@react-native-community/geolocation 导致 ios 编译错误

Question

我的系统：

MacOS: Big Sur
XCode: Version 12.5.1 (12E507)
iOS Simulator: iPhone 8 (iOS 14.5)
Node: v16.10.0

我创建了新的 React Native 项目：

npx react-native@latest init MyFreshProject

创建成功。

npm run ios

在iOS模拟器上运行成功。

然后我安装了

@react-native-community/geolocation

（^3.0.6）。我将以下代码添加到

Info.plist

中：

<key>NSLocationWhenInUseUsageDescription</key>
<string></string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string></string>

并在

App.tsx

中添加了以下代码：

import Geolocation from '@react-native-community/geolocation';
...
...
useEffect(() => {
  Geolocation.getCurrentPosition(info => console.log(info));
}, []);

这些更改之后，我再次运行

npm run ios

并构建失败并输出：

...
...
...
/Users/aberikashvili/Documents/.../MyFreshProject/node_modules/@react-native-community/geolocation/ios/RNCGeolocation.mm:393:23: error: property 'sourceInformation' not found on object of type 'CLLocation *'
mocked = location.sourceInformation.isSimulatedBySoftware;
                  ^
1 error generated.


** BUILD FAILED **


The following build commands failed:
CompileC /Users/aberikashvili/Library/Developer/Xcode/DerivedData/MyFreshProject-cviktleltpvwpcdkzpdqowhphiwn/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/react-native-geolocation.build/Objects-normal/x86_64/RNCGeolocation.o /Users/aberikashvili/Documents/.../MyFreshProject/node_modules/@react-native-community/geolocation/ios/RNCGeolocation.mm normal x86_64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

我尝试注释掉

Geolocation

中的

App.tsx

用法，但构建仍然失败。

有什么想法吗？

附注这个问题已经折磨我好几天了

Answer 1

实际问题是，

CLLocation Source Information

支持iOS 15+，而iOS 15本身需要XCode 13+（我的是12）。

所以，解决方案是将 MacOS 从

Big Sur

更新到

Ventura

，安装最新的 XCode 就可以了
