If anybody stumbles across this from Google, I found that the simplest thing to do was:

Have devs install rbenv on their machines, and add ~/.rbenv/shims to the PATH in the XCode build script like:

export PATH=~/.rbenv/shims:$PATH
# Exec rest of your script
# ...

	extension UIColor {
	convenience init? (fromHex hex: String) {
	let hexPattern = try! NSRegularExpression(pattern: "^[0-9a-fA-F]{6}$",
	options: [.anchorsMatchLines])
	let range = NSRange(location: 0, length: hex.characters.count)

	guard hexPattern.matches(in: hex,
	options: [],
	range: range).count == 1
	else { return nil }

	override func viewDidLoad() {
	super.viewDidLoad()
	let slider = UISlider(frame:CGRectMake(70, 550, 280, 20))
	slider.minimumValue = 0
	slider.maximumValue = 100
	slider.continuous = true
	slider.tintColor = UIColor.redColor()
	slider.value = 50
	slider.addTarget(self, action: #selector(ViewController.sliderValueDidChange(_:)), forControlEvents: .ValueChanged)
	self.view.addSubview(slider)

	# first run brew install ffmpeg && brew install imagemagick
	# next, add lines 6 - 9 into your .zshrc or .bashrc file, depending on your shell you use ( zsh or bash )
	# restart your terminal!
	# then call like "movtogif in.mov out.gif"

	movtogif(){
	ffmpeg -i "$1" -vf scale=800:-1 -r 10 -f image2pipe -vcodec ppm - \|\
	convert -delay 5 -layers Optimize -loop 0 - "$2"
	}
