iOS Trying to side load Snap+ and keep getting an Xcode error message

[HIGHV0LTAGE]

I've tried to get Snap+ to install on both my iPad Air Wi-Fi iOS 9.3.2 and iPhone 6s Plus iOS 9.3.2/ iOS 10 and keep getting the error '/Users/HIGHV0LTAGE/Desktop/ppsideloader-bmgoaguashsxqacsttmkjzqmnklu/Build/Intermediates/ppsideloader.build/Debug-iphoneos/ppsideloader.build/Script-473D787B1CBAEAA600BA76CD.sh: line 2: /Volumes/HDD/Snap+/ppsideloader-master/script/modify_app: Permission denied' Anyway around this?
