Originator:futuretap
Number:rdar://33058060 Date Originated:29-Juni-2017 08:03 PM
Status:Open Resolved:
Product:Developer Tools Product Version:9.0 beta 2 (9M137d)
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
When iMessage.xcassets contain at least two app icon sets with the App Store image filled out, building the app fails with an ibtoold crash.
The same project could be built using Xcode 8 just fine.

Steps to Reproduce:
Build the attached project using Xcode 9.

Expected Results:
It should build successfully.

Actual Results:
It fails with this error message:

Version:
9.0 beta 2 (9M137d)

Notes:
When I remove the second app icon, it doesn't crash. Having two app icon sets is useful to differentiate debug and release versions in the app icon.

Comments

The bug still occurs in iOS 11.0 beta 3

Only the error message changed:
