反应本机升级相关类型错误

Question

我升级了本机

"react": "16.9.0",
"react-native": "0.61.4",

到

"react": "16.11.0",
"react-native": "0.62.2",

我所做的一切都会对本机升级帮助程序文档做出反应

https://react-native-community.github.io/upgrade-helper/?from=0.61.4&to=0.62.2

但是我遇到了这些错误

"associated type descriptor for Swift.ExpressibleByFloatLiteral.FloatLiteralType", referenced from:

"associated type descriptor for Swift.ExpressibleByIntegerLiteral.IntegerLiteralType", referenced from:

"value witness table for Builtin.Int32", referenced from:

Answer 1

升级到本机0.63.3后出现相同的错误。

这的根本原因是我的项目中只有Objective-C文件。

解决方案是在xcode中的项目下添加一个空的swift文件，所有链接错误都将得到解决。

File -> New -> File
