什么是资产目录？ 我看不到任何错误

Question

I read a lot of post, but I'm not able to solve. ios appstore icon are w/o alpha channel, but I still get the error: "Invalid App Store Icon. The App Store Icon in the asset catalog in '--name--.app' can't be transparent nor contain an alpha channel.
I'm sure I remove alpha channel from resources, but I still get the message,

After hate tried in every way to edit icon-1024.png, I ran (with ImageMagick)

find . -name "*.png" -exec convert "{}" -alpha off "{}" \;

at root of the project, so I'm quite sure; but error remain...

你应该把它压平，而不是使用

convert -flatten
