# Usage:
# cmake .. -DDEPS_PATH=/path/to/dependencies -DIOS_ASSETS=/path/to/generated/assets -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchain-ios-xcode.cmake -G Xcode
# Need to use ../android/generate_assets.sh for assets first
# In Xcode you need to choose Product -> Scheme -> supertuxkart
# And then Signing & Capabilities choose a suitable team
# You may need to use another bundle identifier as the current one is already used by STK team
# You can also use -DCMAKE_XCODE_ATTRIBUTE_DEVELOPMENT_TEAM=xxxxxxxxxx to specify team

# Increase every upload to App store
