iOS Example Project Running Notes

Issue 1: iOS boost Dependency Installation Error

When installing iOS dependencies, you may encounter the following error:

Root Cause

This error occurs because CocoaPods performs SHA-256 verification on "downloaded local source code archives", and the result doesn't match the value declared in the podspec file, causing the installation to terminate directly.

Solution

1. Locate the podspec file

   From the log information, you can find the location of the boost podspec file:

   example/node_modules/react-native/third-party-podspecs/boost.podspec
   

   

2. View current configuration

   The content of this podspec file is as follows:

   

3. Modify the download link

   Refer to Error installing boost: Verification checksum was incorrect, expected to modify the link in the podspec file.

   Original link:

   https://boostorg.jfrog.io/artifactory/main/release/1.76.0/source/boost_1_76_0.tar.bz2

   Change to:

   https://archives.boost.io/release/1.76.0/source/boost_1_76_0.tar.bz2

4. Reinstall dependencies

   After modification, save the file and then go to the example/ios directory to execute:

   pod install

Issue 2: iOS Example Startup Error

When executing yarn example ios from the root directory to run the example project on iOS simulator (or physical device), you may encounter the following error:

Root Cause

From the logs, the following error is found:

Solution

1. Locate the problematic file

   Find the file in example/ios:

   example/ios/Pods/Headers/Public/Flipper/FlipperTransportTypes.h
   

2. Add header file reference

   Add #include <functional> below #include <string>, as shown in the following image:

   

   Reference: FlipperKit 'facebook::flipper::SocketCertificateProvider' (aka 'int') is not a function or function pointer template named 'function' in namespace std

3. Rerun the project

   Then execute from the root directory again:

   yarn example ios

   This will successfully run the example project on iOS simulator (or physical device).
