Question

I\'m trying to submit an update to my App to include Apple Watch capabilities, however whenever I validate the build I get the errors detailed in the screenshot below. Looking a

Answer 1

I just used this template and everything went smoothly, just make sure your images don't have alpha channels.

Answer 2

I had the same problem, none of the sollutions above worked for me.

Instead of submitting the app, I exported an IPA, and had a look of its contents. Turned out there was duplicates of my icons in there, but named differently.

I renamed my files according to the files I found, drag and dropped them to their places in AppIcon, archived, submitted and IT WORKED!

Proper naming of the WatchKit icons:
AppIcon24x24@2x.png
AppIcon27.5x27.5@2x.png
AppIcon29x29@2x.png
AppIcon29x29@3x.png
AppIcon40x40@2x.png
AppIcon44x44@2x.png
AppIcon86x86@2x.png
AppIcon98x98@2x.png

Answer 3

I had the same error but it ended up that my 27.5x27.5@sx.png image was 56x56 but apple needed it to be 55x55

Answer 4

I got the same problem and wasted me almost whole day to fix the issue. Before I figured out the solution, I tried every advice you guys posted but failed in the end.
Here is my stupid way to fix it: ALL the icons in the App Icon should have the same color profile, in my case, two of icons are different from others. After I changed the other two color format, it works.

Answer 5

For me, the issue was that I still shipped the watchOS 1 Long Look icon (44X44@2x) even tho I no longer supported watchOS 1. Once I unchecked the bod for watchOS 1.0 in the assets and deleted the no longer needed icon, I had no problems.

Answer 6

Okay I finally figured it out myself: Here is what I did, and along with about 30 attempts to submit it, I finally don't have issues with this. Only the last thing I did for 100% made the difference, but I thought I would share because this problem was about a 6 hour issue (along with other junk I had to fix that normally I wouldn't for a normal universal iOS app)

1) Deleted all my derived data by going to Library/Developer/Xcode/ or something like that.

2) Clean, Clean Folder

3) Rename all icons for Watch to these names:

AppIcon24x24@2x.png
AppIcon27.5x27.5@2x.png
AppIcon29x29@2x.png
AppIcon29x29@3x.png
AppIcon40x40@2x.png
AppIcon44x44@2x.png
AppIcon86x86@2x.png
AppIcon98x98@2x.png

4) Use one Images.xcassets file. This file has 3 main objects in it: a) Icons for iPhone and iPad b) Icons for Watch c) Splash Screen Images for iPhone and iPad

5) Clean up the Images.xcassets by tapping show/hide Utilities on the top right of the window in Xcode. (only have icons for iPhone and iPad in the first object, only have Watch Kit icons in the second object). Also, remove CarPlay icons

5.5) Also goto the regular app's target, in the general section, set the app source icon to the one with only the iPhone/iPad icons. Then goto the watch kit app, and set the app source icon to the one with only the watch kit icons

6) Go through each folder for each of the 3 targets and go into the info.plist, and remove all of the icon keys. There were 1-3 of these in each info.plist. I just deleted them. The info.plist can be found by tapping on the target, or looking in your folder hierarchy. These are the 3 info.plists you need to look through: a) Regular app's plist b) watch kit extension's plist c) watch kit app's plist

7) Finally, I went into the watch kit app's plist one last time and added a new key: CFBundleIconFiles When I added this new key, Xcode changed the name to Icon Files. This is an array which I added one at a time each of the watch icon file's names: AppIcon24x24@2x.png AppIcon27.5x27.5@2x.png AppIcon29x29@2x.png AppIcon29x29@3x.png AppIcon40x40@2x.png AppIcon44x44@2x.png AppIcon86x86@2x.png AppIcon98x98@2x.png

Finally! Success! Hopefully this helps everyone out who is stuck with this lame problem. P.S. Sorry if there are formatting issues. Stack thinks I am writing code so had to indent, when I wasn't.
