xcode8-beta4

I made a messages extension and when I run it on the iOS simulator everything runs no problem. When I try to run it on my phone, it compiles and says running for about 5 seconds before crashing and giving me a pop down message in Xcode saying Could not attach to pid Here is a screenshot: I am using Xcode 8 beta 4 with iOS 10. Everything runs fine in simulator this is on physical device. I have rebooted and restarted everything. I have even tried on two phones. Anyone know the solution? Thanks Okay this is a tough one. I went searching though the Xcode beta 4 release notes and found the answer

This Swift 3 code worked until XCode 8 beta 3: let calendar = Calendar.current let anchorComponents = calendar.components([Calendar.Unit.day, Calendar.Unit.month, Calendar.Unit.year, Calendar.Unit.hour], from: self) In Xcode 8 beta 4 Calendar.Unit appears to be renamed to Calendar.Component . Now this code let calendar = Calendar.current let anchorComponents = calendar.components([Calendar.Component.day, Calendar.Component.month, Calendar.Component.year, Calendar.Component.hour], from: self) produces the compiler error cannot convert value of type Calendar.Component to NSCalendar.Unit Am I

My code (fragment below) causes the Simulator to Hang. What am I doing wrong? To reproduce the problem, cut and paste into the Simulator. class INK { var test = 1 } var array = [INK!](repeating: nil, count: 1) for idx in 0..<array.count { array[idx] = INK() } var idx2 = 0 for ink_item in array { idx2 += 1 print("idx2=\(idx2)") } Hamish This is a known bug, see SR-1635 . Since an IUO is no longer a distinct type , it shouldn't really be possible to have an array of them in the first place. This is confirmed by the fact that the following code fails to compile: // compiler error: Implicitly

Xcode 8 beta 4 no longer recognizes Foundation class AttributedString . I've reproduced it in this simple playground example: //: Playground - noun: a place where people can play import Foundation let attrStr1 = NSAttributedString() let attrStr2 = AttributedString() // Use of undeclared type 'AttributedString' Since AttributedString was available in older Xcode 8 Swift 3 betas, I imagine this is a Foundation bug that needs to be fixed, rather than some source code error in Playground? Although undocumented in the Xcode release notes, a version 2 update to Swift evolution proposal SE-0086 Drop

so I recently just updated to Xcode 8 and I just got this error for the following code. The error is that the method doesn't override any method from it's superclasses. override func preferredStatusBarStyle() -> UIStatusBarStyle { return UIStatusBarStyle.lightContent } I would really appreciate help, thanks! In iOS 10, preferredStatusBarStyle is a property, not a method. So instead of overriding it with a func declaration as you've done, you override the getter with a var declaration: override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent } The Swift compiler's error

I have been only recently working with Xcode 8 beta 4 but it has been working fine up until now. The list of simulators is not showing for any of my projects. I already tried Creating a new Scheme and it did not work. How do I fix this? Deleting derived data and restarting Xcode worked in my case. rm -rf ~/Library/Developer/Xcode/DerivedData/* Ensure your Deployment Target version in Build Settings is also set to the desired version (and that you have that version of the respective simulator installed). In the below example, if that were set to 10.3 and I didn't have an iOS 10.3 simulator
