'iosfwd' file not found #28

We do not support swift projects yet. We are working on it. Look at the issue #13 |

The same, but mine is a Objc project. |

Xcode Version 9.4.1 (9F2000) |

@JiandanDream @iineva I'm seeing this error also. AFAIK, this should work since Cocoapods should be able to compile this objc module to make it usable in a Swift module. Do either of you have a sample project I could look at to try to reproduce? An objc project fails with this error would be best for investigation purposes. |

@noahsark769 You can try this: Test.zip pod update
pod install
# than build project. |

Can confirm that the same error happens for me on @iineva 's test project, which has no Swift (I'm running Xcode Version 9.3 (9E145)). @priteshrnandgaonkar can we reopen this since it's not a Swift specific issue? |

@iineva after trying a few things, I was able to make your project compile by adding the search path
I have to say that I'm not exactly sure what's happening here to fix it, but I tested it twice. Unfortunately, with my project, I still get the same error :( |

It looks like facebook/yoga#697, facebook/react-native#17556, facebook/yoga#711 were similar issues that React Native had with Swift projects. The fix there seems to have been to specify |

This ended up being a search path issue. See explanation at #13 |
Summary: This PR adds support for using SonarKit clients in Swift apps. Fixes #13, fixes #87 1. Swift can't import Obj-C modules which have C++ headers. For this reason, we use SonarKit as an Obj-C++ wrapper around Sonar, which is written in C++. Due to search path misconfiguration, trying to import SonarKit into a Swift project would import `xplat/Sonar/SonarPlugin.h` instead of `iOS/SonarKit/SonarPlugin.h`, which caused `file not found` errors for C++ stdlib imports like #28 because new projects don't have their search paths set up correctly. 2. The network and layout plugins have C++ definitions (struct methods, classes) in some of their headers. This causes the compiler to get confused for Swift projects, because it only supports importing Objective-C files in umbrella headers, meaning that the `SonarKit` won't build. 1. I updated the `HEADER_SEARCH_PATHS` of SonarKit.podspec's build configuration to include `${PODS_ROOT}/Headers/Private/SonarKit/**` first, which alleviates the search path issue. The Obj-C `Sample` project seems to have worked around this by including a hardcoded `${PODS_ROOT}/SonarKit/**` search path in the pbxproj, which is why Sample works but new projects (like those referenced in #28) don't. I removed this since it's no longer necessary. 2. I added a `SampleSwift` app to demonstrate using Sonar with a Swift project. 3. Because the Podfiles for `Sample` and `SampleSwift` referenced podspecs using `:podspec` instead of a concrete version, Cocoapods wouldn't copy local header files (instead, it downloads them from the source). To enable local development of these sample apps using `:path`, I added a symlink to SonarKit.podspec in the root of the directory. 4. I changed SonarKit.podspec to use a tag-based `source`, since v0.0.1 pulls from the master branch of this repo. The layout and network plugins still don't work with Swift - in order to fix this, we'll need to work on extracting the C++ out of their headers and writing Obj-C++ wrappers for them. I decided to push this off to a later PR since this one is quite large already. This means that we need to be able to `import SonarKit` without importing all the network/layout plugin headers. In order to make this work, I made "SonarKit/Core" the spec's `default_subspecs`. priteshrnandgaonkar, let me know if you have any thoughts on this implementation. You can verify that the SampleSwift app works by checking out this branch, `pod install`ing in the SampleSwift directory, and building it :)  Pull Request resolved: #106 Reviewed By: jknoxville Differential Revision: D8890010 Pulled By: priteshrnandgaonkar fbshipit-source-id: 449305bcc5cbeb5787c23f51b1ecb80a5cbdad32
