How can I contribute?

Thanks for asking! We love pull requests from everyone. Depending on what you want to do, you can help us improve Linphone in various ways:

Help on translations

We no longer use transifex for the translation process, instead we have deployed our own instance of Weblate.

Due to the full app rewrite we can't re-use previous translations, so we'll be very happy if you want to contribute.

Report bugs and submit patchs

If you want to dig through Linphone code or report a bug, please read CONTRIBUTING.md first. You should also read this README entirely ;-).

Building the application

What's new

With Linphone 6.0, we are switching to Swift Package Manager.
By default, the app uses a remote SPM repository: https://gitlab.linphone.org/BC/public/linphone-sdk-swift-ios.git
However, if you wish to use a locally built SDK, please refer to the section “Using a local Linphone SDK” below for instructions.

Building the app

Open linphone.xcodeproj with Xcode to build and run the app.
The remote SPM is already configured in the app.

Using a remote Linphone SDK (Optional)

If you want to switch the dependencies back to the remote SPM, here’s how to proceed:

• Go to the Package Dependencies section of your project.

• In the top-right corner of the screen, enter the following URI: https://gitlab.linphone.org/BC/public/linphone-sdk-swift-ios.git
• Change the Dependency Rule to Branch, and enter the keyword stable.
• Click Add Package.

• A new page will open to let you add targets to the library. Normally, this is not necessary, as the dependencies on Linphone and msgNotificationService should already be present.
• Click Add Package.

• Make sure the library appears in the Frameworks, Libraries, and Embedded Content section of all targets that need it.

• Add it manually if needed.

Using a local linphone SDK (Optional)

• Clone the linphone-sdk repository from our GitLab:

git clone git@gitlab.linphone.org:BC/public/linphone-sdk.git
git submodule update --init --recursive

• Build the SDK:

cmake --preset=ios-sdk -G Ninja -B spm-ios && cmake --build spm-ios

• Go to the Package Dependencies section of your project (remove the remote linphonesw SPM from the package dependencies if necessary)

• Click on Add Local.

• Follow your path: yourSdkPath/linphone-sdk/spm-ios/linphone-sdk-swift-ios

• A new page will open to let you add targets to the library. Normally, this is not necessary, as the dependencies on Linphone and msgNotificationService should already be present.
• Click Add Package.

• Make sure the library appears in the Frameworks, Libraries, and Embedded Content section of all targets that need it.

• Add it manually if needed.
