ios app crashes in xcode

Question

What does this mean when I tried to build:

clang: error: no such file or directory: '/Users/chris/Developer/Happy People - Parse/User.m'
clang: error: no input files
Command /Applications/Xcode5-DP5.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

Answer 1

很可能是您从磁盘上删除了文件，但没有从XCode的项目中将其删除。

Answer 2

Xcode is not able to locate the User.m file. It might be removed or relocated.

Answer 3

Probably the file user.m is appearing in red color(link is missing), just delete it and add it again. If it is not in red color just remove the reference(while deleting remove reference only) and add it again
