报错原因：
Multiple commands produce '/Users/wenjing/Library/Developer/Xcode/DerivedData/NIM-hkcrzzsoipvdvuddllwgxqpejhen/Build/Products/Debug-iphoneos':
- CreateBuildDirectory /Users/wenjing/Library/Developer/Xcode/DerivedData/NIM-hkcrzzsoipvdvuddllwgxqpejhen/Build/Products/Debug-iphoneos
- That command depends on command in Target 'NIMKit' (project 'NIMKit'): script phase “[CP] Copy Pods Resources”
造成原因：
构建选项【New Build System】严格检查引起的。
Xcode13更改后
解决：
方法一：将Build System选项从【New Build System】，恢复为【Legacy Build System】即可，但Xcode13 又会引起其它问题。不推荐
方法二：
在target -> Build phase > Copy Bundle Resource移除掉
