当我尝试向Itunes Connect提交应用程序时，我得到了以下错误。
iTunes Store Operation Failed
Error ITMS-90717: "Invalid App Store Icon. The App Store Icon in the asset catalog in 'YourApp.app' can't be transparent nor contain an alpha channel."
我提交了一份不透明的文件。所以在提交到iTunes Connect时错误仍然存在。

I also tried exporting without alpha it did not work for me but I figured it out that why I was getting error. I create an AppIcon using Figma & Sketch, but I tried to make a 2D geometry shape to 3D viewable. So I assume that I can achieve it by using some shadows & the same geometry but with lower alpha-like %70. After that, I got the AppIcon and export it without Alpha ticking but the problem was the main source of the image includes a container with lower alpha-like I did. So I change it to another graphical shape without alpha and it worked.
如果ionic3项目在上传到iTunes Connect时显示此错误，请检查此答案
这是我的项目错误，当我试图诋毁。
最后遵循这个答案，错误解决了。
可供选择:(使用Sierra或High Sierra和Ionic)
复制并粘贴应用商店图标到桌面。 打开映像。单击“文件菜单”->副本。 通过取消Alpha通道来保存它。 用这个图标替换当前的App Store图标。 验证并上传。
