Extremely Slow compile Times on XCode 8.2.1 and swift 3.0.2

[4rianton]

I did a profiling on my build times since lately my builds were taking copious amounts of time.

I followed the instructions here: http://irace.me/swift-profiling

I would like to report that removing these lines:

        chart = PieChartView(autoLayout: true)
        chart.usePercentValuesEnabled = true
        chart.rotationWithTwoFingers = true
        chart.holeRadiusPercent = 0.7
        chart.setExtraOffsets(left: 50, top: 0, right: 50, bottom: 0)
        chart.descriptionText = ""
        chart.legend.enabled = false
        chart.highlightPerTapEnabled = false
        addSubview(chart)
        
        let separator = LineView(autoLayout: true)
        addSubview(separator)
        
        addContractButton = Button(autoLayout: true)
        addContractButton.setTitle(NSLocalizedString("", comment: "").uppercased(), for: UIControlState())
        addContractButton.backgroundColor = UIColor.blueVXColor()
        addSubview(addContractButton)

using the report from the profiling:

52344.7ms	/Users/x/Documents/Development/x-iOS/x/ContractsStatsView.swift:37:10	@objc func setupUI()
47448.6ms	/Users/x/Documents/Development/x-iOS/x/ContractsStatsView.swift:37:10	@objc func setupUI()

1714.9ms	/Users/x/Documents/Development/x-iOS/x/WelcomeView2.swift:35:10	@objc func setupUI()

has cut 52 seconds from my build time. Is this a known issue? Is there a way to fix this? I am building all the views programmatically if that matters.

Well those come from your app not Charts. I just did the same thing with the library code and the longest file to compile is 278.0ms. I believe the problem is on your end.
