Tip: The SFML example comes with a resourcePath() function which you have to put before the paths to load resources. You can use tgui::setResourcePath(resourcePath()) at the beginning of your program so that everything tgui loads starts with that folder.

Getting TGUI

If you use homebrew then you can install the unofficial TGUI formula by executing:

brew install tgui

Alternatively, you can download the source code from the download page and follow the ‘building with CMake’ tutorial for a guide on how to build TGUI.
After you ran make like explained in the tutorial, you should call sudo make install to install the libraries which you just built.

Instructions are provided below for using either a dylib or framework library. When TGUI is installed with homebrew, you will have dylib files.

Using TGUI (dylib)

Step 1: Create a macOS Command Line project in Xcode and select C++ from the “Language” dropdown menu when prompted to “choose options for your new project.”
XCode Choose project template

Step 2a: Navigate to Targets -> General -> Frameworks and Libraries. Select the “+” icon to add the TGUI and SFML dylibs to the project.
XCode Where to add library

Step 2b: Select “Add Files” from the “Add Other…” dropdown menu. Navigate to the TGUI and SFML dylib locations and include their respective libraries. If you installed using homebrew, this location should be /usr/local/Cellar. If you installed using CMake, this location is the “lib” folder in your build location.
XCode Add library

Step 3: Navigate to Targets -> Signing & Capabilities, and select the “Disable Library Validation” option from the “Hardened Runtime” dropdown.
XCode Disable library validation

Step 4: Navigate to Targets -> Build Phases. Drag “Embed Libraries” to a location before “Compile Sources.”
XCode Build phases order

Step 5: Navigate to Project -> Build Settings -> Search Paths -> Header Search Paths. Double click the blank space next to “Header Search Paths,” select the “+” icon, then enter the paths to the library headers. If you installed with homebrew, this location should be /usr/local/include. Otherwise, the “include” folders will be located in your initial TGUI and SFML download packages.
XCode Header search paths

You should now be able to use TGUI in Xcode.

Using TGUI (framework)

Frameworks no longer worked when last tested. Unless you have experience with macOS it is recommended to use dylib files for now.

All you need to do to use it is drag the TGUI framework into your project. You might also need to copy the framework to /Library/Frameworks.
XCode drag framework

A screen like below will appear where you normally don’t need to change anything, just hit “Finish”. The “Copy items if needed” can remain unchecked, but it doesn’t matter if it is checked.
