When ideviceinstaller is being installed using brew during appium dependency installation, the following error is received:
+ brew install ideviceinstaller ==> Downloading https://homebrew.bintray.com/bottles/libplist-2.2.0.catalina.bottle.tar.gz ==> Downloading https://homebrew.bintray.com/bottles/libusb-1.0.24.catalina.bottle.tar.gz curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to homebrew.bintray.com:443 Error: Failed to download resource "libusb" Download failed: https://homebrew.bintray.com/bottles/libusb-1.0.24.catalina.bottle.tar.gz
Adding brew install --HEAD libimobiledevice before brew install ideviceinstaller prevents the problem from occurring.
