[![enter image description here][1]][1]I Tried all possible setting manipulation of xcode, even i cleaned xcode app from my mac and then reinstalled too, but still no luck, But Breakpoints works on almost all calsses except some , later on breakpoint navigator i noticed classes on which breakpoint not working are marked RED. I am wondering what is the actual cause ?
Update : After i removed ad added that specific file the red mark are gone, but result is not improved !
I see red text color labels so probably you have deleted files.
If your files exist and you dont see any breakpoint stopped in your class simply it's because your project probably crash before arriving in this class or by-pass it. Check who call DriveCreateAccountVC in your code and put some breakpoints before this class is called in the code, Im pretty sure you find your mistake.
It's a good attitude use the debug console by printing your flow in your code like this line for example: (you can put in viewDidAppear or viewDidLoad)
print("∙ \(NSStringFromClass(self.dynamicType))")
it's a little help but print the class name where are your flow in this moment. You can go also on the debug console and writing for example:
po myStringArray.description
po myStringArray.count
Another useful thing is to add these two options in your editing settings (it's not in defaults settings) : (line numbers and code folding ribbon)
A class becomes Red, when it has lost its path(Xcode can't locate the class)
This may happen because you maybe you copied flies from one project to another or something like that:
There are 2 solutions:
Before anything, locate the files in your Finder
Solution 1) Find the files and put them in your project directory.
Solution 2) Click the file in red in your Project Navigator
Then click on the button (showed in the image link above, to the right of tweetCell.swift)
Once you click it, you will get a chance to locate the file, do it.

Shortly after updating to Xcode 13.2.1 I started seeing some weird behaviour of breakpoints. When I run an app (in a simulator) some of my breakpoints change their look and turn to dotted blue outlined. Xcode does not stop execution at these breakpoints although code has been compiled, loaded and executed. I checked it in Console by adding some prints.
When I hover over breakpoint Xcode shows a message:
Xcode won't pause at this breakpoint because it has not been resolved
Resolving it requires that:
The line at the breakpoint is compiled.
The compiler generates debug information that is not stripped out (check the Build Settings).
The library for the breakpoint is loaded.
All trivial solutions like reloading, reapplying breakpoints have not helped.
Did anybody else see something like this? Is there a way to solve it?
Screenshot for reference:
Ok, so in my particular case rebooting laptop has helped. All breakpoints are now good. But it would still be nice to know the cause of the problem.
Make sure that the file in which you are adding breakpoint is having correct target set in target membership.
Click on .m file in which you want to add breakpoint.
Select the file inspector.
Check if you have selected correct target for that file or not (check below image).
What worked for me, was to select the files, delete them with - Delete>Move To Trash - and then drag the files back from the trash to the project.
In my case the issue was happening, because class was not added to the target, which I was trying to build.
For my case somehow the code path was never invoked and very likely considered as dead code. The same thing applies when not adding the file to the target that you want to debug.
This can be the case or somehow debugger might not be able to resolve your breakpoint. The first thing in this case should be cleaning derived data and any caches.
But instead of recloning your repo you can just delete breakpoint config from the location described in this answer
In Xcode 14 the problem is much more prevalent and "consistent". I figured out one pattern where it always fails and how to mitigate it.
If you have a final class then breakpoints set on or inside a private method will have that issue. If you remove private from the method or final from the class the breakpoints will get resolved properly.
If tried everything and nothing worked I suggest the following:
Reclone your repo
This is what worked for me.
I just passed through this problem and the solution for me was recreating the files.
Note: The ones I was trying to originally breakpoint on were copied from another project. When I created the new files, even though their Identity and Type looked just the same (target membership, encoding, paths), for some reason breakpoints started to work again.
Note 2: When copying and pasting code to your new files (if done manually), migrated breakpoints - created in the older file - will continue to fail. Only the ones created in this new file will work properly.
Hope it helps.
My case
Working on framework development. Framework is injected into the sample app for development/run purpose. Breakpoints inside the framework won't work.
Fix
Just removing xcframework in sample app and replacing with framework.
Reason
xcframework are precompiled outside of the app, so lib isn't compiled when project is built and that's why breakpoints doesn't work.
For me reboot the Xcode, and it works~
When I right click to add a new file (or do File -> New -> File), I don't get a dialogue box asking me which Template I want to use. It just creates a blank file like this:
I tried renaming it to a .swift file and adding in all the necessary code to start off, but two things happen:
First, the autocomplete function is one step behind. So when I've already typed import UIKit and moved on, it starts trying to autocomplete UIKit. And when I've already typed class className: UICollectionViewController {
} and moved on, it starts trying to autcomplete UICollectionViewController
After I manually type in the bare minimum needed to make a swift file into a UICollectionViewController with a colored background, I can't reference it in my other files.
I can only assume this is because of the lack of a template dialogue box, but maybe I'm wrong. Is there any way to toggle this template dialogue box on or off?
This problem is only happening with this particular project since I updated to Xcode 10.1
I can't seem to find anyone else online who's already had this issue. The only similar questions I found online were referring to creating reference folders rather than groups. I didn't find anything regarding the file template dialogue box not showing up.
I fixed this and I'll post the answer in case anyone else comes across this problem.
It was tedious, but I:
Created a new project
Initialized my podfile, added what was in the previous one, and installed it
Opened up the new workspace
Added each file one by one
Maybe there's an easier/quicker way to do it, but after looking through all the settings and not finding anything, I ended up doing this and it worked.
Check that in the left hand pane displaying your project structure you are adding the new file to a folder which comes under your application (identified by a blue Xcode application icon) instead of a general folder as your top level (identified by a blue folder icon). I can't add images yet so please see link.
I'm working in Xcode 9 on a Swift project, and I'm in table flipping mode with this.
Here's my end goal: put my tests next to my logic in a playground so that as I write the logic, I can see the tests pass in close to real time.
I will also accept how to put my tests in a playground by themselves, I just don't want to be running tests on a simulator for every little thing.
My problems in trying to get this to work are many. First and foremost, I can't find a way to add a playground directly to my project/workspace. When I right click on a group in the project navigator and select 'New file...' I get this:
As you can see, no option for playground. Filtering also returns no results. If I press the plus button at the bottom of the project navigator, the same dialog (with no playground option) pops up.
I thought it's in another menu so I went to the File menu, and in "New >" I find an option for creating a playground. I select a blank playground from the chooser, choose where to save it (strange that it wanted to save it under 'Unsaved Xcode Documents') and a basic playground comes up in a new tab. Odd thing I notice, though, is that there's no longer a play button or scheme/simulator selector at the top on this tab.
It now doesn't recognize ANY modules other than Apple provided ones! And sure enough, creating the playground didn't actually add it to my workspace. I guess I have to manually add it to my project. Upon doing so, it will recognize my pods but none of my project files! Any class I try to use gives me an Unrecognized identifier. Trying to import my project doesn't work either, it just gives me a No module.
I tried clearing DerivedData, I tried cleaning, I tried restarting Xcode, I even made sure I had an iPad Pro in the list of simulators (since that seems to matter for some people).
In frustration, I deleted the playground, and resolved just to deal with running my tests constantly. But now, my project has persistent errors! Despite moving the playground to the trash, Swift continues to error saying 'Unresolved identifier' for that playground!
As the excellent Brandon Williams says in his talk at FrenchKit, a playground "does not get access to anything in the application target." Which is ridiculous, but hey, what are you gonna do. So the answer is: there is currently no way to do this the way I asked.
It IS possible, however, to achieve this functionality if your logic is in its own framework/cocoapod. That is, move the logic you want to test out of your app target and into an outside library that your app, subsequently, imports. This will allow your playground to import it as well, and you can test to your heart's content.
After I installed the latest version of xcode i'm having a very annoying issue.
While I'm coding, xcode goes nuts. Without me doing anything weird, just typing code, xcode stop recognizing classes.
For example: I want to add UITableViewDelegate to my class, but it doesnt recognize it. After i type it manually sometimes it recognize it and it is shown in purple, some other time it doesnt. But both times it won't really consider it, so if I try to write down a method of that delegate, it won't show it.
Other times if I try to call a variable of a certain class, while trying to autocompleting it, it shows <>.
Other times if I try to call any class, let's say I try to type var test = UIActionSheet, it just shows a few elements in the autocomplete list (raw types, primitives, the classes of my main project, but it doesn't show the majority of classes).
It's like it's missing the documentation and the link with the main frameworks...
I'm working on a simple tabbed app from yesterday and it's the 3rd time i started all over because of this issue, thinking that starting over would fix the issue, but it's not working.
If i open a different project while the issue is going on, the other project works ( but i recoded all over my app so it's not that one the issue, and i also have the same issue on other project... it just doesn't affect 2 project at the same time )
i tried deleting derived data
i tried restarting both xcode and the comp
What's going on?
Here are two screenshoots where you can see what's happening:
I had the same problem earlier.
Exit Xcode and delete Derived Data folder here ~/Library/Developer/Xcode
Restart Xcode and you should see the autocomplete working again.
You have to learn how to take it apart and put back together.
Either reinstall Xcode, if it doesn't help, create a new project.
Then copy source files one by one and see when it breaks.
Freshly install the XCode IDE version 6.1
Use CMD + F to find all _element.
Check that if you named one variable _element
The following code may reproduce the error:
class _element:NSObject {
}
let _element:UIImage = UIImage()
// type _element under this line
I'm pretty green, but I'm trying to modify a simple program to fit my own needs. You may remember the "BirdWatching" app from "Your Second iOS App: Storyboards" in the iOS Developer's Library.
Anyway, I've refactored most of the names, etc., successfully (it still worked), but then I tried to get rid of a file that kept appearing, even though its name had been expunged (or so I thought) through refactoring. Shows up in the Assistant Editor, right next to the file to which it was refactored.
Now I've got a mess. I tried to move the entire project into it's own folder, but now the compliler won't recognize the info-plist file (says it doesn't exist, and two other files are showing up in red, depending on their position in the navigator. However, it's the WMDG-info.plist that the complier complains about. Specifically, it appears to be following the old path to the file, even after it's been moved and re-added.
I've tried quitting and restarting xCode, re-adding the files, etc. I've searched under every keyword I can think of, but can't find a solution.
Please help!
Thanks!
