TVOS with Xcode generator error

[sy6sy2]

Hi,

Your example with the TVOS platform and the Xcode generator seems to produces an error :-/

Command to reproduce:

cd example/example-lib
mkdir build
cd build
cmake .. -G Xcode -DCMAKE_TOOLCHAIN_FILE=../../ios.toolchain.cmake -DIOS_PLATFORM=TVOS

Stdout:

I will take a look at this today along with some other issues. Unclear to me right now why it sets both iphone an tvos flags together..

Thank you!

Fixed in v3.0.0 🚀
