For iOS >= 9.0 instruments without delay (iwd) does not work by passing binaries through the command line (appium does this under the hood for xcode < 7). See iwd
For enabling iwd for xcode >= 7,
- Checkout appium-instruments
- Run
xcode-iwd.sh
present in<appium-instruments>/bin/
sh <appium-instruments>/bin/xcode-iwd.sh <path to xcode> <path to appium-instruments>
eg. sh ./bin/xcode-iwd.sh /Applications/Xcode.app /Users/xyz/appium-instruments/
Note: iwd with xcode7 will only work for iOS >= 9.0, you can switch to older xcode for iOS < 9.0
