swift 编译打包错误汇总

1.swiftc failed with exit code 1

archive时，将schema设置成release，无法编译通过，报错如下
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swiftc failed with exit code 1

解决方案：将"Optimization Level"设为“None”，设置路径：Target > Build Settings > Swift Compiler > Optimization Level.

2.当项目从xcode beta 1切换beta 5报各种编译错误，可尝试清除~/Library/Developer/Xcode/DerivedData目录下的对应项目

3.在接入Mob短信验证SMS SDK时，第一次编译正常，关掉xcode后再次编译报 /BridingHeader.h:13:9: 'SMS_SDK/SMS_SDK.h' file not found 错误。原因是 FrameWork Search Paths 中SDK路径还有空格导致，追根溯源，是下载下来的SDK zip文件名带空格，mac下解压缩默认就用文件名做目录名，所以也带空格了。

4.升级到xcode7.1后重新编译报 Command failed due to signal: Segmentation fault: 11 错误

解决方案：

@objc protocol ChatInputDelegate:NSObjectProtocol
{
    optional func chatInput(input:ChatInput, frameChange frame:CGRect)

}

delegate?.chatInput?(self, frameChange: targetRect)

改为

@objc protocol ChatInputDelegate:NSObjectProtocol
{
    func chatInput(input:ChatInput, frameChange frame:CGRect)

}

delegate?.chatInput(self, frameChange: targetRect)
