#Xcode app icon code#
I had the same problem but I fixed it following the next steps:ġ) Add this code to Podfile: post_install do |installer|Ĭopy_pods_resources_path = "Pods/Target Support Files/Pods-IconTest/Pods-IconTest-resources.sh" It should be a bug in CocoaPods, as disccussed here I say theoretically addresses because I've tried implementing both of these solutions, and neither of them resolved the issue on the project where I've encountered it. See discussion with possible temporary fix here and a pull request that has been created for Cocoapods that theoretically addresses this issue.

The most obvious thought is that app icons with transparency might be rejected, but I do not believe the icon images I was using contained transparency and I tried to eliminate this in my testing above.Ī completely separate cause that has been reported for some users is related to CocoaPods integration. Perhaps there is something within the png specification which is a valid png, but not an acceptable app icon to Xcode 9. Creating a new AppIcon resource, and inserting the Sketch-created images resulted in the app icon still working.Īll of the above suggests that there is something in Xcode 9 which rejects or fails to use previously working app icon images, and that some processes to create app icons that previously were fine produce images that Xcode 9 cannot use.Re-creating all the icon sizes with a different process, via Sketch, and inserting those icon images into the same AppIcon resource resulted in the app icon working.Inserting those re-created icon images still resulted in a blank app icon. Ensured that my source image did not contain transparency. Re-exporting all the icon sizes with my usual pre-processing app Prepo.I therefore tried various steps to resolve this: Creating a new AppIcon resource, and inserting the original app icon images likewise led to a blank app icon.Ĭombined together, the points to this stage suggested perhaps there was something wrong with the image files themselves.Copying the image files from the non-working to the working AppIcon asset resulted in the working one now failing also.An AppIcon resource copied in from another project where the AppIcon worked, resulted in the AppIcon working in this project, suggesting there was something wrong with the specific original AppIcon resource that wasn't working.A range of experimentation found the following: In my project, I found that a previous AppIcon resource that was working fine no longer resulted in an app icon being rendered.
