Using homebrew installed SDL2 with Xcode

1. Install installed homebrew from https://brew.sh

2. Type in terminal brew install sdl2

3. Then show the path of framework (in xCode select project file >> build settings >> header search paths) and using cmd+shift+g type /usr/local/include

4. In 'General' 'Frameworks & Libraries' put libSDL2-2.0.0.dylib (its here /usr/local/Cellar/sdl2/2.0.14_1/lib)

5. And most important check 'Disable Library Validations' in 'Signing & Capabilities'

After these steps code started to work for me.

To be able to use SDL2 on Xcode you must set two things (which are required for SDL in general):

• where to find header files (so that Clang can compile with -Iheader/path)
• where to find the .dylib to link it to the project (since with brew you don't have a real .framework)

To know the correct paths you should invoke sdl2-config --cflags and sdl2-config --libs. On my system these produce:

:~jack$ /usr/local/bin/sdl2-config --cflags
-I/usr/local/include/SDL2 -I/usr/X11R6/include -D_THREAD_SAFE

:~jack$ /usr/local/bin/sdl2-config --libs
-L/usr/local/lib -lSDL2

Now just paste the first one into other C flags and the other one into other linker flags field of your project and you are ready to go.

You could set them up in the correct fields, which is Header Search Paths for -I and Library Search Path for -l but the result will be the same.
