这是因为资产目录中的JPG图像，所以我直接在项目中导入jpg图像，现在它工作
资产中的Xcode V7b6和JPG图像也有同样的问题。 奇怪的是，这是为一些JPG而不是其他人。
然后，我看了JPG和他们的颜色configuration文件，exif数据和其他meta的东西，确实删除这些数据（通过GraphicConverter）解决了我们和Xcode现在build立罚款。
图像资产中的PDF文件将导致此错误。 我使用@ 1x @ 2x @ 3x图像的PNG文件和Xcode工作正常。
有时你应该取消select“alpha”选项来导出你的PNG图像到Xcode。 这解决了我的问题。
打开“预览”应用程序 – 文件 – 导出 – 取消选中“alpha”选项，然后在Xcode项目中replace旧图像。
我也遇到了这个问题，并用普通的.JPG文件replace了XC资产。 为我解决了。
但是，我刚刚安装了Xcode 7的GM种子发行版，并使用XC资产目录进行构build，不再遇到错误。 所以似乎已经修复了。
对于Xcode的所有testing版本，您应该转到“首选项” – >“位置” ，并确保命令行工具指向正确的版本 ，派生数据和归档指向稳定Xcode的另一个文件夹
有这个actool错误在Xcode 8 Beta 6build立一个简单的贴纸包。
似乎是animation贴纸的一个已知的错误 ，应尽快解决。
这个错误发生在我身上，因为图像名称包含一些不受支持的字符（它被Xcode保存为c71a25e%2FÍcone-XPTO Imagem - 120x120.png ，即使放在.xcassets中也是如此）。
更改图像名称解决了这个错误对我来说。
