[SOLVED] Apple Watch AppIcon for Long-Look notification is missing in Assets.xcassets

Apple Watch AppIcon for Long-Look notification is missing in Assets.xcassets

When uploading a new build to Appstore Connect, it gives a warning that "Missing Icon".

So I went to Watchkitapp's asset catalogue and I can't find the long look notification icon anywhere to be added? Where as short look notification can be seen. I tried creating a sample new project for watch and found the same.

What am i missing? Where to add the icon for long look notifications?

Solution

This was an issue with Xcode 10 and it was perfectly fine with Xcode 9. The solution to this issue is:

Go to your xcassets in your watchapp extension and then to the finder via right clicking it.
Close the Xcode project
There will be file named as "Contents.json". Open that file in some editor.
Add the PNG's of those resolution that are missing and note down the filename of those.
Add a dictionary those are missing like longlook and quicklook aka shortlook and type the file name correctly to match the Appicon name of yours which you have added now.
Save the json file and open the Xcode project and go to the xcassets and then you can see like the following image:

It will show as warning which is perfectly fine due to the issue in Xcode 10.
Now you can upload the build to Testflight and there will be no warnings for your build.
I have attached my contents.json file and image of how the assets folder will look like for your assistance.
