【未解决】Xcode换9.2后代码编译报错:Module compiled with Swift 4.0 cannot be imported in Swift 3.2.3

Xcode crifan 325浏览 0评论

在本身已有:

Version 9.1 beta (9B37)

的情况下,下载了最新的

Xcode 9.2 beta

版后去编译项目,结果出错:

Module compiled with Swift 4.0 cannot be imported in Swift 3.2.3: …/Carthage/Build/iOS/Cartography.framework/Modules/Cartography.swiftmodule/x86_64.swiftmodule

很明显,又是库的版本需要重新编译

那么去参考之前的

【已解决】Xcode9中项目编译出错:Module compiled with Swift 3.1 cannot be imported in Swift 3.2.1

再去试试:

➜  SRT git:(master) ✗ rm -rf ~/Library/Caches/org.carthage.CarthageKit/DerivedData

➜  SRT git:(master) ✗ carthage update –platform iOS –no-use-binaries

Please update to the latest Carthage version: 0.26.2. You currently are on 0.24.0

*** Cloning Cartography

所以先去升级carthage:

【已解决】brew upgrade carthage出错:Error carthage 0.25.0 already installed

然后再去:

carthage update –platform iOS –no-use-binaries

不过突然想到,或许最后也是不行,或许是会由于两个Xcode的版本同存,导致当前的swift的编译器还是3.2.3的?

这个是之前的9.1的Xcode

这个是9.2 beta:

所以还是要等最后看看结果如何。

然后编译等待了1个小时左右,才编译到Realm,还是没有编译完毕,而且CPU始终是100%,电脑卡死。所以干脆中断:

重新开始试试。

最终经历了:大概2个小时,才完整的更新一遍:

然后就再去试试新版的Xcode 9.2中是否可以正常编译

结果还是不行。

TODO:

后续再去想办法看看,Xcode 9.2中如何指定编译器为swift 3.2

目前简单去看了看Xcode 9.2中的配置中,是找不到相关的编译器指定为swift 3.2.3的

并且,项目配置中,本身已经选择了Swift的编译器版本是3.2.3,而不是4.0.1的,

但是不知道为何Xcode 9.2编译时,却内部还是默认用Swift 4去编译?
