Modified arguments passed to xcodebuild when building iOS apps.

[freakboy3742]

Xcode 16 has introduced a warning about the -destination argument passed to xcodebuild when building iOS apps:

--- xcodebuild: WARNING: Ignoring provided run destination because no scheme was passed.

This warning correctly identifies that the -destination argument is redundant when performing a build, as there is no run destination. This PR removes the argument, preventing the warning.
