it to the project.
Thank you in advance.
Since Xcode 4.4 Icon Composer is no longer the recommended way to create icons and is no longer included in the standard install of Xcode.
Due to the introduction of Macs with retina display, it is now recommended to provide high resolution versions of all graphics including app icons.
To give your app an icon under Xcode > 4.4 do the following:
Create a folder [IconName].iconset in Finder
In this folder place your icon as png files. You'll need the icon in
sizes of 16px, 32px, 64px (retina only), 128px, 256px, 512px and
1024px (retina only)
These icons must be named with the pattern icon_16x16.png,
icon_32x32.png, icon_128x128.png and so on
To support retina displays you must also add icon files with double
resolution, named icon_16x16#2x.png (with size 32x32),
icon_32x32#2x.png (size 64x64) and so on up to icon_512x512#2x.png (size 1024x1024).
drag this [IconName].iconset folder to Xcode (copy if necessary)
in the info.plist file set the "CFBundleIconFile" (Icon File as Key) value to
[IconName] but without the .iconset extension
Annotations:
it is (currently) not required to provide the #2x icons
it will (usually) also work if you don't provide every icon file
the iconset folder should not contain a icon_64x64.png file. the 64px icon is only for the retina version of the icon_32x32
Update:
In the end your .iconset folder has the following 10 items:
icon_16x16.png
icon_16x16#2x.png
icon_32x32.png
icon_32x32#2x.png
icon_128x128.png
icon_128x128#2x.png
icon_256x256.png
icon_256x256#2x.png
icon_512x512.png
icon_512x512#2x.png
Official guide:
https://developer.apple.com/library/content/documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Optimizing/Optimizing.html
Additional information:
To convert the iconset folder to an icns file, run the following command on the terminal:
iconutil -c icns [IconName].iconset
where [IconName] should be replaced with the prefix of the iconset folder. You now have a file called [IconName].icns. In Xcode 4.4, in the Target Summary, right click the question mark for the icon, then select the icns file. You should then see the question mark get replaced with the icon.
As of Xcode 7 (not sure when this was originally introduced), you can use the Assets.xcassets file for app icons. This file is included by default for new projects.
Simply:
Go to your target's settings and ensure that under General, App Icons the Source is set to AppIcon.
Add all 10 png icons to your Assets.xcassets's AppIcon image.
Delete derived data if you have launched the app before, otherwise it will continue to show the default icon.
Run the app; it should now show your icon in the Dock, Application Switcher, and anywhere else it should appear.
Follow these steps to add an application icon to your project. This is the icon that will be show by the MacOS in the doc bar and alt-tab display.
Create an icon .icns resource file
Place it in the "resources/macos" folder
Add it to the resources group in the xcode project
Edit the Info.plist file and change the "CFBundleIconFile" value string to "icon"
Also, img2icns tool can come handy to convert images to an icon.
It's easy
Use automatic tool (Such as IconFly) for create correct ICNS or iconset with all necessary size.
Then drag and drop created ICNS or iconset to Xcode.
in the info.plist file set the "CFBundleIconFile" value to [IconName]
Steps to add an application icon to your cocoa project.
Find 'Icon Composer' from spotlight.
Drag and drop the icon(name should be like imagename.icns) in the given boxes.
Select one box and save it.
Drag and drop the saved image in the Resources folder of your application.
Select target-->right click on project name-->Select GetInfo.
In Properties enter the name of 'Icon File'.
Now Clean Build and run your application.
Xcode 8.2.1
Convert .png 👉.icns via IconMaker
Add the AwesomeApp.icns file in the same folder as info.plist
Drag AwesomeApp.icns file into xcode in the same folder as info.plist
In info.plist set icon: to AwesomeApp.icns
Step 1: Get iconfile name from info.plist and place icns(icon file) folder in SourceCode/resources folder
Step 2: And same thing goes for xcode,you have to copy all images from xcode using copyallframeworks or copyall resource file in your xcode and build the app again.
I have created an xcode project. Now I want to give .app file to my friend to use that application. From where do I get this file? How to install this .app file in his Applications folder using an installer package?
You can find the .app file here:
~/Library/Developer/Xcode/DerivedData/{app name}/Build/Products/Deployment/
Credit for the path location goes to this answer
SIDENOTE: I had a lot of fun trying to get this into my iPad after that. It worked however. Using Snow Leopard + Xcode 4.2 + iPad with IOS 5.1.1 :) - I used the iPhone configuration utility to get the app into the ipad (you have to add the app, then click on the device, then click "install" behind the app you just added in the "application library" of iphone configuration utility) and had to create a Distribution Provisioning Profile and get the WWDR certificate and finally change the build settings in Xcode after all the certificates were in place. See here
But after much fun I am now looking at my first app on my iPad :) - btw, for getting apps into the app store you need to create a app store Distribution Provisioning Profile, while for ad hoc installs like these you create an ad hoc one. There is a bit more to it, but I think these are the most important and tricky steps. Enjoy.
PS. Just remembered that you also have to set the build type (top left of Xcode) to "iOS device", otherwise it will never sign your application. So the path name above only has limited value: yes, it will have the .app file in it, but no you can't upload it (at least not using the iPhone configuration utility) since it is not code signed - you will get an "Could not copy validate signature" error. So change it to "iOS device" and build (remember to select the right certificates in the build section of Xcode as per the url info above). In that same build section, you can also set the "Installation Build Products Location" to a different path, so that you can determine where the .app (the one that is properly code signed) ends up.
Xcode 12.5
Can be found in the following directory ->
~/Library/Developer/Xcode/DerivedData/{app name}/Build/Products/{scheme}-iphonesimulator/{app name}.app
Build a release version, and the .app file is under build/Release folder of your project. Just copy it to Applications folder of your friend's machine. I don't think you need to build a installer.
xCode window tab
Organizer
Right click to the archive you want to get app
Show in finder
Right click to (ProductName….). xcarchive file
Show package contents
Products
Applications
Finally - THERE IS YOUR .APP PROJECT FILE !
The application will appear in your projects Build directory. In the source pane on the left of the Xcode window you should see a section called 'Products'. Listed under there will be your application name. If you right-click on this you can select 'Reveal in Finder' to be taken to the application in the Finder. You can send this to your friend directly and he can just copy it into his Applications folder. Most applications do not require an installer package on Mac OS X.
Under Xcode 4.5.2, you can find the .app file in this way:
Select Window > Organizer in the Xcode's menu(or just press 'Shift+Command+2')
Select your project on the left side of Organizer, and you will find the Derived Data path on the right side. Just click the mini arrow in the end of the path, this will open Finder at the path.
In the Finder, click "Build > Products > Release", you will find the .app.
I know as for Appium Mobile Automation you need .app file to run ios app on Simulator.So as like me many of you face this problem.
So I explain how to create that .app file and where it is located.
1.Open Xcode.
2.Click on your sample project.(If you don't have then click on create new xcode project)
3.In left panel inside screen you will see products folder then click and expand that, you will see the list.
Then right click on .app file and click on Show in Finder and thats your .app file. Now you can copy or use that path in capabilities for appium desktop or in framework.
Xcode 8.1
Product -> Archive
Then export on the right hand side to somewhere on your drive.
In Xcode 7 a quick way is to use Product > Archive. It's probably not a signed copy for submission but it's good enough to give to somebody else for testing.
In the navigator (left pane), expand the group "Products" and right-click on the .app file and choose "Show in Finder". There it is! :)
