Can anyone help and provide guidance on how to add debug buttons to the Touch Bar?According to the Help text, it should be possible to customize teh Touch Bar, but I am unable to get this to work at all. The options shown when I View -> Customize Touch Bar are very limited, and do not give me options to add Debug related buttons.Thanks.CUSTOMIZE XCODECustomize the Touch Bar controlsCustomize the Touch Bar controls for the source editor, Playground editor, Interface Builder, view debugger, and memory graph debugger.Open the desired editor or debugger.Choose View > Customize Touch Bar.Add, rearrange, or remove a button in the Touch Bar.Add a button: Drag a button from the screen to the Touch Bar; buttons in the Touch Bar jiggle slightly.Rearrange a button: On the Touch Bar, drag a button do the desired location.Remove a button: Drag a button from the Touch Bar to the screen.On the Touch Bar, tap Done.

I'm integrating a 3rd party library in my project. After updating to the latest version and switching from regular frameworks to XCframework I've started seeing this issue:Whenever I'm trying to inspect an object from the 3rd party library via LLDB console, e.g.po <object.property>i'm getting this error:error: Couldn't lookup symbols: dispatch thunk of <...>At the same time I can inspect the object in the Variables ViewAny idea if this is an integration or framework distribution issue ?

Recently, I have upgraded my Xcode version from 9.2 to 11.3.1. My project, which was written in Swift 4, worked completely fine in 9.2. However, when trying to run it in 11.3.1, I have been experiencing random "EXC_BAD_ACCESS" crashes in areas of code that previously worked just fine. Now, the areas of code that are being affected are essentially identical to previous sections of the code, and when stepping through the code, every condition appears to be working just fine (nothing is nil or anything like that). I enabled zombie objects to check for deallocation, but I found nothing. Is there any particular issue with regards to upgrading to Xcode 11 I should be aware of, and any ideas of what might be causing this?

I've got a macOS app with a "Helper" (LoginItem) app that I'd like to attach the debugger to in order to debug the communication between the two.I realize hardening a target makes it impossible to attach the Xcode debugger to it, however I've created a separate entitlements file for Debug mode, turned "Enable Hardening" OFF for both Debug targets and have also added a "com.apple.security.get-task-allow" set to "YES" in the entitlement files for both debug targets. Still, I see this:macOSTaskPolicy: (com.apple.debugserver) may not get the taskport of (com.b) (pid: 4144): (com.b) is hardened, (com.b) doesn't have get-task-allow, (com.apple.debugserver) is a declared debuggerI'm unable to debug the helper and it's frustrating. How can I disable SIIP or whatever it takes to get this to work?

My macOS app compiles and runs fine, but since switching to Xcode 11, I can no longer debug from breakpoints. The debugger always crashes with a bunch of messages like this:warning: Swift error in scratch context: /foobar/Foo-Bridging-Header.h:14:9: note: in file included from /foobar/Foo-Bridging-Header.h:14: #import "TPPreciseTimer.h" ^ error: /foobar/Timer/TPPreciseTimer.h:9:9: error: 'Foundation/Foundation.h' file not found #import <Foundation/Foundation.h> ^ /foobar/Timer/TPPreciseTimer.h:9:9: note: did not find header 'Foundation.h' in framework 'Foundation' (loaded from '/System/Library/Frameworks') #import <Foundation/Foundation.h> ^ error: failed to import bridging header '/foobar/Foo-Bridging-Header.h' . Shared Swift state for Foo has developed fatal errors and is being discarded. REPL definitions and persistent names/types will be lost. Message from debugger: The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log.Anyone know a workaround for something like this?My coworkers still on Xcode 10.3 are not having this issue with the same codebase.

When I attempt to launch an app from Xcode 11 (gm seed 2) to my attached iPhone running iOS 13 the I see the app launch with a white screen but then the iOS process hangs for about *60 seconds* before the app finishes launching. If I un-check "debug executable" on the target then this behavior does not happen. If I launch the app on the phone directly (without xcode) it launches normally. If I launch the app on the phone and attempt to attach the debugger from xcode I get the same (one minute) hang.This only happens on one of my machines even though both are using the same setup (only diff is that one is a laptop and one is a desktop). So I am assuming something is wrong or corrupted with the "debug support" that was installed on first connect to the new xcode... But I can find no reference to how to re-init that. I have tried the "unpair phone" option in devices in xcode but it does nothing. I don't see anything in settings related to developer profiles or debug symbols.Anything I can do to reset the phone with respect to debgging support / symbols installed by xcode? Any other thoughts?thanks,Pat

Xcode debug my app, I find some thread no stack, only 0x00000000 (but not crash).Stack info:error: memory read failed for 0x0I think stack overflow, so I try use tool "Address Sanitizer", but not found too.Why is this happening, xcode no stack?Screenshot url:https://i.stack.imgur.com/N0wGW.png

Running fine in simulator but crashes in device.No crash logs recorded.In line error shown after launching the app Thread 1: EXC_BAD_ACCESS (code=1, address=0x81b4288100000002).No main or didFinishLaunchingWithOptions is called yet.Tried re-installing the application.

Why is the line number 0 for my source code in symbolicated crash log?At line 4 in Thread 0, the line number is 0 for (MyCodeModule.swift:0). Why is that? Is there a way to get more details about where it crashed?This is from a crash log a customer sent. The crash seems to be coming from somewhere in string processing routines.Are Swift line number references only delivered for functions/methods in Swift classes, but not free-standing functions?Also, is there a way to get symbolicated names for the libswiftCore.dylib lines in the crashed thread?Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libswiftCore.dylib 0x0000000104c04324 0x104948000 + 2868004 1 libswiftCore.dylib 0x0000000104bcbb6c 0x104948000 + 2636652 2 libswiftCore.dylib 0x00000001049c48fc 0x104948000 + 510204 3 libswiftCore.dylib 0x0000000104bd4f14 0x104948000 + 2674452 4 MyAppName 0x0000000104536e00 specialized MyFunctionOne(_:parameter:) + 339456 (MyCodeModule.swift:0) <-- HERE 5 MyAppName 0x000000010455c3b8 MyController.myMethodTwo(_:parameter:) + 492472 (MyController.swift:1090)Other pertinent lines from crash log:Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000020 VM Region Info: 0x20 is not in any region.

I am trying to establish a remote connection to an iOS 11 device for debugging. Both devices are on the same Wi-Fi network, I'm using Xcode 9 and in Window->Devices and Simulators have checked the "Connect via network" box. I do not get a network icon next to my device, nor do I get any prompt on the device itself.The application if for point of sale and the Wi-Fi firewall has most ports blocked. For example, I know port 22 (ssh) is blocked - the only open port I'm certain of is 8080. I suspect the port used for debugging is blocked. What port(s) are used for debugging? I can request the network guys open a few ports if needed.

I'm working with what appears to be a low-memory crash on an iPhone 4s that isn't mine. I can see JetsamEvent-<date> files being created, but I don't have a good way to get them back to my computer: they do not show up in the Device Logs sheet of Xcode's Devices window, and there's no way to manipulate them on the phone (under Settings > Diagnostics & Usage > Diagnostics & Usage Data) other than to manually select and copy all the text, and then mail or iMessage it to mysefl. There has to be a better way, right?Thanks.—Chris

Hello, I am creating an app that needs internet in order to work. So if I try to build it on my test device with the new Network link conditioner and set the 100% loss profile the app won't even build. It gives me the security issue message. Even though my profile self is trusted on my device already. How am I able to test if the app won't build without internet connection?
