Xcode 8 beta 6: main.swift won't compile

Question

We have a custom UIApplication object, so our main.swift was

import Foundation

import UIKit



UIApplicationMain(Process.argc, Process.unsafeArgv, NSStringFromClass(MobileUIApplication), NSStringFromClass(AppDelegate))

and that didn't work in Xcode 8 beta 5 so we used this

//TODO Swift 3 workaround? https://forums.developer.apple.com/thread/46405

UIApplicationMain( Process.argc, UnsafeMutablePointer<UnsafeMutablePointer<CChar>>(Process.unsafeArgv), nil, NSStringFromClass(AppDelegate.self))

On Xcode 8 beta 6 we get Use of unresolved identifier 'Process'

What do we need to do in Xcode 8 beta 6/Swift 3 to define the UIApplicationMain?

Answer 1

I write it this way:

UIApplicationMain(
    CommandLine.argc,
    UnsafeMutableRawPointer(CommandLine.unsafeArgv)
        .bindMemory(
            to: UnsafeMutablePointer<Int8>.self,
            capacity: Int(CommandLine.argc)),
    nil,
    NSStringFromClass(AppDelegate.self)
)

To change the UIApplication class, substitute NSStringFromClass(MobileUIApplication.self) for nil in that formulation.
