Try changing DEPLOYMENT_TARGET to "10.0" like the error message suggests.

Try changing DEPLOYMENT_TARGET to "10.0" like the error message suggests.

I tired it somewhere in middle It appears something different again during the installation process when building the ARMv7 library, and a message indicates that a maximum deployment target of 13.0 is required.
