error: unable to load standard library for target 'arm64-apple-ios10.0-simulator'?

Question

I updated my Xcode but not able to build. It's failing with:

<unknown>:0: error: unable to load standard library for target 'arm64-apple-ios10.0-simulator'

Merge Script:

 # 1
# Set bash script to exit immediately if any commands fail.
set -e

# 2
# Setup some constants for use later on.
FRAMEWORK_NAME="SDK"
OUTPUT_PATH="${SRCROOT}"

# 3
# If remnants from a previous build exist, delete them.
if [ -d "${SRCROOT}/build" ]; then
rm -rf "${SRCROOT}/build"
fi

# 4
# Build the framework for device and for simulator (using
# all needed architectures).
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch 
arm64 -arch armv7 -arch armv7s only_active_arch=no defines_module=yes - 
sdk "iphoneos"
xcodebuild -target "${FRAMEWORK_NAME}" -configuration Release -arch 
x86_64 -arch i386 only_active_arch=no defines_module=yes -sdk 
"iphonesimulator"

Answer 1

Actually solved this by selecting Generic iOS Device when building instead of a simulator device.

Edit: I should mention, in Xcode 10.

Edit 2: I'll post my universal framework script

set -e
