Building for iOS can only be done on a Mac.

Install Xcode - https://developer.apple.com/xcode/

Before you start this process, open Xcode, go to settings, accounts, and sign in with your Apple ID. If you are a Mozilla developer, this is an Apple ID associated with your LDAP account.

$ conda env create -f env.yml -n vpn
$ conda activate vpn

See here for conda environment instructions.

Install extra conda packages

$ conda activate vpn
$ ./scripts/macos/conda_install_extras.sh

$ conda activate vpn
$ ./scripts/macos/conda_setup_qt.sh

Complete the steps in macOS.md#configure-xcode-build-environment.

Configure, using the qt-cmake

qt-cmake -S . -B build-ios

This will generate an Xcode project file at build-ios/Mozilla VPN.xcodeproj which can be opened by Xcode:

open build-ios/Mozilla\ VPN.xcodeproj

Once Xcode has opened the project, select the mozillavpn target and start the build.

Tips:

• If you can't see a simulator target in the Xcode interface, look at Product -> Destination -> Destination Architectures -> Show Both
• Due to lack of low level networking support, it is not possible to turn on the VPN from the iOS simulator in Xcode.
