“DTiPhoneSimulatorErrorDomain Code 2”

Hi, all, I recently bought an iMac 5K(Late 2015 model) with thunderbolt 2 ports. I was wondering if the eGPU support in high sierra would work on my Mac through a thunderbolt 3 to thunderbolt 2 adapter.

Hi there!I am a novice to Swift and Xcode, but know C++.I tried to mimick the code in a Stanford University course for iOS 8 App development (2014-15) using Xcode 7 and swift 2 for the calculator example.In his lecture 2 video on https://www.youtube.com/watch?v=QLJtT7eSykg,the lecturer suggested over loading a function like this (and I think they were using Xcode 6 and an earlier Swift standard):func performOperation(operation: (Double, Double) -> Double) { if operandStack.count >= 2 { displayValue = operation(operandStack.removeLast(), operandStack.removeLast()) enter() } } func performOperation(operation: Double -> Double) { //////////////////////////////// if operandStack.count >= 1 { displayValue = operation(operandStack.removeLast()) enter() } }However, the compiler seems to have problem with this overloading attempt, and the error is:/Users/.../Calculator/ViewController.swift:50:10: Method 'performOperation' with Objective-C selector 'performOperation:' co

Is it possible to use/draw a SwiftUI view in TextKit 2? The NSTextLayoutManagerDelegate seems to be built around returning a NSTextLayoutFragment. Since NSTextLayoutFragment is a class, I can't subclass it and use SwiftUI. I'd love to create my views using SwiftUI, since it's a lot faster than figuring out CGPaths, pixel perfect anti-aliasing, etc. Thanks!

OR - how can i reinstall the beta 2?

I'm trying to read a file which exist with the below code in Swift 2. It seems to be failing. Appreciate any inputs:let someText = NSString(string:some text)let destinationPath = /users/johnt/myFile.txtvar filemgr = NSFileManager.defaultManager()if filemgr.fileExistsAtPath(destinationPath) { print(File exists) do { let readFile = try String(contentsOfFile: destinationPath, encoding: NSUTF8StringEncoding) // Throws this error// How do I read the file contents from here? print((readFile)) } catch let error as NSError { print(Error: (error.domain)) }} else { print(File does not exist) do { try someText.writeToFile(destinationPath, atomically: true, encoding: NSUTF8StringEncoding) } catch let error as NSError { print(Error: (error.domain)) }}

I have just begun programming Swift, and am a novice, so please bear with me.I would like a basic understanding of how to do the following:Create a two dimensional array where each cell represents an individualRepresent that array graphically so that every pixel represents the person in that cell and the pixel would be pink if the person is female and blue if the person is maleThank you in advance for any and all help!

I'm learning to develop iOS apps. And I'd like to test it on my iPad Air 2. My Xcode is set up as follows: iOS 13.0 Xcode 12.3 Swift 5.3 My iPad is on iOS Version 14.3. I had my iPad Air 2 set up before, but its simulator disappeared when I upgraded the Xcode version. How do I set up Xcode so I can simulate/run apps on an iPad Air 2? Thank you very much in advance.

I wanted to know how would I connect two apps to each other. I am making an app similiar to Uber. An example of what I need help with is in Uber when someone requests a ride that person can see who their driver is and the drivers info on the customer app, and the driver gets the passengers info in the Uber employee app. Even if one person is using an iPhone and the other is using Android.One app is for customers and the other is for employees.

Hi, any idea when beta 2 comes out?
